Abstract
In this study, we developed a ROS-responsive thermosensitive poly(ethylene glycol)-polypeptide hydrogel loaded with a chemotherapeutic drug, doxorubicin (Dox), an antiviral imidazoquinoline, resiquimod (R848), and antibody targeting programmed cell death protein 1 (aPD-1) for local chemoimmunotherapy. The hydrogel demonstrated controllable degradation and sustained drug release behavior according to the concentration of ROS in vitro. Following intratumoral injection into mice bearing B16F10 melanoma, the Dox/R848/aPD-1 co-loaded hydrogel effectively inhibited tumor growth, prolonged animal survival time and promoted anti-tumor immune responses with low systemic toxicity. In the postoperative model, the Dox/R848/aPD-1 co-loaded hydrogel exhibited enhanced tumor recurrence prevention and long-term immune memory effects. Thus, the hydrogel-based local chemoimmunotherapy system demonstrates potential for effective anti-tumor treatment and suppression of tumor recurrence.

Abstract
This study is about multiple responsiveness in biomedical materials. This typically implies "orthogonality" (i.e., one response does not affect the other) or synergy (i.e., one increases efficacy or selectivity of the other), but an antagonist effect between responses may also occur. Here, we describe a family of very well-defined amphiphilic and micelle-forming block copolymers, which show both oxidative and temperature responses. They are produced via successive anionic ring-opening polymerization of episulfides and RAFT polymerization of dialkylacrylamides and differ only in the ratio between inert (N,N-dimethylacrylamide, DMA) and temperature-sensitive (N,N-diethylacrylamide, DEA) units. By scavenging Reactive Oxygen Species (ROS), these polymers are anti-inflammatory; through temperature responsiveness, they can macroscopically aggregate, which may allow them to form depots upon injection. The localization of the anti-inflammatory action is an example of synergy. An extensive evaluation of toxicity and anti-inflammatory effects on in vitro models, including BV2 microglia, C8D30 astrocytes and primary neurons, shows a link between capacity of aggregation and detrimental effects on viability which, albeit mild, can hinder the anti-inflammatory potential (antagonist action). Although limited in breadth (e.g., only in vitro models and only DEA as a temperature-responsive unit), this study suggests that single-responsive controls should be used to allow for a precise assessment of the (synergic or antagonist) potential of double-responsive systems.

Developments on the Smart Hydrogel-Based Drug Delivery System for Oral Tumor Therapy. Gels 2022; 8:gels8110741.

Abstract
At present, an oral tumor is usually treated by surgery combined with preoperative or postoperative radiotherapies and chemotherapies. However, traditional chemotherapies frequently result in substantial toxic side effects, including bone marrow suppression, malfunction of the liver and kidneys, and neurotoxicity. As a new local drug delivery system, the smart drug delivery system based on hydrogel can control drug release in time and space, and effectively alleviate or avoid these problems. Environmentally responsive hydrogels for smart drug delivery could be triggered by temperature, photoelectricity, enzyme, and pH. An overview of the most recent research on smart hydrogels and their controlled-release drug delivery systems for the treatment of oral cancer is given in this review. It is anticipated that the local drug release method and environment-responsive benefits of smart hydrogels will offer a novel technique for the low-toxicity and highly effective treatment of oral malignancy.

Abstract
Functionalization of silk fibroin hydrogel with antimicrobial activity is essential for promoting the applications of this excellent biomaterial. In this work, a simple approach based on electrostatic interaction is adopted to produce antimicrobial silk hydrogel containing an antimicrobial peptide (AMP), polymyxin B, an important last-line antibiotic to treat multidrug-resistant bacterial superbugs. The polycationic property of this peptide and the negative charge of silk fibroin lead to strong interactions between them, as demonstrated by changes in nanofibril structure, gelation kinetics, ζ-potential, fluorescence emission, and rheological properties of the gel. The hydrogels loaded with polymyxin B demonstrated antimicrobial activity against two Gram-negative bacterial strains. A combination of the results from the different characterizations suggests that the optimal molar ratio of polymyxin B to silk fibroin is 1:2.5. As most AMPs are cationic, this electrostatic approach is suitable for the straightforward functionalization of inert silk hydrogel with other AMPs.

