Abstract The concept of a quasi‐bound state in continuum (QBIC) has garnered significant attention various fields such as sensing, communication, and optical switching. Within metasurfaces, QBICs offer reliable platform that enables sensing capabilities through potent interactions between local electric matter. Herein, novel terahertz (THz) biosensor based on the integration QBIC with graphene is reported, which multidimensional detection. proposed distinctive because its ability to discern concentrations ethanol N‐methylpyrrolidone wide range from 100% 0%, by monitoring changes resonance intensity maximum wavelet coefficient. This approach demonstrates an excellent linear fit, ensures robust quantitative analysis. remarkable sensitivity our it detect minute low‐concentration solutions, lowest detection concentration value (LDCV) 0.21 pg mL −1 . 2D coefficient cards are effectively constructed continuous transforms, presents more accurate for determining solution. Ultimately, offers host advantages, including heightened reusability. pioneering establishes new avenue liquid‐based biosensing.

Graphene-based terahertz (THz) metamaterials (MMs) are at the forefront of high-sensitivity sensing, with applications spanning biochemical to environmental fields. This review examines recent advances in graphene MMs-based THz sensors, covering foundational theories and innovative designs, from complex patterns graphene-dielectric graphene-metal hybrids. We explore ultra-trace detection enabled by $$\pi$$ - stacking mechanisms, expanding capabilities beyond conventional refractive index-based methods. Despite significant theoretical progress, practical challenges remain due material constraints; solutions such as multilayer structures hybrid low-mobility designs discussed enhance experimental feasibility. provides a comprehensive perspective on evolving impact MMs, positioning them transformative tools multidisciplinary sensing.
