Quantitative determination of carbohydrate antigen 153 (CA153) in human serum plays an important role in early diagnosis of breast cancer. In this work. a highly sensitive and selective biosensor for CA153 detection was developed based on a fluorescent resonance energy transfer (FRET) strategy. in which near-infrared (NIR)-excitable upconversion nanoparticles (UCNPs) and the commercia... https://www.jmannino.com/mega-pick-Superman-Clark-Big-Bang-Lite-Headband-amazing-offer/
