Abstract
A terahertz (THz) sensor is presented based on a metasurface integrated with Au nanoparticles (AuNPs). It was used to improve the sensitivity of the detection of whey protein and to enhance the sensing index of group delay. This demonstrates that AuNPs can improve the sensing performance of the biosensor. The internal mechanism can be explained by the modified perturbation theory and the coupled harmonic oscillator model. This study provides a means of enhancing the sensitivity of the THz biosensor.
