Application

Highly purified CdS/ZnS quantum dots with oleic acid surface ligand contain extremely low free organic ligands and impurities. They are well suited for display, solid state lighting, and solar cell applications. They can be used as electroluminescence emitter in quantum dots based LEDs or embedded in polymer matrix as the backlight of LCD display. CdSe/ZnS quantum dots in solid form can be dispersed in most non-polar organic solvents such as toluene, chloroform, and hexane.

Caution

Do not freeze the material.

Epidermal growth factor receptor (EGFR) targeted nanoparticle are developed by conjugating a single-chain anti-EGFR antibody (ScFvEGFR) to surface functionalized quantum dots (QDs) or magnetic iron oxide (IO) nanoparticles. The results show that ScFvEGFR can be successfully conjugated to the nanoparticles
