Application

Streptavidin has high binding affinity to biotin or biotin-containing molecules such as proteins, peptides, polysaccharides, oligonucleotides. Streptavidin functionalized quantum dots offer an simple and universal method to conjugate those biotinylated molecules to quantum dots for downstream applications such as flow cytometry, Westen blot, microplate assay, fluorescent imaging with microscope for slide-based assay , microarray assay, bead-based assay, fluorescent sensing.The advantages of using quantum dots as fluorophores include high brightness, narrow and symmetric emission, resistant to photobleaching, etc. These unique features make quantum dots ideal optical probes for highly sensitive multiplexing applications.

Articles

Dr. Delehanty and researcher introduce recent advances in the use of cadmium-free quantum dots for bioimaging. Focus is placed on strategies that have emerged in the last five years for design, synthesis, and surface modifications of non-Cd quantum dots (QDs) for bioimaging and sensing applications.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
