- *Abstract
-
The development of fluorescent indicators for sensing membrane potential can be a challenge. Traditional methods to measure membrane potential rely on invasive electrodes, however, voltage imaging with fluorescent probes (VF) is an attractive solution because voltage imaging circumvents problems of low- throughput, low spatial resolution, and high invasiveness. Previously reported VF probes/dyes have proven useful in a number of imaging contexts. However, the design scheme for VF dyes remains elusive, due in part to our incomplete understanding of the biophysical properties influencing voltage sensitivity in our VoltageFluor scaffolds.
UC Berkeley researchers have discovered new VF dyes, which are a small molecule platform for voltage imaging that operates via a photoinduced electron transfer (PeT) quenching mechanism to directly image transmembrane voltage changes. The dyes further our understanding of the roles that membrane voltage plays, not only in excitable cells, such as neurons and cardiomyocytes, but also in non-excitable cells in the rest of the body.
