Single molecule optical spectroscopy in solid-state nanopores in a transmission-based approach

摘要

Methods and apparatus in the field of single molecule sensing are described, e.g. for molecular analysis of analytes such as molecular analytes, e.g. nucleic acids, proteins, polypeptides, peptides, lipids and polysaccharides. Molecular spectroscopy on a molecule translocating through a solid-state nanopore is described. Optical spectroscopic signals are enhanced by plasmonic field-confinement and antenna effects and probed in transmission by plasmon-enabled transmission of light through an optical channel that overlaps with the physical channel.
