Designing a high-sensitivity dual-band nano-biosensor based on petahertz MTMs to provide a perfect absorber for early-stage non-melanoma skin cancer diagnostic
Abstrakt
The purpose of this study is development of a novel high-performance low-Petahertz (PHz) biosensor for non-melanoma skin cancer (NMSC) diagnosis. The presented device is designed to work within a microwave imaging regime, which is a promising alternative to conventional diagnostic methods such as visual examination, dermoscopy, and biopsy. The suggested biosensor incorporates a dual-band perfect absorber (operating bands at 0.909 PHz and 1.215 PHz) constructed using aluminum layers separated by a dielectric material. Numerical studies confirm its suitability for NMSC diagnosis, enabling discrimination between healthy and cancerous skin tissues and precise visualization of affected areas. Compared to existing THz devices, the proposed biosensor offers improved sensitivity, a smaller size, and enhanced resolution, attributed partially to the transition to the petahertz band. Moreover, our research highlights the potential of PHz spectroscopy for biomarker detection, advancing non-invasive microwave imaging techniques for NMSC and other skin cancers. The proposed biosensor boasts higher sensitivity, figure of merit (FOM), and quality factor (Q-factor), while its insensitivity to polarization angle ensures superior signal-to-noise ratio and high-resolution imaging, instilling confidence in specialists.
