Abstract
The clinical need for photodynamic therapy (PDT) has been growing for several decades. Notably, PDT is often used in oncology to treat a variety of tumors since it is a low-risk therapy with excellent selectivity, does not conflict with other therapies, and may be repeated as necessary. The mechanism of action of PDT is the photoactivation of a particular photosensitizer (PS) in a tumor microenvironment in the presence of oxygen. During PDT, cancer cells produce singlet oxygen (1O2) and reactive oxygen species (ROS) upon activation of PSs by irradiation, which efficiently kills the tumor. However, PDT's effectiveness in curing a deep-seated malignancy is constrained by three key reasons: a tumor's inadequate PS accumulation in tumor tissues, a hypoxic core with low oxygen content in solid tumors, and limited depth of light penetration. PDTs are therefore restricted to the management of thin and superficial cancers. With the development of nanotechnology, PDT's ability to penetrate deep tumor tissues and exert desired therapeutic effects has become a reality. However, further advancement in this field of research is necessary to address the challenges with PDT and ameliorate the therapeutic outcome. This review presents an overview of PSs, the mechanism of loading of PSs, nanomedicine-based solutions for enhancing PDT, and their biological applications including chemodynamic therapy, chemo-photodynamic therapy, PDT-electroporation, photodynamic-photothermal (PDT-PTT) therapy, and PDT-immunotherapy. Furthermore, the review discusses the mechanism of ROS generation in PDT advantages and challenges of PSs in PDT.

Abstract
Nanocarriers can be used to deliver insoluble anticancer drugs to optimize therapeutic efficacy. However, the potential toxicity of nanocarriers cannot be ignored. Carrier-free nanodrugs are emerging safe drug delivery systems, which are composed of multiple components, such as drugs, bioactive molecules and functional ingredients, avoiding the usage of inert carrier materials and offering advantages that include high drug loading, low toxicity, synergistic therapy, versatile design, and easy surface functionalization. Therefore, how to design multicomponent carrier-free nanodrugs is becoming a priority. In this review, the common strategies for rapid construction of multicomponent carrier-free nanodrugs are briefly explored from the perspective of methodology. The properties of organic-organic, organic-inorganic and inorganic-inorganic multiple carrier-free nanosystems are analyzed according to wettability and in-depth understanding is provided. Further advances in the applications of multiple carrier-free nanodrugs are outlined in anticipation of grasping the intrinsic nature for the design and development of carrier-free nanodrugs.

Abstract
Metal-organic frameworks (MOFs) are a class of important porous, crystalline materials composed of metal ions (clusters) and organic ligands. Owing to the unique redox chemistry, photochemical and electrical property, and catalytic activity of Cu2+/+, copper-based MOFs (Cu-MOFs) have been recently and extensively explored in various biomedical fields. In this review, we first make a brief introduction to the synthesis of Cu-MOFs and their composites, and highlight the recent synthetic strategies of two most studied representatives, three-dimensional HKUST-1 and two-dimensional Cu-TCPP. The recent advances of Cu-MOFs in the applications of cancer treatment, bacterial inhibition, biosensing, biocatalysis, and wound healing are summarized and discussed. Furthermore, we propose a prospect of the future development of Cu-MOFs in biomedical fields and beyond.

Abstract
The complexity of the tumor microenvironment presents significant challenges to cancer therapy, while providing opportunities for targeted drug delivery. Using characteristic signals of the tumor microenvironment, various stimuli-responsive drug delivery systems can be constructed for targeted drug delivery to tumor sites. Among these, the pH is frequently utilized, owing to the pH of the tumor microenvironment being lower than that of blood and healthy tissues. pH-responsive polymer carriers can improve the efficiency of drug delivery in vivo, allow targeted drug delivery, and reduce adverse drug reactions, enabling multifunctional and personalized treatment. pH-responsive polymers have gained increasing interest due to their advantageous properties and potential for applicability in tumor therapy. In this review, recent advances in, and common applications of, pH-responsive polymer nanomaterials for drug delivery in cancer therapy are summarized, with a focus on the different types of pH-responsive polymers. Moreover, the challenges and future applications in this field are prospected.

Abstract
A peptide/DNA nanocomplex was developed for the targeted delivery of chemotherapeutics and photosensitizers to cancer cells for efficient combination therapy. The chemotherapeutic drug doxorubicin (DOX) and the photosensitizer 5,10,15,20-tetra-(1-methylpyridine-4-yl)-porphyrin (TMPyP4) were physically incorporated by an aptamer (AS1411)-modified tetrahedral DNA nanostructure, where the tetrahedral DNA and aptamer-induced G-quadruplex provide binding sites of DOX and TMPyP4. The co-loaded 3A-TDN/DT displayed a targeted uptake by HeLa cancer cells through the high affinity and specificity between AS1411 and nucleolin, a protein overexpressed on many types of cancer cells. A polycationic polymer, mPEG-PAsp(TECH), was synthesized to complex with the DNA nanostructure to efficiently escape from lysosomes via the proton sponge effect upon the enhanced internalization by tumor cells. Under the irradiation of 660 nm laser light, TMPyP4 induced an upregulation of intracellular reactive oxygen species, which combined with DOX to fulfill the efficient inhibition of HeLa cells. Our study demonstrated a biocompatible peptide/DNA composite nanoplatform for combinational cancer therapy via the targeted delivery of therapeutic agents and efficient lysosomal escape.

