Antibacterial Properties of Nanosilver PLLA Fibrous Membranes
Figure 4
SEM images magnified Staph. on PLLA and Ag/PLLA fibrous membrane 20 thousand times (20 kV). (1) The number of Staph. on PLLA membranes was more than that on the Ag/PLLA membrane. (2) Staph. on PLLA membrane had smooth surface, while the ones on Ag/PLLA membrane were not very smooth.
