Strategies for improving adhesion and mechanical properties of polyester adhesives. (a) Hyperbranched polyester was cured by photoinitiation of the thiol-ene click reaction to create a highly crosslinked tissue adhesive [69]. (b) Nanobioactive glass-reinforced propylene fumarate (PPF) bone adhesives [71]. (c) NHS-modified PLGA biodegradable nanoparticles with dopamine-modified alginate to enhance tissue adhesion through three interactions between tissues and nanocomposite adhesive [72]. (d) Schematic illustration of flexible gelatin coated PCL nanopatch [73].
