Quantum Tunnelling Combined With Dielectrophoresis… Single-Molecule Detection Events Amplified Up to 100,000-Fold
Researchers at Zhejiang University in China and Imperial College London in the UK built standalone tunnelling electrodes with an average gap of 1.6 nm at the tip of a nanopipette, and used them to identify single nucleotides and proteins electrically. By combining the probes with dielectrophoretic (DEP) trapping, which...
