New research on materials science from Y.G. Zheng and co-authors summarized

  2008 NOV 24 - (VerticalNews.com) -- According to recent research published in the journal Advanced Materials, "Coating of quantum dots (QDs), derived from both aqueous synthesis and organometallic routes, with a crosslinked peptide sheath via mimicking phytochelatin-coated heavy metal nanoclusters in plant cells is reported."

  "This coating greatly improves the stability of QDs, while maintaining their optical properties. Coated QDs contain carboxylate and amine groups for facile conjugation with various bioprobes," wrote Y.G. Zheng and colleagues.

  The researchers concluded: "They are biocompatible and have an overall size as small as 6 nm."

  Zheng and colleagues published their study in Advanced Materials (From glutathione capping to a crosslinked, phytochelatin-like coating of quantum dots. Advanced Materials, 2008;20(18):3410+).
