Biomolecule sensing using low energy terahertz photons exploiting nano-slot resonance and two-dimensional materials

Abstract

We performed terahertz time-domain spectroscopy for discrimination of biomolecules using absorption enhancement on a graphene-hybridized nano-slot device. The terahertz sensing device shows noticeable signal change with different trends for different nucleotides even in femto-mole level. ？ 2019 The Author(s)
