“…In 2023, Çelik et al similarly developed an SPR sensor using a synthetic receptor developed by a molecularly imprinted polymer approach, and tested benzyl penicillin against aqueous solutions and in milk. 87 By detecting benzylpenicillin in the concentration range of 1–100 ppb, the detection limit reached 0.021 ppb. In terms of molecular selectivity, it was 8.16 times higher than that for amoxicillin and 14.04 times higher than for ampicillin.…”

“…Surface plasmon resonance (SPR) is also a sensing mechanism, and sensors based on SPR through the interaction between the sensing element and the metasurfaces [ 60 , 61 ]. This mechanism is through the target biochemical molecule binding, molecules concentration changes and chemical changes lead to changes in the local refractive index gradient, which excites the excitation of the surface plasma, generating terahertz waves through the frequency shift of the resonance peak.…”

Based on the extraordinary electromagnetic properties of terahertz waves, such as broadband, low energy, high permeability, and biometric fingerprint spectra, terahertz sensors show great application prospects in the biochemical field. However, the sensitivity of terahertz sensing technology is increasingly required by modern sensing demands. With the development of terahertz technology and functional materials, graphene-based terahertz metasurface sensors with the advantages of high sensitivity, fingerprint identification, nondestructive and anti-interference are gradually gaining attention. In addition to providing ideas for terahertz biosensors, these devices have attracted in-depth research and development by scientists. An overview of graphene-based terahertz metasurfaces and their applications in the detection of biochemical molecules is presented. This includes sensor mechanism research, graphene metasurface index evaluation, protein and nucleic acid sensors, and other chemical molecule sensing. A comparative analysis of graphene, nanomaterials, silicon, and metals to develop material-integrated metasurfaces. Furthermore, a brief summary of the main performance results of this class of devices is presented, along with suggestions for improvements to the existing shortcoming.
