Preparation of Size-Controlled Silver Nanoparticles and Chitin-Based Composites and Their Antimicrobial Activities
Figure 4
Size-controlled Ag NP/chitin composites were evaluated for their bactericidal (against E. coli) activities in LB medium. The composites contained various amounts of small (a), medium (b), and large (c) Ag NPs in 10 mg chitin/mL and exhibited a strong bactericidal activity in a concentration-dependent manner. Data are mean value standard deviation; . ND means “not detected.” The asterisk (*) represents statistically significant difference () using two-sample t-test.
