Aim: To synthesize biocompatible nanoparticles of FAp co-doped with Yb/Er and Nd/Yb for bioimaging applications. Methods: Yb/Er FAp and Nd/Yb FAp was synthesized using microwave assisted wet precipitation and hydrothermal method respectively. Trisodium citrate was used as an organic modifier for the synthesis and then subjected to heat treatment for optical activation. For optical studies, Yb/Er FAp system was excited Read More

Background: Fluorescence based bioimaging is one of the widely used method for obtaining imperative information on life processes. Objective: Within the expansive spectrum of fluorescent agents being investigated, the trivalent Lanthanide (Ln) ion based nanoparticles have attracted attention due to their intrinsic luminescence property. Methods: Here we report a modified sol gel assisted synthesis of Europium (Eu) an Read More

Background: Recently, great importance has been devoted to borate glass systems doped with rare-earth ions because of their unique peculiar properties in the field of photonics for optical applications. Objective: The purpose of the present study is to investigate the effect of concentration of Sm3+ ions on the luminescence properties of lead fluoroborate glasses through the energy transfer mechanism. Materials and Metho Read More

Background: Of-late researches in colloid chemistry are becoming increasingly important in various branches of chemistry, industry, medicine and allied fields. Copper surfactants derived from various edible oils provide an interesting area of investigation pertaining to its fundamental information regarding their colloid-chemical behaviour. Copper (II) soaps and their urea complexes in polar and non-polar solvents have Read More

Aims: In this investigation, we used accurate mass high-resolution gas chromatography mass spectrometry to study the gas phase carbocations rearrangements and fragmentation of toluene and halo-toluenes as well as their deuterium labeled compounds. Objective: Accurate mass of selected ions from ionization of toluene and related compounds revealed that the initially formed radical cation C7H8 +. does not rearra Read More

Background: The metal ions play a vital role in a large number of widely differing biological processes. Some of these processes are quite specific in their metal ion requirements. In that only certain metal ions, in specific oxidation states, can full fill the necessary catalytic or structural requirement, while other processes are much less specific. Objective: In this paper we report the binding of Mn (II), Ni (II) and Co (II) wit Read More
