title: Ni-nitrilotriacetic acid-modified quantum dots as a site-specific labeling agent of histidine-tagged proteins in live cells.
abstract: Ni-nitrilotriacetic acid (NTA) functionalized CdSe/ZnS quantum dots (QDs) were exploited as a site-specific labeling agent of histidine-tagged biomolecules in live cells; the QDs were found to be water-soluble, aggregation free and stable for several months.
