'Plasmonic' Medical Diagnostic Patch Boosts Brightness by 100 Times

Fluorescence-based biosensing and bioimaging technologies are widely used in research and clinical settings because they are convenient to use, but they suffer from poor sensitivity. Researchers from Washington University have developed a high-tech fix that utilizes metal nanostructures to increase the fluorescence intensity by 100 times in these diagnostic tests. It’s a cheap and easy solution to what has previously been a vexing diagnostic problem. The "plasmonic patch" is a flexible piece of film about a centimeter square, embedded with nanomaterials. All a researcher or lab tech needs to do is prepare the sample in the usual method, apply the patch over the top, and then scan the sample as usual.
