A phenomenological electromagnetic theory of CNT-DNA metabiomaterials for applications to biosensing and DNA sequencing

We model DNA-wrapped carbon nanotubes (CNTs) as loaded conducting thin-wire antennas and use MoM to solve for currents induced in hybridized CNT-DNA samples. The coupling between CNT and DNA is phenomenologically treated as a “DNA impedance perturbation” and is inserted into the CNT MoM formulation. The model is valid for arbitrary shaped CNT-DNA geometries and is expected to be accurate for low, RF, and optical frequencies. We utilize the EM model to propose a machine learning framework that can be deployed for electromagnetic DNA sequencing and biosensing.
