Nano-crystalline ZnO has been studied with perturbed angular correlation using 111mCd, implanted at ISOLDE/CERN and X-ray diffraction using Rietveld analysis. The data show a gradual increase in the crystal size and stress for a sample annealed at 600 °C, and reaching nearly properties of standard ZnO with tempering at 1000 °C. The perturbed angula...
Positron lifetime spectroscopy (PAL), Doppler broadening (DB) as well as
coincidence Doppler broadening (CDB) spectroscopy of a new variety of Folic
acid (FA) capped zinc oxide nano-particle samples has been performed at room
temperature. The results show interesting patterns of observation, hither-to
unobserved in ZnO wurtzite crystalline samples,...
The focus of this article is based on the aqueous dispersed state properties
of inorganic ZnO nanoparticles (average size lessthan or equal to 4 nm), their
surface modification and bio-functionalization with folic acid at physiological
pH ~ 7.5, suitable for bio-imaging and targeted therapeutic application. While
TEM studies of the ZnO nano-crystal...
The structural characterization of sol-gel based nano crystalline ZnO
material is being reported as we observe several previously unreported
structural aspects following a sequence of annealing stages. As-grown samples
were characterised by Fourier Transform Infrared Spectroscopy (FTIR). Chemical
purity of the nano-grains and their crystallinity ha...
ZnO nanoparticles (grown in the template of folic acid) are biologically useful, luminescent material. It can be used for multifunctional purposes, e.g., as biosensor, bioimaging, targeted drug delivery and as growth promoting medicine.
Sol-gel chemical method was used to develop the uniform ZnO nanoparticles, in a folic acid template at room tempe...

... using sol-gel method has two intense emission bands in the up-conversion emission spectra, 542 nm green and 660 nm red 23 . Functionalized ZnO nanostructures with FA achieved stable and dispersed aqueous ZnO NPs 24 . FA is one of the vitamin B family and is an important for the synthesis and repair of DNA and other genetic materials, and it is necessary for cells to divide. ...

... The sol-gel method is an attractive preparation method that can control the product purity, with a high surface area and the products can be prepared at a low crystallization temperature, which implies low cost [12,13]. Sol-gel technique makes molecular precursor transformation onto a stable condensed oxide network that is explained by several stages, hydrolysis, and polymerization for the formation of the sol precursor followed by condensation, dehydration, nucleation, and growth, which is achieved through annealing [14,15]. ...
