An Insight into the Insecticidal Activity of Green Synthesized Silver Nanoparticles

Abstract

Nanotechnology is an interdisciplinary science that focuses on developing various nanoparticles. Silver nanoparticles (AgNPs) have a wide variety of potential uses that emerge from their unconventional properties. Research on green synthesis of AgNPs has gained a lot of attention because of the drawbacks associated with the chemical synthesis process, which include high energy consumption, the high toxicity of solvents, and severe pollution. The green synthesis of AgNPs involves the reduction of Ag⁺ in AgNO₃ to the nanoscale silver using fungi, Waste products, bacterial culture, and plant extract as reductants or stabilizers. The manufacture of AgNPs from plant extract is a cheap and eco-friendly, and time-efficient approach in which secondary metabolites in plant extract, act as both reducing and stabilizing agents. Due to the outburst of mosquitoes, people are currently suffering from dengue, and malaria, and increased utilization of pesticides are affecting crops. This review focuses on the green synthesis of AgNPs and their insecticidal properties. Additionally, it contrasts effective synthesis techniques using environmentally friendly approaches, providing an option for choosing the best way for AgNPs synthesis. The green synthesized AgNPs can induce mortality, virtually in all stages of mosquitoes, starting from the larval stage to the adult stage. This review covers, for the first time, the importance of green-synthesized AgNPs and their efficient insecticidal activity.
