Quantum Dots: NIR-Emitting Quantum Dot-Encoded Microbeads through Membrane Emulsification for Multiplexed Immunoassays (Small 19/2013)

A detection platform combining NIR emitting CdSeTe/CdS/ZnS quantum dot (QD)-encoded microbeads and flow cytometry with a 488 nm laser is described on page 3327 by W. Li, K. Sun, X. Chen, and co-workers. This platform is used to conduct a 2-plex hybridization assay for hepatitis B surface antigen, hepatitis Be antigen and a 3-plex hybridization assay for hepatitis B surface antibody, hepatitis Be antibody and hepatitis B core antibody, which suggests the promising application of NIR QDencoded microbeads for multiplexed immunoassays.
