A facile method for synthesis of biostabilized silver nanoparticles using Eichhornia crassipes (Mart.) Solms (water hyacinth).
Eichhornia crassipes (Mart.) Solms (water hyacinth) is an invasive free-floating perennial hydrophyte, which causes water pollution. It blocks ponds, rivers and water bodies obstructing water transport, irrigation and hydropower systems. It reduces biodiversity and provides favorable breading zones to disease-causing vectors. In the present study, aqueous extract of the E. crassipes plant was used for the biological synthesis of stabilized silver nanoparticles, which are used to have important applications in medicine, biopharmaceuticals, electronics and catalysis. The nanoparticles were characterized using UV-Vis spectrophotometry, X-ray diffraction (XRD), Field emission gun-Scanning electron microscopy (FEG-SEM), Energy dispersive analysis of X-rays (EDAX) and Fourier transform infrared spectroscopy (FTIR). The nanoparticles demonstrated antimicrobial activity against selected Gram positive and negative bacteria.
