A Versatile Hydrogel with Antibacterial and Sequential Drug-Releasing Capability for the Programmable Healing of Infectious Keratitis

Exosomes loaded a smart bilayer-hydrogel scaffold with ROS-scavenging and macrophage-reprogramming properties for repairing cartilage defect

“…The elasticity of the hydrogels was considered to be increased as the HA content increased, demonstrating the higher cross-link density of with larger amount of HA. This mechanical stability could provide structural support for the damaged cartilage, transmit mechanical forces effectively, and maintain the shape and integrity during the healing process of joint cartilage [ 38 ]. Hydrogel swelling compresses the surrounding tissues and might even lead to separation from the target organ.…”

Photothermal hydrogels for infection control and tissue regeneration

“…The hydrogel formed a double-layer network structure under light irradiation, providing good anti-inflammatory, antibacterial, proliferative, and tissue-remodeling functions. Moreover, the antibacterial activity of QCSG in SQPV helped to eliminate bacterial contamination around corneal tissue ( Meng et al, 2023 ).…”

Fabrication of a core–shell nanofibrous wound dressing with an antioxidant effect on skin injury

“…Moreover, the SF contents in the coating layer could enhance the biocompatibility 31 of those nanofibers, as SF is a widely used biopolymer in the application of wound healing. 32 This unique structure would promote wound healing and synergize between SF and TA for regulating wound regeneration and oxidative/reductive stress from the wound site (Fig. 1).…”
