Abstract

Abstract
This work reports the synthesis of silver nanoparticles (AgNPs) using the leaf extract of Almond plant. Larvicidal activities of the
biosynthesized AgNPs were evaluated against the fourth instar larvae of mosquito Aedes aegypti. The biosynthesised AgNPs were
characterised using UV-Visible, Fourier Transmission Infrared Spectroscope (FTIR), Energy Dispersive X-ray Spectroscope (EDX)
and Field Emission Scanning Electron Microscope (FESEM). The absorption spectrum of the synthesized AgNPs showed a
maximum spectrum of 430 nm while FTIR analysis showed different functional groups present on the surface of the AgNPs
with broad peak between 3000 and 3800 cm-1. The FESEM showed a large number of spherically shaped nanoparticles with sizes
ranging from 8.34 to 78.96 nm. The 50% (LC50) lethal concentration of the nanoparticles after 12 h was 13.54 µg/ml. This study
showed that almond leaf can be used for synthesis of AgNPs thus adding to the available drugs that could be used in combating
multidrug resistant pathogens.
