Summary: In this study, a novel TPP biosensor was proposed by using a one-dimensional topological photonic crystal (1D TPhC) as the distributed Bragg reflector (DBR) at a working wavelength of 633 nm. The strong field confinement of 1D TPhC improved the light absorption of TPP and enhanced the sensitivity of the biosensor. The proposed biosensor demonstrated high sensing performance in both TE and TM polarization modes.

Summary: We investigate the impact of topological inhomogeneity on the response of thin metallic conductometric sensors to external stimuli. The percolation model is extended to consider multiple independent scattering mechanisms contributing to resistivity, with each scattering term predicted to increase and diverge at the percolation threshold. Experimental tests using thin films of hydrogenated palladium and CoPd alloys support the model, showing a linear growth in hydrogen scattering resistivity in the fractal topology range. This enhancement in resistivity response can be beneficial for detecting small changes in bulk material response.

Summary: Photonic crystals are widely used in biosensing applications. Researchers are seeking more economical protocols for preparing photonic crystals due to the complicated procedure for their self-assembly. In situ monitoring of glucose with photonic crystals is currently a main technique for controlling diabetes. In this study, a one-dimensional photonic crystal gel sensor was successfully prepared using a commercially available CD-R or DVD-R disc as a nanomold. The sensor showed good response ability to glucose and could detect glucose in urine with a limit of detection of 0.1 mM. The use of the existing optical disc microstructure as a template in the preparation of the 1-D photonic crystal sensor offers the advantages of simple preparation, short production cycle, and low cost. It also has great potential for application in point-of-care sensors.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
