Abstract
Although adhesive hydrogels have advanced rapidly in recent years, conventional double-sided adhesives still face challenges in achieving effective adhesion to wet tissues and preventing postoperative tissue adhesion. In this study, a novel Janus hydrogel wet adhesive was successfully designed by precisely regulating the distribution of free hydroxyl and phenolic hydroxyl groups on the two surfaces of the hydrogel. The resulting Janus hydrogel exhibits significantly different adhesive and nonadhesive properties on its upper and lower surfaces. Specifically, through a simple boric acid (BA) solution immersion process, BA cross-linked with poly(vinyl alcohol) (PVA) and tannic acid (TA), effectively suppressing the exposure of hydroxyl groups on the upper surface, leading to low adhesion. In contrast, the lower surface retains strong adhesion to various wet tissues, even underwater. Adhesion simulations with pig skin validated the robust adhesion of the hydrogel's bottom surface to wet tissues, while the low-adhesion upper surface effectively prevented tissue adhesion. Furthermore, cytocompatibility, hemolysis, and coagulation tests demonstrated that the PVA/TA/BA hydrogel possesses excellent biocompatibility and notable hemostatic properties. This simple and efficient preparation strategy offers a practical approach for developing novel Janus hydrogels, laying a solid theoretical and practical foundation for their application in wet tissue repair and postoperative antiadhesion treatments.

Abstract
Lignin-containing cellulose nanofiber (LCNF)-based hydrogels are promising eco-friendly biomaterials, yet the role of lignin in enhancing their adhesion and mechanics remains to be explored. Herein, quaternized lignin-containing cellulose nanofibers (QALCNFs) with varying lignin contents were synthesized from bagasse using a deep eutectic solvent (DES). The relationship between lignin content and the adhesion and mechanical properties of QALCNF hydrogels was systematically investigated. Results demonstrated that lignin in QALCNFs enhanced the hydrogel's gelation time, adhesion and mechanical properties through the provision of quinone/catechol groups, which undergo reversible free radical transformations. As the lignin content decreased, the nanofiber bundles gradually transitioned into more uniform nanofibers, forming a hydrogel with a hierarchical porous structure, superior adhesion, and mechanical properties. Conversely, insufficient lignin content weakened the hydrogel's performance by reducing the quinone/catechol content and decreasing hydrogel porosity. Consequently, QAMLCNF-H exhibited outstanding toughness (2400 J/m2), adhesion strength (114.6 kPa), and high porosity (∼86 %), along with sustained drug release performance, effective antibacterial properties, and excellent cytocompatibility. This study provides a comprehensive understanding of how lignin content in QALCNFs influences hydrogel adhesion, mechanical properties, and drug release behavior, offering valuable insights for the development of high-performance LCNF-based hydrogel biomaterials.

Abstract
Hydrogel tissue adhesives have emerged as a promising alternative to conventional wound closure methods such as sutures and staples due to their operational simplicity demonstrated biocompatibility and capacity for multifunctional integration. However, complex and variable tissue microenvironments and dynamic adhesion surfaces still challenge the actual adhesion performance of adhesives, especially natural polymer-based adhesives. In addition, to expand the application of adhesives in biomedical fields, there is an urgent need to further improve tissue adhesion performance through composition design, adhesion mechanism research and bioeffect development. This review focuses on the adhesive properties of adhesives and their applications in biomedical fields. Adhesion-cohesion equilibria, forms of adhesion failure, methods for improving cohesion and various interfacial adhesion mechanisms are presented. Moreover, practical biomedical applications of tissue adhesives are reviewed, focusing on skin, heart, stomach, liver, and cornea. Finally, this review looks ahead to a new generation of multi-functional, strong adhesion tissue adhesives, in the hope of providing inspiration to those working in the field.

Abstract
Corneal transplantation regeneration requires bioadhesives to perform long-term and stable adhesion functions in a wet environment. However, many current studies focus on the instantaneous or short-term adhesion persistence of bioadhesives, and ignore the evaluation of their long-term wet adhesion behaviors which is urgent for keratoplasty repair process. In view of this situation, a dual covalent cross-linking hydrogel (ASO) bioadhesive is developed. The ASO bioadhesive comprised acrylated gelatin(G-AA), thiolated gelatin(G-SH), and oxidized dextran (OD). Introduction of thiol chemistry made the emergence of ASO dual covalent cross-linking controllable by UV light irradiation. The analysis of this feature revealed an intriguing phenomenon. The ASO bioadhesive demonstrated spatially specific control over cross-linking behavior by first penetrating the tissue and then initiating cross-linking, thereby significantly enhancing its long-term wet adhesion ability. The ASO bioadhesive can maintain more than 50% adhesion after being immersed in wet environment for one month. Subsequently, ASO bioadhesive demonstrated long-term wet adhesive stability once again on corneal lamellar transplantation model through maintaining strong anchorage of corneal donor to recipient bed and promoting their integration. The unprecedented adhesive mechanism presented in this study provided innovated theoretical basis for designing bioadhesives with superior long-term wet adhesion.