Abstract
The common existence of hypoxia within the tumor microenvironment severely restricts the efficacy of photodynamic therapy (PDT), which is attributed to the fact that the PDT process is strongly oxygen (O2) dependent. Here, a multifunctional composite (named CPCG), which combines polyethylene glycol (PEG) functionalized cerium oxide nanoparticles (CeO2) with photosensitizer chlorin e6 (Ce6) and glucose oxidase (GOx), is reported for generating O2 within the tumor microenvironment by the dual-path hydrogen peroxide (H2O2)-modulated ways to ameliorate hypoxia, thereby enhancing the PDT efficiency. This process is realized based on the dual enzyme-like activity of CeO2. The first modulated way is to transform the superoxide anion (O2˙-) into H2O2 by the superoxide dismutase-like activity of CeO2. The second modulated way is to decompose glucose into H2O2 through the catalysis of GOx. Subsequently, H2O2 generated from the above dual modulated ways can further produce O2via the catalase-like activity of CeO2. Additionally, the depletion of glucose could impede the nutrient supply to obtain starvation therapy. Both in vitro and in vivo experiments indicate that the CPCG composite could enhance the efficacy of photodynamic/starvation synergistic therapy. Therefore, this strategy offers great potential to modulate the O2 level in the tumor microenvironment for better therapeutic outcomes, and can act as a promising candidate in photodynamic/starvation synergistic therapy.

Abstract
In this study, we reported a nanocomplex (PAF) of PEGylated polygalacturonic acid, 5,10,15,20-tetrakis (4-aminophenyl) porphyrin (TAPP), and Fe3+ for photodynamic therapy (PDT)-enhanced ferroptosis in cancer treatment. PAF exhibited a size of 135 nm and a TAPP and Fe3+ loading content of 6.99 and 0.77%, respectively. The singlet oxygen (1O2) generation capacity of TAPP can be activated and significantly enhanced at acidic pH (4.5-5.0). Besides, the enhanced near-infrared absorption of TAPP at acidic pH enabled a further increase in 1O2 generation capability by a near-infrared laser (760 nm). The polysaccharide-based polymer carrier offers excellent biocompatibility, and PAF displayed a proliferative effect in both normal (L929) and cancer (B16) cells. However, upon light irradiation, PAF exhibited high toxicity to B16 melanoma cells by intracellular reactive oxygen species elevation, glutathione depletion, and lipid peroxidation. PAF displayed a much better anticancer effect than the nanocomplex containing Fe3+ or TAPP alone, indicating the PDT-enhanced ferroptosis in PAF. This study suggested that PDT-enhanced ferroptosis could be a facile and robust strategy of nanotherapeutics with high potency, tumor selectivity, and excellent biocompatibility.

Abstract
We study the nonequilibrium diffusive release of electroneutral molecular cargo encapsulated inside hollow hydrogel nanoparticles. We propose a theoretical model that includes osmotic, steric, and short-range polymer-cargo attractions to determine the effective cargo-hydrogel interaction, ueff*, and the effective diffusion coefficient of the cargo inside the polymer network, Deff*. Using dynamical density functional theory (DDFT), we investigate the scaling of the characteristic release time, τ1/2, with the key parameters involved in the process, namely, ueff*, Deff*, and the swelling ratio. This effort represents a full study of the problem, covering a broad range of cargo sizes and providing predictions for repulsive and attractive polymer shells. Our calculations show that the release time through repulsive polymer networks scales with q2eβueff*/Deff* for βueff* ≫ 1. In this case, the cargo molecules are excluded from the shell of the hydrogel. For attractive shells, the polymer retains the cargo molecules on its internal surface and its interior, and the release time grows exponentially with the attraction strength. The DDFT calculations are compared to an analytical model for the mean first passage time, which provides an excellent quantitative description of the kinetics for both repulsive and attractive shells without fitting parameters. Finally, we apply the method to reproduce experimental results on the release of paclitaxel from hollow poly(4-vinylpyridine) nanoparticles and find that the slow release of the drug can be explained in terms of the strong binding attraction between the drug and the polymer.

Abstract
With the utilization of high concentration reactive oxygen species (ROS) in tumor microenvironment, PEG-doxorubicin (PEG-DOX) prodrug was synthesized via a thioketal moiety as the linker, which was ROS cleavable to trigger DOX release from the self-assembled prodrug nanoparticles. The in vitro ROS sensitivity of prodrug nanoparticles (NPs) was investigated in Fenton agent and H2O2, and the disassembly of NPs was more sensitive to Fenton reagent. After internalized in HepG2 cells via endocytosis, the cellular ROS consuming test revealed intracellular DOX release. The pharmacokinetics and biodistribution study demonstrated that the in vivo elimination of NPs was significantly improved and the NPs were passively targeted to tumor tissues via EPR effect. The ROS-responsive prodrug NPs exhibited excellent antitumor activity in HepG2 tumor-bearing nude mice, remarkably induced tumor cells apoptosis and reduced the systemic toxicity of DOX. Our study revealed the ROS responsive prodrug nanoparticle is an effective strategy to fabricate nanomedicine for cancer chemotherapy.
