Comparative study on larvicidal activity of green synthesized silver nanoparticles and Annona glabra (Annonaceae) aqueous extract to control Aedes aegypti and Aedes albopictus (Diptera: Culicidae)


2020 The present study reports mosquito larvicidal potential of green synthesized silver nanoparticles by using Annona glabra leaves (An-AgNPs). Synthesized An-AgNPs were characterized by Ultraviolet-Visible spectroscopy (UV-VIS), Scanning Electron Microscopy (SEM), Dynamic Light Scattering (DLS) technique and Fourier transform infrared spectroscopy (FTIR).

Antibacterial effect of Ag-doped TiO2 nanoparticles incorporated natural rubber latex foam under visible light conditions

Iranian Polymer Journal

2015 Ag-doped TiO2 nanoparticles (Ag-TiO2 NPs) incorporated into natural rubber latex foam (NRLF) showed enhanced antimicrobial activities under visible light. Synthesis of Ag-TiO2 NPs and their incorporation into NRLF are investigated in this paper.

Imparting antimicrobial properties to natural rubber latex foam via green synthesized silver nanoparticles

Journal of Applied Polymer Science

2013 The green synthesis of silver nanoparticles (AgNPs) in centrifuged natural rubber latex (NRL) by in situ reduction of silver nitrate by NRL is described. The synthesis of AgNP within NRL was successfully carried out without the addition of any reducing agent or stabilizers. The modified AgNP incorporated with centrifuged NRL (GAgNP_NRL) was used to make NRL foam (NRLF) by the Dunlop production method.
