Abstract: Embodiments of the present disclosure relate to a violacein-polymer composite nanofibrous antimicrobial membrane and a method for manufacturing same, wherein the membrane comprises violacein having antimicrobial efficacy against methicillin-resistant Staphylococcus aureus (MRSA) caused by resistance to antibiotics and is formed such that one-dimensional nanofibers are three-dimensionally entangled, and can be used as an antimicrobial membrane for preventing and treating MRSA infections. Specifically, a solution in which violacein is uniformly mixed is prepared by dissolving a large amount of violacein in a solution with a polymer dissolved therein, and the solution is subjected to an electrospinning process to synthesize a nanofibrous membrane in which violacein is uniformly included inside/outside nanofibers without agglomeration. Thus, this is different from existing methods for applying a material to the surface of fibers.
