Ultrasensitive, light-induced reversible multidimensional biosensing using THz metasurfaces hybridized with patterned graphene and perovskite

Haiyun Yao et al.

Summary: This article introduces a biosensor based on terahertz metasurfaces, consisting of a metasurface and a metal oxide semiconductor-like structure, which enables ultra-sensitive multidimensional detection. By varying the photoconductivity of the semiconductor-like structure, the biosensor can detect whey protein concentrations as low as 6.25 ng/mL, and significant variations in frequency, phase, and transmission amplitude were observed for different protein concentrations. Reversible biosensing in the terahertz region was also achieved by applying lasers with different wavelengths.

Three-stimulus control ultrasensitive Dirac point modulator using an electromagnetically induced transparency-like terahertz metasurface with graphene

Yonggang Zhang et al.

Summary: This letter presents a fabricated Dirac point modulator of a graphene-based terahertz electromagnetically induced transparency (EIT)-like metasurface. The modulation is achieved through three stimulus modes: optical pump, bias voltage, and optical pump-bias voltage combination. The position of the Dirac point can be evaluated approximately by analyzing the transmission spectrum fluctuation. The findings demonstrate a method for designing ultrasensitive terahertz modulation devices.
