Abstract
Nanosilver coated bacterial cellulose nanofiber and a method of producing the nanosilver coated bacterial cellulose nanofiber. The nanosilver coated bacterial cellulose nanofiber is produced by preparing a suspension of bacterial cellulose fibers, oxidizing bacterial cellulose fibers; adding the thio- group to the polymer backbone; reacting the resulting product with silver proteinate and enhancing the nanosilver particle size. The nanosilver coated bacterial cellulose nanofibers exhibit antimicrobial properties.
