Green synthesis of silver nanoparticles from leaf extract for the detection of aminoglycoside antibiotics and other applications.

Antibiotics of aminoglycoside (AMG) class, such as streptomycin (STR), have been widely used to treat infectious diseases caused by Gram-negative bacteria in livestock and humans. In this study, a selective and sensitive colorimetric probe for the determination of STR was proposed based on eco-friendly green synthesized AgNPs from the leaf extract of . The mechanism for the detection of STR is based on the electrostatic interaction of opposite charges between negatively charged silver nanoparticle- leaf (AgNP-MZL) and STR, causing an aggregation-induced characteristic shift of the SPR band (from 390 nm to 570 nm wavelength) of AgNP-MZL.
