Terahertz meta-biosensor for bovine serum albumin sensing based on electromagnetic-induced transparency-like effect.

ABSTRACT:

Background

Bovine serum albumin (BSA) sensing plays an important role in the diagnosis of various diseases, yet, there is still a lack of a cost-effective terahertz solution. Terahertz metamaterials based on electromagnetically induced transparency (EIT)-like effects show significant potential for biosensing due to their narrow transparent peak. This study aims to fabricate terahertz metamaterials based on EIT effect for non-destructive, trace-level detection of BSA.

Methods

We demonstrate a multiband EIT-like metasurface that merges C-, toroidal, and D-shaped resonators to generate two transparency windows at 0.973 and 1.118 THz via strong bright-bright near-field coupling between adjacent resonators. Finite-element modelling was used to optimise the bright-bright near-fiel
