Metamaterials (MMs) enable the manipulation of terahertz (THz) waves, which are vital for numerous applications due to their unique spectral fingerprints, non-ionizing nature, sensitivity weak resonances, and strong penetration through non-polar materials. However, detecting minor disturbances subtle features in biological chemical sensing is challenging when object’s scale smaller than THz wavelength. This limits development bio-chemical detection technology. MMs offer a solution, with recent research combining these materials new structures mechanisms enhance sensitivity. article reviews progress sensing, focusing on key performance parameters like spoof surface plasmon polaritons (SSPPs), bound states continuum (BIC), electromagnetically induced transparency (EIT). It explores future directions biomedical diagnostics, non-destructive testing, security, environmental highlighting transformative impact

Terahertz spectroscopy has drawn great interest for the detection and characterization of biological matter, but its limited sensitivity to biomolecules with weak changes in dielectric properties varying concentration hinders potential bio-sensing applications. Here, a novel terahertz sensor was developed enhancing ability detect based on two electromagnetically induced transparency (EIT) metamaterials coupled gold nanoparticles (AuNPs) integrated biomolecules. The electrostatic interaction between AuNPs positively charged generates localized field enhancement at biomolecule–metamaterial interface, resulting threefold increase histidine that exhibit property concentration. As contrast, glucose shows weaker effect due electrostatically neutral nature. Experimental studies reveal by evaluating modulation depth (MD) (ME) factors transmission peak presence AuNPs, we achieve enhance intuitive discrimination these Additionally, two-EIT metamaterial 1 × 2 pixel array enables multiparameter imaging, visualizing spatial distribution Our results not only significantly improve response domain, also provide new idea developing high-sensitivity functionalized biosensors advancing multi-biomolecular analysis imaging techniques.
