Abstract

Fluorescence resonance energy transfer (FRET)-based protein biosensors report intracellular molecular activities with high spatiotemporal resolution via optical signal. A critical limit for these biosensors has been the requirement of genetic encoding which makes the examination of scarce cell samples impractical. By directly delivering the protein form of the biosensor into cells using electroporation on microfluidic platform, we achieve sufficient concentration of the biosensor inside cells and observe strong FRET signal that is indicative of molecular activity. Our method does not require delivery and expression of the biosensor plasmid and thus is suitable for samples size down to ∼100 cells.
