Water‐Soluble DNA‐Wrapped Single‐Walled Carbon‐Nanotube/Quantum‐Dot Complexes

Abstract

A new nanomaterial conjugation technique is presented to effectively bind semiconductor quantum dots (QDs) onto single-walled carbon nanotubes (SWCNTs) via covalent amidation, employing single-stranded DNA oligonucleotides as linkers (see schematic and AFM image). This technique provides a measurement platform for the study of their interactions involving photoinduced charge transfer between QDs and SWCNTs at the nanoscale.
