Eco-friendly, nontoxic, inexpensive, abundantly available
hitherto unreported Eclipta prostrata leaf extract is used for the biosynthesis of titanium
dioxide nanoparticles (TiO2 NPs). The TiO2 NPs were characterized by FTIR, XRD, AFM and FESEM
analysis. FTIR peak implicated the role of carboxyl group O-H stretching amine N-H stretch in the
formation of TiO2 NPs. XRD characterized in crystallographic plane of rutile phase. AFM showed
uneven surface morphology which indicates the presence of both individual and agglomerated
nanoparticles. FESEM analysis showed shape in spherical clusters, quite polydisperse and it
ranges in size from 36 to 68 nm with calculated average size of 49.5 nm. In this paper, we have
demonstrated a novel biological route for the synthesis of TiO2 NPs. (c) 2011 Elsevier B.V. All
