THz signatures of DNA in nanochannels under electrophoretic control

Abstract

During the past several years we have utilized our nanofluidic-chip technology and high-resolution frequency-domain THz spectroscopy to detect absorption signatures in biomolecules and bioparticles of various types, especially the nucleic acids. Some of the signatures have been surprisingly narrow (<; 20 GHz FWHM), leading to the hypothesis that the… (More)
