General description

Reactive group: Carboxylic acid.

Application

CdS/ZnS or CdSe/ZnS quantum dots (QDs) with carboxylic acid in lyophilized solid form can be readily reconstituted in DI water or DMSO to any desired concentration and are very stable in most buffer solutions with a pH range of 5-10. These QDs possess a zeta potential in the -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.

The excellent optical properties of quantum dots (QDs), such as high brightness, high photostability, continuous absorption, and narrow emission bandwidth, make them ideal as optical labels to develop QD-based immunohistofluorescence (IHF) imaging for multiplexing cancer biomarker detection on formalin-fixed and

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
