Photocaged FRET nanoflares for intracellular microRNA imaging†
Abstract
In 2015, we proposed FRET nanoflares for intracellular molecular (RNA, H+, and K+) detection. To improve detection accuracy and achieve on-demand sensing, herein, we developed photocaged FRET nanoflares for spatiotemporal microRNA imaging in living cells. In other words, the probes will not work until they are exposed to UV light.
