Quantum‐Dot Fluorescence Lifetime Engineering with DNA Origami Constructs

Abstract

Single-molecule GPS: The average photon count rate and lifetime of a quantum dot (Qdot) have been controlled by varying the geometrical configuration of Qdot–gold nanoparticle (AuNP) conjugates on DNA origami. With a 3D real-time single-molecule tracking system, which allows the DNA templates to be kept in their native state in solution, the influence of AuNPs on the Qdot lifetime is determined (see picture).
