We developed membrane voltage nanosensors which are based mostly on inorganic semiconductor nanoparticles. We offer right here a feasibility research for his or her utilization. We use a rationally designed peptide to functionalize the nanosensors, imparting them with the power to self-insert right into a lipid membrane with a desired orientation. As soon as inserted, these nanosensors may sense membrane potential by way of the quantum confined Stark impact, with a single-particle sensitivity. With additional enhancements, these nanosensors may doubtlessly be used for simultaneous recording of motion potentials from a number of neurons in a big discipline of view over a protracted period and for recording electrical indicators on the nanoscale, corresponding to throughout one synapse.
