چکیده
Smart antibacterial materials capable of releasing antibiotic drugs upon exposure to external triggers are highly desired for various medical applications. Herein, the fabrication thermosensitive drug-loaded core−shell nanofibers using electrospinning technique combined with in situ UV photopolymerization is reported on. The method used shaping core structure comprising biodegradable polymer polycaprolactone (PCL). PCL fibers coated temperature-responsive poly-N-isopropylacrylamide (PNIPAM) via a process that allows precisely control shell thickness as verified by transmission electron microscope (TEM) analysis. temperature-dependent switchable wettability prepared investigated and visualized though water contact angle measurements below above lower critical solution temperature. Loading drug doxycycline hyclate (Doxy) results drug-encapsulating fiber meshes allow diffusion molecules through PNIPAM manner. activity examined Gram-negative Escherichia coli (E. coli) well Gram-positive Staphylococcus aureus (S. aureus) bacteria. demonstrate high suitability biocompatible electrospun PCL/PNIPAM carriers temperature-sensitive release behavior.

A promising therapy for retinal diseases is to employ biodegradable scaffolds to deliver retinal progenitor cells (RPCs) for repairing damaged or diseased retinal tissue. In the present study, cationic chitosan-graft-poly(ɛ-caprolactone)/polycaprolactone (CS-PCL/PCL) hybrid scaffolds were successfully prepared by electrospinning. Characterization of the obtained nanofibrous scaffolds indicated ...