Abstract
The conventional anticancer chemotherapies not only cause serious toxic effects, but also produce resistance in tumor cells exposed to long-term therapy. Usually, the killing of metastasized cancer cells requires long-term therapy with higher drug doses, because the cancer cells develop resistance due to the induction of poly-glycoproteins (P-gps) that act as a transmembrane efflux pump to transport drugs out of the cells. During the last few decades, scientists have been exploring new anticancer drug delivery systems such as microencapsulation, hydrogels, and nanotubes to improve bioavailability, reduce drug-dose requirement, decrease multiple drug resistance, and to save normal cells as non-specific targets. Hopefully, the development of novel drug delivery vehicles (nanotubes, liposomes, supramolecules, hydrogels, and micelles) will assist to deliver drug molecules at the specific target site and reduce the undesirable side effects of anticancer therapies in humans. Nanoparticles and lipid formulations are also designed to deliver small drug payload at the desired tumor cell sites for their anticancer actions. This review will focus on the recent advances in the drug delivery systems, and their application in treating different cancer types in humans.

Abstract
In recent decades, peptides, which can possess high potency, excellent selectivity, and low toxicity, have emerged as promising therapeutics for cancer applications. Combined with an improved understanding of tumor biology and immuno-oncology, peptides have demonstrated robust antitumor efficacy in preclinical tumor models. However, the translation of peptides with intracellular targets into clinical therapies has been severely hindered by limitations in their intrinsic structure, such as low systemic stability, rapid clearance, and poor membrane permeability, that impede intracellular delivery. In this Review, we summarize recent advances in polymer-mediated intracellular delivery of peptides for cancer therapy, including both therapeutic peptides and peptide antigens. We highlight strategies to engineer polymeric materials to increase peptide delivery efficiency, especially cytosolic delivery, which plays a crucial role in potentiating peptide-based therapies. Finally, we discuss future opportunities for peptides in cancer treatment, with an emphasis on the design of polymer nanocarriers for optimized peptide delivery.

Abstract
We synthesize and characterize a triblock polymer with asymmetric tetramethoxyazobenzene (TMAB) and β-cyclodextrin functionalization, taking advantage of the well-characterized azobenzene derivative-cyclodextrin inclusion complex to promote photoresponsive, self-contained folding of the polymer in an aqueous system. We use 1H NMR to show the reversibility of (E)-to-(Z) and (Z)-to-(E) TMAB photoisomerization, and evaluate the thermal stability of (Z)-TMAB and the comparatively rapid acid-catalyzed thermal (Z)-to-(E) isomerization. Important for its potential use as a functional material, we show the photoisomerization cyclability of the polymeric TMAB chromophore and calculate isomerization quantum yields by extinction spectroscopy. To verify self-inclusion of the polymeric TMAB and cyclodextrin, we use two-dimensional 1H NOESY NMR data to show proximity of TMAB and cyclodextrin in the (E)-state only; however, (Z)-TMAB is not locally correlated with cyclodextrin. Finally, the observed decrease in photoisomerization quantum yield for the dual-functionalized polymer compared to the isolated chromophore in an aqueous solution confirms TMAB and β-cyclodextrin not only are in proximity to one another, but also form the inclusion complex.

