Titanium nanoparticles phytosynthesized from Eichhornia crassipes leaf extract and their antimicrobial activity.

Abstract

AbstractIn this study, we reported an environmentally friendly technique for the synthesis of titanium nanoparticles using Eichhornia crassipes leaf extract as a non-toxic reducing agent and efficient stabilizer. Also the antimicrobial activity TiNPs against E. coli. Bacteriological test were performed on solid agar plates with different concentrations of TiNPs. On the other hand TiNPs were characterized by UV-visible spectroscopy, EDS (Dispersive Energy X-ray Spectroscopy), SEM (Scanning Electron Microscopy), and TEM (Transmission Electron Microscopy). It was found that TiNPs exhibit high crystallinity whit rutile titania structure. TEM analysis shows the nanoparticle size in the range from 22 to 44 nm, antimicrobial study was performed by plate count technique witch showed >99% mortality for E. coli bacteria studied after 24 h of incubation.
