Researchers detail in 'Detection of pathogens using luminescent CdSe/ZnS dendron nanocrystals and a porous membrane immunofilter,' new data in biosensors. According to recent research from the United States, "A biosensor system for detection of pathogens was developed by using CdSe/ZnS core/shell dendron nanocrystals with high efficiency and stability as fluorescence labels and a flowing chamber with a microporous immunofilter.
