Abstract Nanotizing biosealant components offer a multitude of chemical functionalities for superior adhesion–cohesion, delivering unique properties comprehensive wound healing that are otherwise impossible to achieve using commercial variants. For the first time, two‐step controlled hydrothermal pyrolysis is reported nanotize dopamine, phloroglucinol, and glutaraldehyde into carbon dot (CD) be subsequently converted carbonized polymer (CPD) with gelatin as co‐substrate. Chemical crosslinking CD through Schiff base formation before second step ensures complex yet porous polymeric network. The retention indigenous substrates along preservation photoluminescence in CPD optical tracking achieved. A nanoformulation created tannic acid (TA) grafting evolving CPD‐TA nanoglue demonstrating ≈1.32 MPa strength lap shear tests conducted on porcine skin, surpassing traditional bioadhesives. uploaded insulin chosen cargo disbursal at site normal vitro diabetic models HEKa cells extraordinary biocompatibility. Most importantly, can generate reactive oxygen species (ROS) scavenge simultaneously under ambient conditions (23 W white LED or dark) on‐demand sterilization aiding recovery ROS scavenging.

Abstract Islet transplantation is a promising strategy for diabetes mellitus treatment as it can recapitulate endogenous insulin secretion and provide long-term glycemic control. models constructed in biomaterial scaffolds that reproduce biological characteristics of native islets feasible option to circumvent the dilemma donor shortage requirement chronic immunosuppression. Herein, we developed bioinspired artificial microcapsule-based islet with microvessels control using microfluidic electrospray strategy. Microfluidic generate uniform hydrogel microcapsules core-shell structure encapsulating cells. The cell-laden enabled efficient transportation nutrient, oxygen, insulin; well incorporation prompting glucose responsiveness molecular exchange. We demonstrated by vivo experiments blood glucose, food intake, body weight diabetic mouse were alleviated, tolerance was promoted after engraftment microcapsules. further improved functionality transplanted model secretion, immune escape, microcirculation standard histological analysis. These results indicated are valuable treating diabetes.

Surgical excision remains the principal treatment for melanoma, while tumor recurrence and delayed wound healing often occur due to residual cells hypoxic microenvironment in postoperative skin wounds. Herein, we present a living photosynthetic microneedle (MN) patch (namely MA/CM@MN) loaded with microalgae (MA) cuttlefish melanin (CM) postsurgical melanoma therapy healing. Benefiting from oxygenic photosynthesis of alive MA MN base, MA/CM@MN can generate oxygen under light exposure, thus facilitating cell proliferation protecting against hypoxia-induced death. In addition, CM nanoparticles embedded tips, be effectively heated up near-infrared (NIR) irradiation, contributing strong killing efficacy on vitro. Further experiments demonstrate that NIR-irradiated prevents local simultaneously promotes tumor-induced wounds after incomplete resection melanoma-bearing mice, probably because inhibit proliferation, stimulate apoptosis, mitigate tissue hypoxia light. These results indicate offers an effective therapeutic strategy cancer applications.
