Existing tissue [[adhesive]]s and [[sealant]]s are far from satisfactory when applied on wet and dynamic tissues. Li et al. reported a strategy for designing biodegradable super-strong aqueous glue (B-Seal) for surgical uses inspired by an English ivy adhesion strategy and a cement particle packing theory. B-Seal is a fast-gelling, super-strong, and elastic adhesive sealant composed of injectable water-borne biodegradable [[polyurethane]] (WPU) nanodispersions with mismatched particle sizes and counterions in its A-B formulation. B-Seal showed 24-fold greater burst pressure than [[DuraSeal]]®, 138-fold greater T-pull adhesive strength than [[fibrin glue]], and 16-fold greater lap shear strength than fibrin glue. In vivo evaluation on a rat cerebrospinal fluid (CSF) rhinorrhea model and a porcine craniotomy model validated the safety and efficacy of B-Seal for effective Cerebrospinal fluid fistula prevention and dura repair. The plant-inspired adhesion strategy combined with particle packing theory represents a new direction of designing the next-generation wet tissue adhesives for surgeries ((Li Q, Song W, Li J, Ma C, Zhao X, Jiao J, Mrowczynski O, Webb BS, Rizk EB, Lu D, Liu C.
