Popis: Nanodisc technology was implemented as a platform for voltage nanosensors. A FRET-based voltage sensing scheme employing fluorescent nanodiscs and the hydrophobic ion dipicrylamine (DPA) was developed and utilized to optically record membrane potentials on the single nanodisc level. Ensemble- and single- nanosensor recordings were demonstrated for HEK293 cells and primary cortical neuron cells. Conjugation of nanodiscs to anti-GABA-A antibodies allowed for site specific membrane potential measurements from post synaptic sites.
