Researchers from Kazan Federal University Detail Findings in Colloids and Interface Science

June 3, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Colloids and Interface Science have been presented. According to news reporting originating in Kazan, Russia, by VerticalNews journalists, research stated, "The work introduces the quenching of silica coated Tb(III) complexes by merocyanine 540 (MC540) and copper ions as a tool to reveal the adsorption of phosphatidylcholine (PC) and phosphatidylserine (PS) at various PS:PC ratio onto silica nanoparticles doped with Tb(III) complex. The binding of MC540 with PC-based bilayers and copper ions with PS-based ones are the basis of their use as organic and inorganic probes to sense PS:PC ratio in silica supported mixed bilayers."

The news reporters obtained a quote from the research from Kazan Federal University, "The enrichment of mixed bilayers by PS results in the displacement of MC540 anions, while it enhances the binding with copper ions. The displacement or binding of probe ions results in the diverse luminescence response of Tb(III)-centred luminescence. The reestablishment of the steady state and time resolved luminescence is observed, when MC540 anions are applied as probes. The use of copper ions as probes results in the opposite quenching effect."

According to the news reporters, the research concluded: "The developed route enables to discriminate the formation of the phospholipids bilayers onto silica surface from those in the bulk of solution under various concentration conditions."
