Detecting Single-Nucleotides by Tunneling Current Measurements at Sub-MHz Temporal Resolution

Label-free detection of single-nucleotides was performed by fast tunneling current measurements in a polar solvent at 1 MHz sampling rate using SiO2-protected Au nanoprobes. Short current spikes were observed, suggestive of trapping/detrapping of individual nucleotides between the nanoelectrodes. Th...
