Selective functionalization of semiconductor quantum dots with short peptides and integrins of cancer cells for biophotonic applications [link]Paper  abstract   bibtex   
We discuss our results on study of structural properties of the nanoscale integrated colloidal semiconductor quantum dots (SQDs) such as CdS and ZnS-capped CdSe conjugated with biomolecules such as short peptides and integrins of cancer MDA-MB- 435 cells for biomedical applications. We study chemically prepared CdS SQDs functionalized with peptides composed of the following aminoacid chains: CGGGRGDS, CGGGRVDS, CGGIKVAV, and CGGGLDV. The effective diameter of the CdS SQDs is 3 nm. The cysteine (C) aminoacid links to CdS SQDs via the thiol link, the GGG sequences of glycine (G) amino acid, provide a spacer in the amino acid chain. The RGDS, RVDS, IKAV, and LDV sequences have selective affinities to specialized transmembrane cellular structures known as integrins of neurons and MDA-MB-435 cancer cells, respectively. We also studied a role of water and other bioenvironments in stability, surface properties, dynamical and structural characteristics of these systems.