Abstract
Polymeric hydrogels and microparticles have been widely used for localized drug delivery applications for the treatment of arthritis. Nonetheless, owing to initial burst drug release, non-specific biodistribution and low retention time at the target site in body, these polymeric drug delivery systems have been found with low in-vivo performance. Hence, the above limitations need to be resolved by designing a smart novel drug delivery system which is the current need in biomedicine. Herein, a novel localized injectable thermoresponsive microparticles embedded hydrogel composite drug delivery system has been developed for the treatment of inflammatory arthritis. In the current study, methotrexate (MTX) loaded alginate microparticles (MTX-Microparticles) are embedded into thermoreversible hydrogel matrix (MTX-MPs-H) prepared by physical blending of sodium hyaluronate and methylcellulose (SHMC). Microparticles-hydrogel composite system exhibited appropriate in-vitro thermoreversibility (sol at 4 °C and gel at 37 °C), biocompatibility (>80 %), hemocompatibility, and controlled drug release profile. The in-vivo biocompatibility studies for 10 days revealed that composite system is non-toxic in nature. The developed MTX-MPs-H composite drug delivery system effectively decreased the swelling/ inflammation of the arthritis affected paw in wistar rats in comparison to only alginate microparticles and pure MTX up to 30 days.

Abstract
Local drug delivery approaches for treating brain tumors not only diminish the toxicity of systemic chemotherapy, but also circumvent the blood-brain barrier (BBB) which restricts the passage of most chemotherapeutics to the brain. Recently, salinomycin has attracted much attention as a potential chemotherapeutic agent in a variety of cancers. In this study, poly (ethylene oxide)/poly (propylene oxide)/poly (ethylene oxide) (PEO-PPO-PEO, Pluronic F127) and poly (dl-lactide-co-glycolide-b-ethylene glycol-b-dl-lactide-co-glycolide) (PLGA-PEG-PLGA), the two most common thermosensitive copolymers, were utilized as local delivery systems for salinomycin in the treatment of glioblastoma. The Pluronic and PLGA-PEG-PLGA hydrogels released 100% and 36% of the encapsulated salinomycin over a one-week period, respectively. While both hydrogels were found to be effective at inhibiting glioblastoma cell proliferation, inducing apoptosis and generating intracellular reactive oxygen species, the Pluronic formulation showed better biocompatibility, a superior drug release profile and an ability to further enhance the cytotoxicity of salinomycin, compared to the PLGA-PEG-PLGA hydrogel formulation. Animal studies in subcutaneous U251 xenograftednudemice also revealed that Pluronic + salinomycin hydrogel reduced tumor growth compared to free salinomycin- and PBS-treated mice by 4-fold and 6-fold, respectively within 12 days. Therefore, it is envisaged that salinomycin-loaded Pluronic can be utilized as an injectable thermosensitive hydrogel platform for local treatment of glioblastoma, providing a sustained release of salinomycin at the tumor site and potentially bypassing the BBB for drug delivery to the brain.

Abstract
Cancer immunotherapy aims to leverage the immune system to suppress the growth of tumors and to inhibit metastasis. The recent promising clinical outcomes associated with cancer immunotherapy have prompted research and development efforts towards enhancing the efficacy of immune checkpoint blockade, cancer vaccines, cytokine therapy, and adoptive T cell therapy. Advancements in biomaterials, nanomedicine, and micro-/nano-technology have facilitated the development of enhanced local delivery systems for cancer immunotherapy, which can enhance treatment efficacy while minimizing toxicity. Furthermore, locally administered cancer therapies that combine immunotherapy with chemotherapy, radiotherapy, or phototherapy have the potential to achieve synergistic antitumor effects. Herein, the latest studies on local delivery systems for cancer immunotherapy are surveyed, with an emphasis on the therapeutic benefits associated with the design of biomaterials and nanomedicines. This article is categorized under: Nanotechnology Approaches to Biology > Nanoscale Systems in Biology Therapeutic Approaches and Drug Discovery > Nanomedicine for Oncologic Disease.

