Interaction of Silver Nanoparticles and Chitin Powder with Different Sizes and Surface Structures: The Correlation with Antimicrobial Activities

Figure 5

Chitins A, B, C, G-C, D, and G-D/Ag NP composites were evaluated for their bactericidal (against E. coli) activity in LB medium. The composites contained various amounts of Ag NPs in 10 mg of chitin and exhibited a strong, concentration-dependent bactericidal activity. Data are the mean ± standard deviation; . ND = not detected. Asterisks () denote statistically significant differences ( ) as determined using a two-sample t-test.
