QBO – CdSe/ZnS Quantum Dots in H2O - PBA
QBO is a group of water soluble CdSe/ZnS quantum dots with amphiphilic polymer coated with PEG and conjugated with phenylboronic acid (PBA). Their surface functional group is PBA. PBA forms favorable binding with sialic acid (SA) through common carbohydrates (mannose, glucose, galactose, and SA), which are found on the glycan structures of cell membrane surfaces, at the physiological pH of 7.4. Changes in SA expression are closely associated with various disease states such as cancer, cardiovascular and neurological diseases. QBO can specifically and efficiently label SA on living cells.

QCH- Water soluble Quantum Dots – MPA
QCH is a group of CdSe quantum dots with mercaptopropionic acid coating. Their emission efficiency is low due to organic thiol ligand. These QDs can be used for fabrication of solar cells.
