TPP ionically cross-linked chitosan/PLGA microspheres for the delivery of NGF for peripheral nerve system repair

To manage the discharge of nerve progress issue (NGF) within the injured peripheral nerve, NGF-loaded chitosan/PLGA composite microspheres ionically cross-linked by tripolyphosphate (TPP/Chitosan/PLGA-NGF) had been ready. The encapsulation effectivity of NGF ranged from 83.4 ± 1.5 % to 72.1 ± 1.6 % with TPP concentrations from 1 % to 10 %. Zeta potential and FT-IR
