Fig. 1. Engineering PLGA microcapsules that can be integrated to skin wounds through photo-inducible crosslinking.
A Schematic illustration of photo-induced crosslinking mechanism for tissue integration of hydrogel and PLGA-NB capsules. B Schematic illustration of the chemical structures of HA-NB and PLGA-NB, as well as photo-inducible integration of microcapsules with hydrogel and wounded tissue. C Structure characterization of NB, HA-NB, and PLGA-NB by 1H NMR (400 MHz).
