A soft strategy for covalent immobilization of glutathione and cysteine capped quantum dots onto amino functionalized surfaces

A novel strategy for immobilization of CdTe quantum dots (QDs) onto amino functionalized solid supports was developed. QDs capped with compounds holding an amino group were covalently bonded to the substrate under mild reaction conditions, exhibiting great stability and strong luminescence.
