Terahertz Metasensor with Pseudo Parity Time Symmetry for Oral Cancer Diagnostics / Z.A.Zaky, A.Hennache, V.D.Zhaketov. – Text : electronic // Scientific Reports. – 2025. – Vol. 15. – P. 29424. – URL: https://doi.org/10.1038/s41598-025-14176-9. – Bibliogr.: 50.
This study presents the design and theoretical analysis of a pseudo parity-time symmetric photonic crystal biosensor for early oral cancer detection. Using the transfer matrix method, we numerically investigated the resonant transmission properties of a 1D photonic crystal structure with a central defect layer (D = 50 μm) containing healthy and cancer oral cells. The proposed (SiO&sub(2) ∗ Si)N (oral cells) (SiO&sub(2) ∗ Si)N ∗ substrate configuration exhibits exceptional sensitivity, quantified by two key metrics: a spectral sensitivity of 118 GHz/RIU and an extraordinary transmittance sensitivity of 1.9 × 10*8 %/RIU. These results demonstrate significant improvements over conventional photonic biosensors, enabled by the PT-symmetric design’s ability to operate near an exceptional point. The optimized structure achieves ultra-sharp resonances ( 9.1 × 10*-*5 THz FWHM) with remarkable field enhancement, making it particularly suitable for detecting minute refractive index changes associated with malignant transformations. Our findings establish a foundation for developing high-performance, label-free diagnostic tools for early-stage oral cancer detection.
