Quaternary ammonium salt containing antibacterial nanofibers

, 2021
Different techniques have been used in the preparation of nanoscale structures with a high surface area such as biomaterial scaffolds for vascular grafts, wound dressings or air purifying filters. In the present study, an antibacterial agent, such as cethyltrimethyl ammonium bromide(CTAB) and cetylpyrridinum chloride (CPC) have been incorporated into ...
