Larvicidal activity of synthesised silver nano particles from Coccinia grandis leaves extract

Abstract

The goal of the current study is to synthesise silver nanoparticles (SNPs) using Coccinia grandis leaf extract in aqueous form and assess their effectiveness against mosquito larvicidal properties. Through the use of FTIR analysis, scanning electron microscopy, and UV visible absorption, the synthesised silver nanoparticles (SNP) were identified and verified. Aedes aegypti and Culex quinquefasciatus I st to IV th in star larvae were assayed for 24 and 48 hours at different concentrations (50-250 ppm). Aqueous extracts from Coccinia grandis leaves exhibited noteworthy activity, while silver nanoparticles (SNP) demonstrated a notably greater mortality activity in Culex quinquefasciatus than Aedes aegypti larvae in the current investigation. The potential larvicidal activity of our study's Coccinia grandis leaf extract and synthesised SNPs suggests that this could be an excellent environmentally friendly method of control and protection. This is only an initial investigation into its larvicidal activity more research is required for deep insights of this formulation.

Adsorption‐Based Approaches for Exploring Nanoparticle Effectiveness in Wastewater Treatment

“…By eliminating dangerous microbes, these techniques may improve disinfection by eliminating a variety of toxins from wastewater, such as organic pollutants and heavy metals. This research provides valuable insights into the potential of cutting-edge wastewater treatment techniques to enhance the overall effectiveness of disinfection and wastewater treatment, [1,2] These studies highlight the need to find practical and long-lasting ways to deal with the increasing amount of sewage sludge. Wastewater treatment is crucial for safeguarding both human health and the environment because untreated wastewater can harbour dangerous contaminants like chemicals, bacteria, and viruses that can contaminate drinking water sources and endanger aquatic life.…”
