The Role of Peptides in Nanotechnology
The integration of peptides is what transforms a raw semiconductor into a functional tool. In my review of current methodologies, it is clear that peptides have been recently utilized to improve QD solubility in aqueous solution, a critical hurdle for any biological or chemical application.
Beyond solubility, peptide-functionalized quantum dots (QDs) allow for specific surface chemistry modifications. I have observed that quantum dots (QDs) are loaded with a series of peptides to achieve targeted binding. This is often accomplished through self-assembled luminescent semiconductor quantum dot (QD) - peptide bioconjugates, which provide a stable bridge between the inorganic core and the target molecule.
