Key Points

  • The aim is to develop a quadband THz metasurface biosensor for improved sensitivity in biomedical sensing applications.
  • Proposed a compact quadband THz metasurface design
  • Evaluated absorption and sensitivity through multi-resonant structures
  • Assessed performance in terms of angular stability and discrimination against healthy and affected samples.
  • Demonstrated high absorption rates across multiple resonances
  • Achieved enhanced sensitivity leading to reliable differentiation of healthy, malignant, and infected samples
  • Showed angular stability in performance across various orientations.

Abstract

A compact quadband THz metasurface biosensor is proposed for biomedical sensing. Its multi-resonant design provides high absorption, enhanced sensitivity, angular stability, and effective discrimination of healthy, malignant, and infected samples.