Abstract
Cell therapy for spinal cord injuries offers the possibility of replacing lost cells after trauma to the central nervous system (CNS). In preclinical studies, synthetic hydrogels are often co-delivered to the injury site to support survival and integration of the transplanted cells. These hydrogels ideally mimic the mechanical and biochemical features of a healthy CNS extracellular matrix while also providing the possibility of localized drug delivery to promote healing. In this work, we synthesize peptide-functionalized polymers that contain both a peptide sequence for incorporation into self-assembled peptide hydrogels along with bioactive peptides that inhibit scar formation. We demonstrate that peptide hydrogels formulated with the peptide-functionalized polymers possess similar mechanical properties (soft and shear-thinning) as peptide-only hydrogels. Small angle neutron scattering analysis reveals that polymer-containing hydrogels possess larger inhomogeneous domains but small-scale features such as mesh size remain the same as peptide-only hydrogels. We further confirm that the integrated hydrogels containing bioactive peptides exhibit thrombin inhibition activity, which has previously shown to reduce scar formation in vivo. Finally, while the survival of encapsulated cells was poor, cells cultured on the hydrogels exhibited good viability. Overall, the described composite hydrogels formed from self-assembling peptides and peptide-modified polymers are promising, user-friendly materials for CNS applications in regeneration.

Abstract
Introduction Gambogic acid (GA) is proved to have anti-tumor effects on gastric cancer. Due to poor solubility, non-specific biological distribution, toxicity to normal tissues and short half-life, it is hard to be applied into the clinic. To overcome these issues, we developed a thermosensitive and injectable hydrogel composed of hydroxypropyl cellulose, silk fibroin and glycerol, with short gelling time, good compatibility and sustained release, and demonstrated that the hydrogel packaged with gambogic acid nanoparticles (GA-NPs) and tumor-penetrating peptide iRGD could improve the anti-tumor activity. Methods The Gelling time and micropore size of the hydrogels were regulated through different concentrations of glycerol. Controlled release characteristics of the hydrogels were evaluated with a real-time near-infrared fluorescence imaging system. Location of nanoparticles from different carriers was traced by confocal laser scanning microscopy. The in vivo antitumor activity of the hydrogels packaging GA-NPs and iRGD was evaluated by investigating tumor volume and tumor size. Results The thermo-sensitive properties of hydrogels were characterized by 3-4 min, 37°C, when glycerol concentration was 20%. The hydrogels physically packaged with GA-NPs and iRGD showed higher fluorescence intensity than other groups. The in vivo study indicated that the co-administration of GA-NPs and iRGD by hydrogels had higher antitumor activity than the GA-loaded hydrogels and free GA combining with iRGD. Free GA group showed few antitumor effects. Compared with the control group, the body weight in other groups had no obvious change, and the count of leukocytes and hemoglobin was slightly decreased. Discussion The hydrogel constructed iRGD and GA-NPs exerted an effective anti-tumor effect possibly due to retention effect, local administration and continuous sustained release of iRGD promoting the penetration of nanoparticles into a deep part of tumors. The delivery system showed little systemic toxicity and would provide a promising strategy to improve anti-gastric cancer efficacy.

