Silver nanocubes make point-of-care diagnostics easier to
read

Engineers at Duke University have shown that nanosized
silver cubes can make diagnostic tests that rely on fluorescence
easier to read by making them more than 150 times brighter.
Combined with an emerging point-of-care diagnostic platform already
shown capable of detecting small traces of viruses and other
biomarkers, the approach could allow such tests to become much
cheaper and more widespread.
