Data on Organosilica Reported by Researchers at Pusan National University (Fluorescent mesoporous organosilicas for selective monitoring of Hg2+ and Fe3+ ions in water and living cells)

By a News Reporter-Staff News Editor at Science Letter -- A new study on Organosilica is now available. According to news reporting originating from Yangsan, South Korea, by NewsRx correspondents, research stated, "A new fluorescent mesoporous organosilicas bearing ethidium bromide in the framework was conveniently synthesized using 3-aminopropyltriethoxysilane as bridging organosilane functionality. Powder X-ray diffraction, N-2 sorption, transmission electron microscopy and scanning electron microscopy, and UV-visible absorption and fluorescence spectroscopy have been employed to characterize the materials."

Our news editors obtained a quote from the research from Pusan National University, "This material showed a selective monitoring of Hg2+ and Fe3+ ions with fluorescence quenching and visible color transition over a wide range of tested metal ions, which is due to the selective interactions of Hg2+ and Fe3+ ions with integrated functional groups at its pore wall framework. The experimental measurements reveal that the mesoporous organosilica material shows Hg2+ and Fe3+ ion selectivity upon addition of various concentrations of other competitive metal ions."

According to the news editors, the research concluded: "Thus, the synthesized mesoporous organosilicas could monitor Hg2+ and Fe3+ ions in water and biological cells even in the trace amount."
