UV-Vis spectra and digital photographic images of AgNP. (A) UV-Vis spectra of AgNP: spectrum 1A-A with surfactant SDS, spectrum 1A-B with surfactant TX-100, spectrum 1A-C without any surfactant, and spectrum 1A-D is for pure Lycopersicon esculentum extract. (B) UV-Vis spectra of AgNP at different compositions of Lycopersicon esculentum extract. (C) UV-Vis spectra of AgNP with varying concentrations of silver nitrate (a) at 3 × 10−3 M, (b) at 1 × 10−2 M, and (c) at 5 × 10−2 M using 1:1 extract composition and 3 × 10−3 M SDS solution in each case. (D) Digital photographic images of AgNP produced from different concentrations of silver nitrate.
