Fluorescent protein biosensors are typically implemented via genetic encoding which makes the examination of scarce cell samples impractical. By directly delivering the protein form of the biosensor into cells using electroporation, we detected intracellular molecular activity with the sample size down to ~100 cells with high spatiotemporal resolution.
