Abstract
Efficient initiation and resolution of inflammation are crucial for wound repair. However, with using tissue adhesives for wound repair, patients occasionally suffered from delayed healing process because slow elimination of those exogenous adhesives generally leads to chronic inflammation. As the demand for minimal invasive therapy continues to rise, desire for adhesive materials that can effectively reconnect surgical gaps and promote wound regeneration becomes increasingly urgent. Herein, by exploiting the inherent porous structure and performance of adhesion to tissue of mesoporous silica nanoparticles (MSNs), we demonstrate a tissue adhesive that can elicit acute inflammatory response and get eliminated after tissue reformation. With formation of nanocomposites in wound gaps, the injured tissues can get reconnected conveniently. The resultant accelerated healing process verify that the strategy of exploiting unique properties of nanomaterials can effectively promote inflammation resolution and wound repair. This design strategy will inspire more innovative tissue adhesives for clinical applications.
