Aplicação

CdS/ZnS or CdSe/ZnS quantum dots (QDs) with carboxylic acid in lyophilized solid form can readily be reconstituted in DI water or DMSO to any desired concentration and are very stable in most buffer solutions in the pH range of 5-10. These QDs possess zeta potential in -30 mV to -50 mV range and can easily be reacted with amine containing molecules in DMSO or water. These QDs find applications in bioimaging and biosensing.[1][2][3]

Genetically-engineered collagen peptides were assembled into freestanding films when QDs are co-assembled as joints between collagen domains. These peptide based films show excellent mechanical properties with Young's modulus of ~20 GPa, much larger than most of multi-composite polymer films and

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
