Surface plasmon-coupled directional emission based on a conformational-switching signaling aptamer

Chem Commun (Camb). 2009 Jun 14:(22):3190-2. doi: 10.1039/b823352g. Epub 2009 Apr 23.

Abstract

We have observed highly polarized and directional surface plasmon-coupled emission of a signaling aptamer due to the binding of a target thrombin with the aptamer, which induces conformational switching.
