FABRICATION, CHARACTERIZATION, AND ANTIBACTERIAL EFFECT OF ELECTROSPUN NANOFIBERS CS/PLA/PEG LOADED WITH THE NATURAL COMPOUND CAPSAICINPham Thi Nhung1,2, Ngo Thi Phuong1, Tran Hoai Khang3, Luu Van Chinh1, Le Ngoc Hung2,4, Do Thi Thanh Huyen1, Le Minh Ha1,2*Abstract: In this paper, electrospun nanofibers composed of polymers including chitosan (CS), polyethylene glycol (PEG), polylactic acid (PLA) loaded with 12% capsaicin were prepared using electrospinning method. The morphological and chemical characteristics of the nanofibers were analyzed using a scanning electron microscope (SEM) and the Fourier transform infrared (FTIR) spectra, respectively. The obtained nanofibers were uniform, smooth with an average diameter of 269 %u00b1 54 nm.
