Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Single‐molecule GPS</bold>: 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).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1pjpmx3t" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