Abstract
Nanoparticle (NP)-based hydrogels that can introduce synergistic advantages to the novel three-dimensional scaffold have garnered much attention recently. However, the application of NP-crosslinked hydrogels still remains challenging due to the complicated synthesis and/or modification of the NPs and the changed properties of the NPs after gelation. Herein, a novel palladium nanosheet (Pd NS)-based hydrogel (Pd Gel) with Pd NSs as crosslinkers was obtained by simply mixing Pd NSs with thiol-terminated four-arm polyethylene glycol (4arm-PEG-thiol). It was found that the formed Pd Gel was injectable, possibly due to the dynamic Pd-S bonds formed between Pd NSs and 4arm-PEG-thiol. In addition, compared with free Pd NSs, the Pd NSs within the hydrogel exhibited a significantly higher stability. We have further demonstrated that the formed hydrogel could encapsulate the commonly used anticancer drug doxorubicin (DOX) to form DOX@Pd Gel for combined chemo-photothermal therapy. Particularly, Pd NSs with a high absorption in the near-infrared (NIR) region could convert the energy of NIR laser into heat with a high efficiency, which is beneficial for photothermal therapy. Moreover, DOX@Pd Gel could maintain a sustainable release of DOX and the NIR laser irradiation could accelerate this drug release process. Then, the explosively released DOX and the hyperthermia generated from Pd NSs under NIR laser irradiation acted in a synergistic way to realize the combined therapeutic effect of the chemo-photothermal treatment. Finally, the in vivo anticancer effect and safety of the combined therapy were also verified by the tumor-bearing mouse model. Taken together, this work constructs a NP-crosslinked, NIR laser-activatable and injectable photothermal hydrogel via dynamic Pd-S bonding, and demonstrates that the hydrogel allows us to release DOX more precisely, eliminate tumor more effectively and inhibit tumor metastasis more persistently, which will advance the development of novel anticancer strategies.

Abstract
Improving the efficiency of chemotherapy remains a key challenge in drug delivery. Many drug carriers have been designed to achieve multifunctional factors as part of their performance, including controlled release, dispersibility in aqueous environments, and targeting to cancer sites. However, it is difficult to optimize multiple properties simultaneously for a single carrier system. Here, synergistic carriers composed of vaterite microspheres and silk nanofiber hydrogels were developed to improve the dispersibility of vaterite spheres and the control of drug delivery without compromising the injectability or sensitivity to pH. The vaterite microspheres were dispersed homogeneously and remained stable in the silk nanofiber hydrogels. Doxorubicin (DOX) was effectively loaded on the vaterite spheres and silk nanofibers, forming synergistic silk-vaterite hydrogel delivery systems. The sustained delivery of DOX was tuned and controlled by vaterite stability and the DOX content loaded on the spheres and nanofibers. The cytotoxicity was regulated via the controlled delivery of DOX, suggesting the possibility of optimizing chemotherapeutic strategies. These silk-vaterite delivery hydrogels suggest a useful strategy for designing novel delivery systems for improved delivery and therapeutic benefits.

Abstract
In a malignant tumor, overexpression of pro-angiogenic factors like vascular endothelial growth factor (VEGF) provokes the production of pathologic vascular networks characterized by leaky, chaotically organized, immature, thin-walled, and ill-perfused. As a result, hostile tumor environment would be developed and profoundly hinders anti-cancer drug activities and fuels tumor progression. In this study, we develop a strategy of sequential sustain release of anti-angiogenic drug, Bevacizumab (BVZ), and anti-cancer drug, Doxorubicin (DOX), using poly (d, l-Lactide)- Poly (ethylene glycol) -Poly (d, l-Lactide) (PDLLA-PEG-PDLLA) hydrogel as a local delivery system. The release profiles of the drugs from the hydrogel were investigated in vitro which confirmed that relatively rapid release of BVZ (73.56 ± 1.39%) followed by Dox (61.21 ± 0.62%) at pH 6.5 for prolonged period. The in vitro cytotoxicity test revealed that the copolymer exhibited negligible cytotoxicity up to 2.5 mg ml-1 concentration on HaCaT and HeLa cells. Likeways, the in vitro degradation of the copolymer showed 41.63 ± 2.62% and 73.25 ± 4.36% weight loss within 6 weeks at pH 7.4 and 6.5, respectively. After a single intratumoral injection of the drug-encapsulated hydrogel on Hela xenograft nude, hydrogel co-loaded with BVZ and Dox displayed the highest tumor suppression efficacy for up to 36 days with no noticeable damage on vital organs. Therefore, localized co-delivery of anti-angiogenic drug and anti-cancer drug by hydrogel system may be a promising approach for enhanced chemotherapeutic efficacy in cancer treatment.

