Abstract

The exploration of methods to produce biomaterials with antibacterial properties in ultra-small scales is of great scientific and technological interest. Here, we reported a microfluidic spinning approach to prepare a novel film combined with konjac glucomannan (KGM), polyvinylpyrrolidone (PVP), and epigallocatechin gallate (EGCG). The film was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis. This film was transparent, orderly, thermally stable, and uniform in size, with an average width less than 1 μm. Also, the film exhibited excellent antibacterial efficiency (97.1% against E. coli, 99.7% against S. aureus, 97.3% against S. enterica and 99.9% against B. subtilis) in our antibacterial test. In addition, the film promoted wound healing with the advanced development of neovascularization and hair follicles. This strategy provides a facile and green pathway for the construction of biomaterial films for medical applications.
