Abstract
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 conjugated with the specific antibody.
