Dissolution of Silver Nanowires and Nanospheres Dictates Their Toxicity to Escherichia coli
Figure 2
Scanning electron micrographs (SEM), EDX mapping, and UV-vis spectra of the Ag nanowires (NWs) and Ag nanospheres. (a) and (c) SEM micrographs of Ag NWs, (b) and (d) SEM micrographs of Ag nanospheres; note different magnifications; scale bars are indicated. Insets in (c) and (d) show EDX mapping. (e) UV-vis spectrum of Ag NWs and (f) UV-vis spectrum of Ag nanospheres. Maximum absorbance values are shown in (e) and (f).
