제목 Application of Pristine Nitrogen and Sulfur Doped Carbon Quantum Dots for Detection of Glutathione and Reduction of Nitric Oxide in LPS induced Microglial cells
초록 Glutathione (GSH) , a tripeptide and a potent anti-oxidant has been expressed in the cells and is involved in diverse biomedical reactions. However, under certain disease conditions like cancer, their levels are elevated in the cells resulting in abnormal cellular activity. Here we developed nitrogen and sulfur doped pristine carbon quantum dots (CQDs) as a novel biosensor for GSH detection. The developed CQDs demonstrated excitation independent emission, indicating that the fluorescence from CQDs is resulted from surface functional groups. The fluorescence of CQDs were selectively reduced only in the presence of GSH. Interestingly, the developed CQDs reduced the levels of nitric oxide (NO), a potent pro-inflammatory cytokine in the LPS induced microglial cells. The results indicate a 50% reduction in the NO production when the cells were incubated with CQDs. These results demonstrate CQDs as potent biological nanomaterials for diverse biomedical applications.
