Abstract
This work has shown a green rapid biogenic Synthesis of Oscilatoria sancta freshwater micro algae aqueous extraction of silver nanoparticles (AgNPs). Surface plasma resonance (SPR) using 426 nm of UV‐–visible spectrophotometers has proven the production of AgNPs. This shows that ions (Ag+) are reduced to silver (Ago), which imply silver nanoparticles production. Additors of bio-synthesis and physio-chemical characterization of AgNPs were also diverse unique instruments as FT-IR, XRD, FESEM and HRTEM. The bioactive compounds contain aqueous extract from micro algae that may be used largely for the reduction and capping of AgNPs. Defined and quantified silver nanoparticles of 24 to 34 nm in size. The nanoparticles have a face-central cubic structure (FCC) crystallised. Synthesizing action of O. sancta algae aqueous extract produced AgNPs was evaluated against 4th instar larva of A. aegypti (dengue) and A. stephensi for their larvicidal activity (malaria). The results show that synthesized AgNPs have the potential to be utilised to manage A. aegypti and A. stephensi as excellent environmentally friending resource.
