METHOD AND APPARATUS FOR IDENTIFYING MOLECULAR SPECIES ON A CONDUCTIVE SURFACE

摘要

A nano-probe for performing single electron molecular orbital tunneling spectroscopy (SEMOTS) is disclosed. Unlike the conventional probes, the nano-probe is capable of obtaining highly resolved spectra of single molecule electronic structures on conductive surfaces. The increase in spectral resolution allows the unique spectrum of adsorbed molecules to be collected into a database and subsequently used to identify adsorbates on surface on unknown samples. The nano-probe can be utilized for genetic sequencing of single molecules of deoxyribose nucleic acid and other oligonucleotides based on the differences in orbital energy spectra of the nucleotide bases.
