Control of filariasis by silver nanoparticles: A green method for health care

The synthesis, characterization and application of green and biologically synthesized nano-materials have become an important branch of nanotechnology. In this paper, we report the synthesis of highly dispersed silver nanoparticles using a fresh leaves of Ficus religiosa(An endemic plant) extract as the reducing agent. After exposing the silver ions to leaves extract, rapid reduction of silver ions is observed leading to the formation of silver nanoparticles in solution. UV-VIS spectrum of the aqueous medium containing silver nanoparticles showed absorption peak at around 470 nm. Transmission Electron Microscopy (TEM) micrograph analysis of the silver nanoparticles indicated that they were well-dispersed and ranged in size 30-40nm. The aspects of formation of a specific geometry i.e. spherical shape played a key role in the efficacies against the different larval stages of vectors of Filariasis Culex quinquifasciatus. The effect of spherically AgNPs with the Ficus the formation of silver has also been investigated. The presence of nanosilver has been carried out with the Micro-scan reader. The validation micrographs of the silver nanoparticles have been evaluated through the Transmission Electron Microscope (TEM). The effect of concentrations with response to time, temperature and pH has been studied with the help of Micro-scan reader and the microstructure was analyzed by TEM. In conclusion we observe that geometry of the synthesised nanoparticle played a very crucial role which subsequently affected the efficacies of synthesised nanosilver against the mosquito species Culex quinquifasciatus.
