• simultaneously via ionic interactions between the exposed functional groups of the capping agent and metal ions. This issue can be addressed using ʟ-carnosine-capped nanosilver because the interaction of ʟ-carnosine with different metal ions has already been reported [19]. The electrochemical detection of Hg2

However, silver nanoparticles with anisotropic shape were reported to have two absorption bands, namely transverse and longitudinal [24]. Furthermore, the color of the anisotropic nanosilver is different from yellow, which is also

• , in nanosilver, a dislocation loop migrates to the free surface of the particle within 0.1 s [4]. This suggests that dislocation loops and interstitials are leveled out fairly quickly in nanoparticles, making vacancies the main defects that affect the material’s properties. According to experimental
