  • Title: Resonance Energy Transfer between protein and rhamnolipid capped ZnS quantum dots: application in in-gel staining of proteins.
    Author: Janakiraman N, Mohan A, Kannan A, Pennathur G.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2012 Sep; 95():478-82. PubMed ID: 22580141.
    Abstract:
    The interaction of proteins with quantum dots is an interesting field of research. These interactions occur at the nanoscale. We have probed the interaction of Bovine Serum Albumin (BSA) and Candida rugosa lipase (CRL) with rhamnolipid capped ZnS (RhlZnSQDs) using absorption and fluorescence spectroscopy. Optical studies on mixtures of RhlZnSQDs and proteins resulted in Förster's Resonance Energy Transfer (FRET) from proteins to QDs. This phenomenon has been exploited to detect proteins in agarose gel electrophoresis. The activity of the CRL was unaffected on the addition of QDs as revealed by zymography.