Abstract
Effective wound management is critical in post-operative recovery, particularly in sensitive areas such as circumcision. The aim of this study was to design and assess the efficacy of a novel two-component polyurethane (PU) bioadhesive, designated as PU1000S, for its application in advanced wound care within the context of clinical circumcision procedures. The glue-type bioadhesive was fine-tuned to conformally adhere to the moist tissue surfaces. It rapidly absorbed interfacial water and cured within 160 s, ensuring remarkable surface adaptability to wet tissue surfaces. The PU1000S demonstrated superior lap-shear strength, peaking at 55.12 ± 6.88 kPa, along with exceptional durability. These attributes underscored its strong wet adhesion and remarkable resilience at the interface with moist tissues. Owing to its mechanical adaptability to wet skin tissue, the adhesive layer of PU1000S maintained stability under complex loading associated with twisting, folding and significant volumetric deformation, resulting in minimal debonding. In addition, PU1000S was found to significantly accelerate wound healing by promoting re-epithelialization and collagen deposition, confirming its excellent bioadaptability for initial closure and subsequent tissue repair and regeneration following circumcision. The comprehensive results position PU1000S as a promising candidate for advanced wound care in circumcision, offering superior performance in terms of wet adhesion, durability and bioadaptability. Its application could potentially enhance clinical outcomes and elevate patient satisfaction.

Abstract
Bioadhesives have emerged as versatile and powerful tools for tissue repair and integration with biomedical devices, offering a wide range of applications that have captured significant clinical and scientific interest. Synthetic polypeptide adhesives are particularly promising candidates for bioadhesives, but often face limitations in adhesive strength. In this study, inspired by marine adhesive proteins, the secondary structure and hydrophobic-hydrophilic balance of polypeptides were precisely regulated to transform the polyelectrolyte to a strong adhesive. The resulting polypeptide adhesive demonstrated an adhesive strength exceeding 1.0 MPa, more than 10× higher than that of the previously reported synthetic polypeptide adhesive. The cohesion and adhesion of polypeptide adhesive can be optimized by adjusting the content of the secondary structure and hydrophobic residue ratios. More helices in polypeptides enhance the interactions between the polypeptide backbone and side chains as well as the interactions between polypeptides and substrates. In addition, these polypeptide adhesives exhibit excellent tolerance to strong acids or alkalis, remarkable adhesion to variable materials and tissues, and an impressive sealing performance.

Abstract
The hydrogel adhesives with strong tissue adhesion and biological characteristics are urgently needed for injury sealing and tissue repair. However, the negative correlation between tissue adhesion and the mechanical strength poses a challenge for their practical application. Herein, a bio-inspired cohesive enhancement strategy is developed to prepare the hydrogel adhesive with simultaneously enhanced mechanical strength and tissue adhesion. The double cross-linked network is achieved through the cooperation between polyacrylic acid grafted with N-hydroxy succinimide crosslinked by tannic acid and cohesion-enhanced ion crosslinking of sodium alginate and Ca2+. Such a unique structure endows the resultant hydrogel adhesive with excellent tissue adhesion strength and mechanical strength. The hydrogel adhesive is capable of sealing various organs in vitro, and exhibits satisfactory on-demand removability, antibacterial, and antioxidant properties. As a proof of concept, the hydrogel adhesive not only effectively halts non-compressible hemorrhages of beating heart and femoral artery injury models in rats, but also accelerates the healing of infected wound by inhibiting bacteria and reducing inflammation. Overall, this advanced hydrogel adhesive is promising as an emergency rescue adhesive that enables robust tissue closure, timely controlling bleeding, and promoting damaged tissue healing.

Abstract
Highly comminuted fractures and bone defects pose a significant challenge for orthopedic surgery. Current surgical procedures commonly rely on metal implants (such as bone plates, nails and pins) for fracture internal and external fixations, but they are likely to result in problems, such as stress shielding and poor bone healing. Bone adhesive represents an attractive alternative for the treatment of fracture. The ideal bone adhesive should satisfy several performance requirements, including high adhesion strength for bone tissues, rapid in-situ curing in a physiological environment, good biocompatibility with no toxicity, degradability, and good stability in vivo. Among these requirements, degradability is a crucial characteristic of bone adhesives. This property enables the material to be easily removed without the need for surgery at a later stage, ensuring the regeneration of bone tissue without any hindrance. The degradation rate of bone adhesive varies depending on the application scenarios and tissues, ranging from weeks to years. Many bone adhesives are unable to guarantee degradability while achieving other necessary performances. Therefore, this article provides a detailed overview of the strategies to fabricate biodegradable polymer bone adhesives that can maintain high bulk and adhesion strength, biocompatibility and other properties. Finally, the current challenges in the clinical translation of bone adhesives and their future development directions are discussed.

