In this study, water soluble CdTe QDs of different emission wavelengths were prepared. Microwave synthesis was used to prepare CdTe QDs coated with mercaptopropionic acid (MPA). MPA ensures biocompatibility and good water solubility of QDs. Therefore QDs can be used directly in bioanalytics. Further, QDs modified with biotinylated glutathione (GSH) were prepared. In this case mercapto group (--SH) ensures a bonding of GSH to QDs surface and biotin serves as high specific linker for streptavidin, avidin or neutravidin modified analyte. Finally, peptide mediated immuno-quantum dots were prepared. CdTe QDs were coated with heptamer HWRGWVC which is able to bind Fc region of human immunoglobulin G.
