Summary: The theoretical investigation of a one-dimensional photonic crystal based sensor for sensing blood plasma and cancer cells showed that the sensitivity can be increased by increasing sample thickness and adding additional layers of SiO2, while maintaining the same sensitivity value. The proposed sensor structure is compact, easy to fabricate, and cost-effective, with sensitivities of over 73 nm/RIU for cancer cells and 72 nm/RIU for hemoglobin in blood plasma.

Summary: We have developed a novel molecularly imprinted two-dimensional photonic crystal hydrogels (LVFXMIPCH) sensor for the visual monitoring of levofloxacin (LVFX). By measuring the diameter of the Debye diffraction ring, the response performance of the sensor was explored. The LVFX-MIPCH sensor showed high sensitivity (as low as 10^(-12) M), excellent specific recognition, and stable reusability.

Summary: One-dimensional photonic crystals (1DPhCs) combined with a thin Au layer are used to demonstrate Tamm resonances for potential sensor applications. Two different structures with TiO2/SiO2 bi-layers and a termination layer show Tamm resonances within different band gaps. The first structure exhibits wide band gaps over the visible and near-infrared spectral range, and the Tamm resonance depth and width depend on the thickness of the Au layer. The second structure, with band gaps in both spectral ranges, shows deep Tamm resonances for a 20 nm Au layer thickness.

Summary: A molecularly imprinted two-dimensional photonic crystal hydrogel sensor (SMZ-MIPCH) was developed for the sensitive and specific recognition of sulfamethoxazole (SMZ). The sensor showed a linear relationship between the variation of particle spacing and the logarithm of SMZ concentration, with a detection limit of 10(-16) mol L-1. The sensor displayed high sensitivity, specific recognition abilities for SMZ, and naked eye detection, making it suitable for SMZ detection in water samples.

Summary: Photonic crystal fibers (PCFs) have unique light-guiding properties and have been widely studied for biomedical applications. PCF-based fluorescence sensors offer highly sensitive detection of biomolecules at low sample volumes. This review discusses recent advancements in fluorescence detection using different PCF configurations and compares them with conventional fluorescence methods. Prospective applications of PCF-based fluorescence sensing and their potential use as optofluidic biopsy needles for clinically relevant biomarker detection are also discussed.

Summary: Structural color can be produced by nanoperiodic dielectric structures using soft materials, and stretchable chiral photonic elastomers (CPEs) can self-organize into a helical nanostructure, with the chiral nanostructural color controlled by stretching. This study presents stretchable CPEs with simultaneous multicolor control, including electrical control, and demonstrates various device applications such as multiarrayed color binning and chameleon-like photonic e-skin. The ability to control the separation of biomimetic multicolors in stretchable photonic systems improves the functionality of potential photonic applications.

Summary: In this work, a narrow-band filter based on a one-dimensional photonic crystal heterostructure with an angle-adjustable single channel was designed. The filter design relies on a quarter-wave reflector with a mirror defect layer to achieve resonant peaks at specific wavelengths for different incident angles. This structure offers narrow passbands and sharp angular pass breadth, making it suitable for applications in angular tunable, single-channel narrow-band filters.

Summary: The transfer of graphene can introduce defects and contamination, increasing costs, therefore, growing graphene directly on silicon wafers is highly desirable. In this study, we demonstrate the direct chemical vapor deposition (CVD) growth of monolayer graphene on a SiO2 layer on a silicon wafer using a Pt thin film as a catalyst. By adjusting the CVD process, we were able to achieve transfer-free growth of monolayer graphene on 4-inch oxidized silicon wafers, a result that is not easily obtained using other methods. Selective growth of graphene on SiO2 was achieved by adding Ta structures.
