This theoretical work focuses on the application of Tamm resonance-based biosensing using a one-dimensional photonic crystal for detecting skin vitiligo, a condition caused by the loss of pigment in the body. This biosensor utilizes the interaction of light with the photonic structure to identify the specific biomarkers associated with vitiligo. The proposed structure is composed of prism/Ag/skin-sample/(GaP/PS)/glass. The MATLAB simulations are used to obtain numerical results pertaining to the work by using the transfer matrix method (TMM). The analysis of transmission spectra of the proposed structure shows its minute sensing ability of detecting skin vitiligo. The proposed sensor possesses a higher sensitivity of 1200 nm/RIU which is higher than the sensitivities of the sensor reported earlier. Moreover, the suggested biosensor possesses an extremely high-quality factor value of 40,650 with an exceptionally small full-width-half-maximum value of 0.04 nm.

Gout, a common chronic disease, is characterized by the formation and deposition of monosodium urate (MSU) crystal deposition in articular and nonarticular structures. Osteoarthritis (OA), the most prevalent type of arthritis, is a progressive degenerative joint disease. Previous clinical studies have reported that gout frequently affects OA joints; however, the underlying mechanism remains unidentified.

The incorporation of polymeric insulators has led to notable achievements in the field of organic semiconductors. By altering the blending concentration, polymeric insulators exhibit extensive capabilities in regulating molecular configuration, film crystallinity, and mitigation of defect states. However, current research suggests that the improvement in such physical properties is primarily attributed to the enhancement of thin film morphology, an outcome that seems to be an inevitable consequence of incorporating insulators.

In laser safety eyewear, due to the lack of complete blocking of ultraviolet and infrared rays, we proposed a structure based on one-dimensional multilayer composed of several layers of silicon dioxide and zirconium dioxide materials alternately behind polycarbonate lens. It is find out that the acceptance angle range to the photonic crystal is 0 to 39°. This incident angle range corresponds to the band gap of the photonic crystal.