Abstract
Traditional intravenous chemotherapy is relative to many systemic side effects, including myelosuppression, liver or kidney dysfunction, and neurotoxicity. As an alternative method, the injectable hydrogel can efficiently avoid these problems by releasing drugs topically at the tumor site. With advantages of localized drug toxicity in the tumor site, proper injectable hydrogel as the drug delivery system has become a research hotspot. Based on different types and stages of cancer, a variety of hydrogel drug delivery systems were developed, including thermosensitive, pH-sensitive, photosensitive, and dual-sensitive hydrogel. In this review, the latest developments of these hydrogels and related drug delivery systems were summarized. In summary, our increasing knowledge of injectable hydrogel for localized cancer therapy ensures us that it is a more durable and effective approach than traditional chemotherapy. Smart release system reacting to different stimuli at different time according to the micro-environment changes in the tumor site is a promising tendency for further studies.

To date, much of the work relies on controlling polymer behavior by varying the monomer side chains to add functionality and tune hydrophobicity. Although varying the side chains is an efficient strategy to control polymer behavior, changing the polymer backbone can also be a powerful approach to modulate polymer self-assembly, rigidity, reactivity, and biodegradability for biomedical applications. There are many developments in the syntheses of polymers with segmented backbones, but these developments are not widely adopted as strategies to address the unique constraints and requirements of polymers for biomedical applications. This review highlights dual polymerization strategies for the synthesis of backbone-segmented block copolymers to facilitate their adoption for biomedical applications.

Improved anti-colorectal carcinomatosis effect of tannic acid co-loaded with oxaliplatin in nanoparticles encapsulated in thermosensitive hydrogel. Eur J Pharm Sci 2018; 128:279-289.

Abstract
Tannic acid, a hydrolysable tannin, exists commonly in food plants. Tannic acid has already been shown various anticancer mechanisms such as inhibiting the proliferation, inducing a higher apoptotic rate and slowing down the metastasis of different cancers. Moreover, tannic acid was reported to reduce the side effects caused by chemotherapeutics on patients. But whether the tannic acid can improve the treatment of oxaliplatin on colorectal carcinomatosis has yet been studied. In this study, we developed an injectable drug delivery system by physical incorporation of oxaliplatin (OXA) and tannic acid (TA) polymeric nanoparticles (OXA/TA NPs) into a thermo-sensitive hydrogel, OXA/TA NPs-hydrogel (OXA/TA NPs-H). The OXA/TA NPs-H was injected into the peritoneal cavity for the treatment of colorectal peritoneal carcinoma. Firstly, a water-in-oil-in-water double-emulsion (w/o/w) method and solvent-evaporation procedure were used in the preparation of the biodegradable OXA/TA NPs. Then, we prepared the biodegradable thermo-sensitive poly(3-caprolactone) (PCL)-10R5-PCL (PCLR) hydrogel with a low critical solution temperature (LCST) which undergoes gelation process at body temperature. Transmission electron microscopy (TEM) showed the spherical profile of OXA/TA NPs. Fourier-transform infrared (FTIR) spectra demonstrated that OXA and TA were both encapsulated into the OXA/TA NPs. In this study, intraperitoneal application of OXA/TA NPs-H restricted the growth of CT26 peritoneal colon cancer in vivo, improved the quality of life and prolonged the survival time of the model mice. Our study suggested that OXA/TA NPs-H might have potential application in the treatment of colorectal cancer.

