Ultrasensitive Terahertz Biodetection
In article number 2301165, Chao Chang, Xiaohui Du, and co‐workers demonstrate a chip‐based portable ultra‐sensitive THz metasensor by exploring quasi‐bound states in the continuum and report its capability for sensing low‐concentration analytes. The designed metasensor is made of the designed split‐ring resonator metasurface combining functionalized gold nanoparticles...
Advanced sensing devices, highly sensitive, and reliable in detecting ultralow concentrations of circulating biomarkers, are extremely desirable and hold great promise for early diagnostics and real‐time progression monitoring of diseases. Nowadays, the most commonly used clinical methods for diagnosing biomarkers suffer from complicated procedures and being time consumption. Here, a chip‐based portable...
