A plasmonic patch that amplifies fluorescing signals could have a significant impact on life science research.
Using fluorescent markers to track molecular biological activity is a common research technique, but the signals can be difficult to detect in dim light. To overcome that limitation, teams from Washington University and the Air Force Research Laboratory created an elastic material embedded with gold nanorods that can amplify fluorescence intensity by up to 100 times. The patch is placed over a sample prepared in the standard way, with no change in testing protocol, whereupon it will concentrate the light of the fluorescing molecules to make them more easily detected.
