Abstract

Skin cancer is the most common type of cancer worldwide, and early detection is critical to enhancing the success of treatments. The conventional methods of detection, although efficient, tend to be invasive and can be painful. The focus of this paper is to describe the development of a photonic crystal fiber (PCF)-based biosensor as an accurate, sensitive, and non-invasive device for the detection of early-stage melanoma. The sensor proposed here employs a 2D rectangular lattice structure with silicon rods in an air background, maximizing light manipulation to sense changes in the refractive index between normal and cancerous skin tissues. The optical response of the sensor is modeled using OptiFDTD software to analyze its performance, such as wavelength, sensitivity, and interaction with skin tissues. Simulation results reveal a remarkable distinction in the transmission spectra between melanoma and normal cells, confirming the sensor’s capability for real-time, precise cancer detection. This research emphasizes the potential of PCF-based biosensors in transforming early cancer diagnosis, leading to more efficient treatments and better patient outcomes.
