RPOC technology
The next generation optical regulation
RPOC stands for Real-Time Precision Opto-Control. It enables unprecedented flexibility, spatial precision, and chemical selectivity for regulating chemical processes within live biological samples.
RPOC can be integrated into any custom laser-scanning microscopes or stage-scanning microscope platforms.
Sentry IV is our most advanced RPOC system based on confocal fluorescence. It offers state-of-the-art capabilities for precisely modulating biological samples with light and simultaneous monitoring their responses.

RPOC prototype used by our collaborator
“RPOC’s ability to image and stimulate at the same time, especially for in vivo wounding and optogenetic stimulation, enables a temporal resolution which is irreplaceable for our studies of early tissue-scale wound response.”