Abstract
The macroscale delivery system has been one of the practical platforms for a controlled delivery system by acting as a local depot close to the target tissue. In this study, we fabricated a macroporous alginate crygel incorporated with gold nanorods (GNRs) for the on-demand release of a chemotherapeutic drug from macroscale materials placed beside the target tumor. The macroporous crygel was prepared by the ice-crystal templating of a covalently crosslinked alginate hydrogel incorporated with GNRs. Mitoxantrone (MX), one of the potent anticancer drugs with a positive charge, was strongly adsorbed on the negative alginate chains of the cryogels. This system enabled a high loading of MX and a successful on-demand release of strongly bound MX from the GNR-loaded macroporous cryogels by near-infrared (NIR) irradiation by the dissociation of the interaction between the alginate backbone and MX. Cell viability after the NIR irradiation of the MX-loaded macroporous cryogel was significantly lower compared to that under no stimuli conditions. The in vivo test showed that repetitive NIR irradiations on the MX-loaded cryogel implanted near the tumor suppressed the tumor volume six times more than that of the control group. This simple approach to fabricate a macroporous cryogel capable of the on-demand release of bioactive cargos could be beneficial in various applications including cell, gene, and the other small molecule delivery systems.

Abstract
Injectable and malleable hydrogels that combine excellent biocompatibility, physiological stability, and ease of use are highly desirable for biomedical applications. Here, a simple and scalable strategy is reported to make injectable and malleable zwitterionic polycarboxybetaine hydrogels, which are superhydrophilic, nonimmunogenic, and completely devoid of nonspecific interactions. When zwitterionic microgels are reconstructed, the combination of covalent crosslinking inside each microgel and supramolecular interactions between them gives the resulting zwitterionic injectable pellet (ZIP) constructs supportive moduli and tunable viscoelasticity. ZIP constructs can be lyophilized to a sterile powder that fully recovers its strength and elasticity upon rehydration, simplifying storage and formulation. The lyophilized powder can be reconstituted with any aqueous suspension of cells or therapeutics, and rapidly and spontaneously self-heals into a homogeneous composite construct. This versatile and highly biocompatible platform material shows great promise for many applications, including as an injectable cell culture scaffold that promotes multipotent stem cell expansion and provides oxidative stress protection.

Abstract
AbstractThe purpose of this investigation is to develop a dual pH-/temperature-responsive and fluorescent hydrogel based on piperazine and Pluronic F127 (PF127). Firstly, polyurethane was synthesized using 1,6-hexamethylene diisocyanate, 1,4-bis(hydroxyethyl) piperazine, and PF127 by a step polymerization process. Erythrosine B (EB) is then incorporated into copolymers to offer a fluorescence property. The polyurethane-PF127-EB copolymer can spontaneously self-assemble into hydrogels with a great number of closely packed micelles, and the hydrogels also have the ability to undergo thermo-sensitive sol-gel phase transition above the critical gelation concentration. The gelation temperature can be adjusted near the physiological condition by modulating the concentration of the copolymer in an aqueous medium. The acid-titration curves indicate a good pH-responsive property, and the UV-vis and fluorescence spectra exhibit strong self-fluorescence signals for hydrogels. As a result, the hydrogels not only can serve as drug carriers but can also be utilized as fluorescence imaging probes in biomedical applications.

Abstract
Hydrogels are promising 3D materials that have demonstrated increasing applications in the encapsulation and delivery of drugs and cells. Herein we report an injectable colloidal hydrogel that directly assembled by graphene oxide (GO) and thermo-sensitive nanogels (tNG). The pH dependent hydrogen bonding interactions between the carboxyl and oxethyl groups induce the reversible assembly of GO and nanogels. The hydrogel is mouldable and can be shaped into different macroscopic objects, and the mechanical strengths are tunable with pH and temperature adjustment. The hybrid hydrogel by its own possesses high antibacterial activity, and demonstrates responsive drug release behaviour and high viability of 3D encapsulated cells. We expect this hybrid colloidal hydrogel can serve as an interesting scaffold for active cargo delivery and cell culture.

