DNA Monofunctionalization of Quantum Dots

Abstract

Dots as pure as the driven snow: A method to purify streptavidin-coated quantum dots functionalized with a single short DNA duplex from an inhomogeneous population is presented. A high percentage (∼86 %) of the monofunctionalized quantum dots present in the original sample are recovered. Hybridization of the attached DNA after purification is demonstrated.
