Abstract
Terahertz (THz) spectroscopy is sensitive to probe several aspects of biological systems. In THz frequency, electrically controllable Drude-like intraband absorption makes graphene a promising platform for building graphene-based optoelectronic devices such as THz biosensor. In this work, BSA protein thin films were spin-coated and incubated on single-layer graphene. IR lasers with different power were used as the pump light to stimulate the sandwich-like sample respectively. The graphene monolayer complex conductivity was calculated using the transmission method. The novel optical properties of single-layer graphene and BSA protein on graphene in the THz range will be discussed in this paper.
