An Acousto-Electric Nanobiosensor
A technology is developed that uses two multiscale structures on a single crystal piezoelectric substrate of lithium niobate. A system of counter-pin electrodes for an acoustic delay line operating in the 2–3 MHz range is formed via photolithography. The system is combined with nanotransducers 60–80 nm in size, produced by means of negative electron-beam nanolithography.
