Preparation and antibacterial activity of silver nanoparticles impregnated in bacterial cellulose
(Associação Brasileira de Polímeros, 2010-01-01)
A simple method was developed to load a large amount of silver nanoparticles into bacterial cellulose (BC) produced by Gluconacetobacter xylinus in a controlled manner. Due to the high electron-rich oxygen density in the ...
