Investigators from Chungnam National University Zero in on Biomolecular Research

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Life Science Research are presented in a new report. According to news reporting from Taejon, South Korea, by NewsRx journalists, research stated, "A new photochromic diarylethene derivative bearing rhodamine 6G dimmer as a fluorescent molecular probe is designed and synthesized successfully. All the compounds are characterized by nuclear magnetic resonance and mass spectrometry."

The news correspondents obtained a quote from the research from Chungnam National University, "The bisthienylethene-rhodamine 6G dyad exhibit excellent phtochromism with reversibly color and fluorescence changes alternating irradiation with ultraviolet and visible light. Upon addition of Hg2+, its color changes from colorless to red and its fluorescence is remarkably enhanced. Whereas other ions including K+, Na+, Ca2+, Mg2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Mn2+, Pb2+, Ni2+, Fe3+, Al3+, Cr3+ and so on induce basically no spectral changes, which constitute a highly selective and sensitive photoswitchable fluorescent probe toward Hg2+."

According to the news reporters, the research concluded: "Furthermore, by means of laser confocal scanning microscopy experiments, it is demonstrated that this probe can be applied for live cell imaging and monitoring Hg2+ in living lung cancer cells with satisfying results, which shows its value of potential application in environmental and biological systems."
