Figure 1From: Development of antimicrobial biomaterials produced from chitin-nanofiber sheet/silver nanoparticle composites Absorption of Ag NPs to ANSF. (A) The UV-visible absorption spectrum of Ag NPs. The peak of absorbance at the wavelength of 390.5 nm is indicated. The inset figure is the particle size distribution histogram of the Ag NPs. (B) TEM micrograph of Ag NPs. Scale bar represents 50 nm.Back to article page