Abstract
The development of wet adhesives capable of bonding in aqueous environments, particularly for hard tissues such as bone, tooth, and cartilage, remains a significant challenge in material chemistry and biomedical research. Currently available hard tissue adhesives in clinical practice lack well-defined wet adhesion properties. Nature offers valuable inspiration through the adhesive mechanisms of marine organisms, advancing the design of bioinspired wet adhesives. Beyond biomimetic approaches, alternative strategies have emerged for the design of wet adhesives. This review systematically summarizes the current design strategies for wet adhesives, focusing on their applications to hard tissues. Then, the unique chemical, physical, mechanical, and biological requirements for wet adhesives applied to hard tissues are also discussed. The importance of understanding natural adhesion mechanisms and the need for high-performance materials that can meet the complex demands of hard tissue adhesion in a complex and delicate physiological microenvironment are highlighted. Finally, this review clarifies the future research directions that can further facilitate the clinical application of wet adhesives for hard tissues. STATEMENT OF SIGNIFICANCE: The significance of this review lies in its comprehensive analysis of wet adhesives for hard tissues, a field that has been largely overlooked despite its critical importance in biomedical applications. The insights gained from studying natural adhesives and the translation of these mechanisms into synthetic materials have the potential to revolutionize medical procedures involving hard tissue repair and regeneration. This review meticulously addresses the distinct challenges and specific requirements of hard tissue adhesives, providing an exhaustive roadmap for researchers striving to develop wet adhesives that can endure the demanding physiological conditions inside the human body. In doing so, it aims to facilitate the transition from laboratory findings to practical clinical applications.

Abstract
Catheter-related infections (CRIs) caused by hospital-acquired microbial infections lead to the failure of treatment and the increase of mortality and morbidity. Surface modifications of the implant catheters have been demonstrated to be effective approaches to improve and largely reduce the bacterial colonization and related complications. In this work, we focus on the last 5-year progress in the surface modifications of biomedical catheters to prevent CRIs. Their antibacterial strategies used for surface modifications are further divided into 5 classifications through the antimicrobial mechanisms, including active surfaces, passive surfaces, active and passive combination surfaces, stimulus-type response surfaces, and other types. Each feature and the latest advances in these abovementioned antibacterial surfaces of implant catheters are highlighted. Finally, these confronting challenges and future prospects are discussed for the antibacterial modifications of implant catheters.

Abstract
Synthetic vinyl polymers have long been recognized for their potential to be utilized in drug delivery, tissue engineering, and other biomedical applications. The synthetic control that chemists have over their structure and properties is unmatched, allowing vinyl polymer-based materials to be precisely engineered for a range of therapeutic applications. Yet, their lack of biodegradability compromises the biocompatibility of vinyl polymers and has held back their translation into clinically used treatments for disease thus far. In recent years, radical ring-opening polymerization (rROP) has emerged as a promising strategy to render synthetic vinyl polymers biodegradable and bioresorbable. While rROP has long been touted as a strategy for preparing biodegradable vinyl polymers for biomedical applications, the translation of rROP into clinically approved treatments for disease has not yet been realized. This review highlights the opportunities for leveraging rROP to render vinyl polymers biodegradable and unlock their potential for use in biomedical applications.

Abstract
Fracture represents one of the most common diagnoses in contemporary medical practice, with the majority of cases traditionally addressed through metallic device fixation. However, this approach is marred by several drawbacks, including prolonged operative durations, considerable expenses, suboptimal applicability to comminuted fractures, increased infection risks, and the inevitable requirement for secondary surgery. The inherent advantages of bone adhesives in these fields have garnered the attention of orthopedic surgeons, who have commenced utilizing biocompatible and biodegradable bone adhesives to bond and stabilize bone fragments. Regrettably, the current bone adhesives generally exhibit insufficient adhesive strength in vivo environments, and it is desirable for them to possess effective osteogenesis to facilitate fracture healing. Consequently, aligning bone adhesives with practical clinical demands remains a significant hurdle, which has catalyzed a surge in research endeavors. Within this review, the conceptual framework, characteristics, and design ideas of bone adhesives based on clinical needs are delineated. Recent advancements in this domain, specifically focusing on the enhancement of two pivotal characteristics-adhesive strength and osteogenic potential are also reviewed. Finally, a prospective analysis of the future advancements in bone adhesives, offering new insights into solutions for diverse clinical problems is presented.