Abstract
Systemic administration of therapeutic agents has been the preferred approach to treat most pathological conditions, in particular for cancer therapy. This treatment modality is associated with side effects, off-target accumulation, toxicity, and rapid renal and hepatic clearance. Multiple efforts have focused on incorporating targeting moieties into systemic therapeutic vehicles to enhance retention and minimize clearance and side effects. However, only a small percentage of the nanoparticles administered systemically accumulate at the tumor site, leading to poor therapeutic efficacy. This has prompted researchers to call the status quo treatment regimen into question and to leverage new delivery materials and alternative administration routes to improve therapeutic outcomes. Recent approaches rely on the use of local delivery platforms that circumvent the hurdles of systemic delivery. Local administration allows delivery of higher "effective" doses while enhancing therapeutic molecules' stability, minimizing side effects, clearance, and accumulation in the liver and kidneys following systemic administration. Hydrogels have proven to be highly biocompatible materials that allow for versatile design to afford sensing and therapy at the same time. Hydrogels' chemical and physical versatility can be exploited to attain disease-triggered in situ assembly and hydrogel programmed degradation and consequent drug release, and hydrogels can also serve as a biocompatible depot for local delivery of stimuli-responsive therapeutic cargo. We will focus this Account on the hydrogel platform that we have developed in our lab, based on dendrimer amine and dextran aldehyde. This hydrogel is disease-responsive and capable of sensing the microenvironment and reacting in a graded manner to diverse pathologies to render different properties, including tissue adhesion, biocompatibility, hydrogel degradation, and embedded drug release profile. We also studied the degradation kinetics of our stimuli-responsive materials in vivo and analyzed the in vitro conditions under which in vitro-in vivo correlation is attained. Identifying key parameters in the in vivo microenvironment under healthy and disease conditions was key to attaining that correlation. The adhesive capacity of our dendrimer-dextran hydrogel makes it optimal for localized and sustained release of embedded drugs. We demonstrated that it affords the delivery of a range of therapeutics to combat cancer, including nucleic acids, small molecules, and antibody drugs. As a depot for local delivery, it allows a high dose of active biomolecules to be delivered directly at the tumor site. Immunotherapy, a recently blooming area in cancer therapy, may exploit stimuli-responsive hydrogels to impart systemic effects following localized therapy. Local delivery would enable release of the proper drug dose and improve drug bioavailability where needed at the same time creating memory and exerting the therapeutic effect systemically. This Account highlights our perspective on how local and systemic therapies provided by stimuli-responsive hydrogels should be used to impart more precise, long-lasting, and potent therapeutic outcomes.

Abstract
Common chemotherapy is often associated with adverse effects in normal cells and tissues. As an alternative approach, localized chemotherapy can diminish the toxicity of systemic chemotherapy while providing a sustained release of the chemotherapeutics at the target tumor site. Therefore, injectable biodegradable hydrogels as drug delivery systems for chemotherapeutics have become a matter of importance. Here, we review the application of a variety of injectable hydrogel-based drug delivery systems, including thermosensitive, pH-sensitive, photosensitive, dual-sensitive, as well as active targeting hydrogels, for the treatment of different types of cancer. Generally, injectable hydrogel-based drug delivery systems are found to be more efficacious than the conventional systemic chemotherapy in terms of cancer treatment.

Abstract
Silk is useful as a drug carrier due to its biocompatibility, tunable degradation, and outstanding capacity in maintaining the function of drugs. Injectable silk hydrogels could deliver doxorubicin (DOX) for localized chemotherapy for breast cancer. To improve hydrogel properties, thixotropic silk nanofiber hydrogels in an all-aqueous solution were prepared and used to locally deliver DOX. The silk hydrogels displayed thixotropic capacity, allowing for easy injectability followed by solidification in situ. The hydrogels were loaded with DOX and released the drug over eight weeks with pH- and concentration-dependent release kinetics. In vitro and in vivo studies demonstrated that DOX-loaded silk hydrogels had good antitumor response, outperforming the equivalent dose of free DOX administered intravenously. Thixotropic silk hydrogels provide improved injectability to support sustained release, suggesting promising applications for localized chemotherapy.
