Here we present the first findings on the resonance response of DNA oligonucleotides deposited on silicon nanosandwich (SNS) and living bio-tissue to the THz irradiation that allow their identification by measuring the changes of the longitudinal conductance and the lateral voltage within frameworks of the SNS prepared in the Hall geometry. The mechanism of the THz response is discussed, with the model of the Shapiro steps related generation. The THz resonance response from living bio-tissue under the THz radiation is also applied to the definition of oncological diseases. The results obtained form the basis of the express diagnostics in practical medicine.

Measurements of the field dependences of the static magnetic susceptibility demonstrate de Haas-Van Alphen and Aharonov-Bohm oscillations at high temperatures and low magnetic fields in silicon nanosandwich structures (SNS). In the case of the deposition of DNA oligonucleotides into the edge channels of the SNS, a change in the oscillation period is observed. The possibilities of using the obtained data to identify the properties of DNA oligonucleotides are discussed. Keywords: THz radiation, DNA identification, de Haas-Van Alphen, Aharonov-Bohm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
