Controlled Dual Delivery of Angiogenin and Curcumin by Electrospun Nanofibers for Skin Regeneration

In this study, we successfully fabricated a novel drug and plasmid DNA (pDNA) dual delivery system by electrospinning the dispersion composed of polyethyleneimine-carboxymethyl chitosan/pDNA-angiogenin (ANG) nanoparticles, curcumin (Cur), poly (D, L-lactic-co-glycolic acid) (PLGA), and cellulose nanocrystals (CNCs). In vitro release studies showed that the bioactivity of Cur and ANG was preserved in the nanofibers, and a sequential release...
