Soluplus Graft Copolymer: Potential Novel Carrier Polymer in Electrospinning of Nanofibrous Drug Delivery Systems for Wound Therapy
Figure 3
Representative SEM micrographs of the electrospun nanofibers of PCL-PVAc-PEG graft copolymer (Soluplus) loaded with a model drug, piroxicam (PRX). (a) SEM micrograph showing the nanomat with 3D layered fiber mesh structure, nonwoven pattern, and the absence of beads; (b) SEM micrograph showing some individual nanofibers with a fiber thickness over 2 μm. Magnification: 20,000x.