Abstract
The flexible protective coatings and substrates frequently exhibit unstable bonding in industrial applications. For strong interfacial adhesion of heterogeneous materials and long-lasting adhesion of flexible protective coatings even in harsh corrosive environments. Inspired by the interdigitated structures in Phloeodes diabolicus elytra, a straightforward magnetic molding technique is employed to create an interlocking microarray for reinforced heterogeneous assembly. Benefiting from this bio-inspired microarrays, the interlocking polydimethylsiloxane (PDMS) coating recorded a 270% improvement in tensile adhesion and a 520% increase in shear resistance, approaching the tensile limitation of PDMS. The elastic polyurethane-polyamide (PUPI) coating equipped with interlocking structures demonstrated a robust adhesion strength exceeding 10.8 MPa and is nearly unaffected by the corrosion immersion. In sharp contrast, its unmodified counterpart exhibited low initial adhesion and maintain ≈20% of its adhesion strength after 30 d of immersion. PUPI coating integrated with microarrays exhibits superior resistance to corrosion (30 d, |Z|0.01HZ ≈1010 Ω cm2, Rct≈108 Ω cm2), cavitation and long-term adhesion retention. These interlocking designs can also be adapted to curved surfaces by 3D printing and enhances heterogeneous assembly of non-bonded materials like polyvinylidene fluoride (PTFE) and PDMS. This bio-inspired interlocking structures offers a solution for durably bonding incompatible interfaces across varied engineering applications.

Abstract
Injectable adhesive hydrogels combining rapid gelling with robust adhesion to wet tissues are highly required for fast hemostasis in surgical and major trauma scenarios. Inspired by the cross-linking mechanism of mussel adhesion proteins, we developed a bionic double-crosslinked (BDC) hydrogel of poly (γ-glutamic acid) (PGA)/poly (N-(2-hydroxyethyl) acrylamide) (PHEA) fabricated through a combination of photo-initiated radical polymerization and hydrogen bonding cross-linking. The BDC hydrogel exhibited an ultrafast gelling process within 1 s. Its maximum adhesion strength to wet porcine skin reached 254.5 kPa (9 times higher than that of cyanoacrylate (CA) glue) and could withstand an ultrahigh burst pressure of 626.4 mmHg (24 times higher than that of CA glue). Notably, the BDC hydrogel could stop bleeding within 10 s from a rat liver incision 10 mm long and 5 mm deep. The wound treated with the BDC hydrogel healed faster than the control groups, underlining the potential for emergency rescue and wound care scenarios.

Abstract
Efficient interactions between an adhesive and a substrate surface at the molecular level are the basis for the formation of robust adhesion, which substantially relies on interfacial wetting. However, strong adhesives usually improve cohesion but compromise interfacial properties. Herein, we have reported a kind of robust supramolecular adhesive based on the outstanding mobility and interfacial wettability of adhesive precursors. In situ fast photopolymerization endows supramolecular adhesives with more outstanding adhesion for both smooth and rough surfaces in air and underwater in contrast to their counterparts from thermal polymerization. In addition to their low viscosity and high monomer concentration, supramolecular adhesive precursors without any organic solvents possess well-defined hydrogen bonding interactions. These superior properties consistently contribute to the wetting of the substrate and the formation of adhesive polymers with high molecular weights. This work highlights that enhancing interfacial wetting between an adhesive and a substrate is a promising route to achieving robust adhesion.

Abstract
Bone glue with robust adhesion is crucial for treating complicated bone fractures, but it remains a formidable challenge to develop a "true" bone glue with high adhesion strength, degradability, bioactivity, and satisfactory operation time in clinical scenarios. Herein, inspired by the hydroxyapatite and collagen matrix composition of natural bone, we constructed a nanohydroxyapatite (nHAP) reinforced osteogenic backbone-degradable superglue (O-BDSG) by in situ radical ring-opening polymerization. nHAP significantly enhances adhesive cohesion by synergistically acting as noncovalent connectors between polymer chains and increasing the molecular weight of the polymer matrix. Moreover, nHAP endows the glue with bioactivity to promote osteogenesis. The as-prepared glue presented a 9.79 MPa flexural adhesion strength for bone, 4.7 times that without nHAP, and significantly surpassed commercial cyanoacrylate (0.64 MPa). O-BDSG exhibited degradability with 51% mass loss after 6 months of implantation. In vivo critical defect and tibia fracture models demonstrated the promoted osteogenesis of the O-BDSG, with a regenerated bone volume of 75% and mechanical function restoration to 94% of the native tibia after 8 weeks. The glue can be flexibly adapted to clinical scenarios with a curing time window of about 3 min. This work shows promising prospects for clinical application in orthopedic surgery and may inspire the design and development of bone adhesives.
