Summary: In this study, a novel highly stable opal photonic crystal (OPC) structure was designed to enhance up-conversion fluorescence through the OPC effect, and a sensitive novel coronavirus IgG up-conversion FRET-based sensor was successfully constructed. The water stability and mechanical stability of polymer OPC were addressed by a polymer spray combined with a flipped OPC film strategy. Based on this, a fluorescence resonant energy transfer (FRET) based novel coronavirus IgG antibody sensor was developed, which demonstrated a low detection limit and visual fast detection capability, providing an effective tool for early detection of the novel coronavirus.

Summary: Assays using fluorophores are common in life science research and diagnostics. However, weak emission intensity limits the detection limits, requiring a large number of labeled target molecules to improve signal-to-noise ratio. This study demonstrates that the synergistic coupling of plasmonic and photonic modes can significantly enhance the emission from fluorophores, resulting in a 52-fold improvement in signal intensity. The method is successfully applied to a sandwich immunoassay for human interleukin-6, achieving a detection limit three orders of magnitude lower than standard immunoassays.

Summary: In this study, Ba1-xZn1-yP2O7:xEu(2+/3+), yMg phosphors with rigid structures were prepared through solid-phase technology, and the gradual phase segregation from BaZnP2O7 to BaMgP2O7 was observed with increasing Mg2+ content. The phosphor exhibits tunable CIE coordinates and color emission, making it suitable for multicolor applications. Additionally, it shows potential for optical temperature measurement and anticounterfeiting purposes.

Summary: Gold nanoclusters (AuNCs) with bovine serum albumin (BSA) capping can be enhanced in fluorescence intensity by utilizing periodic, close-packed polystyrene colloidal photonic crystals (CPCs) to increase light-matter interactions. The fluorescence intensity of AuNCs was increased 14-fold when compared to the control sample. The BSA-AuNCs-CPC platform showed high sensitivity and selectivity in the fluorescence turn-off detection of creatinine at nanomolar level.

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: The utilization of a purely organic based room-temperature phosphorescent (RTPH) emitter as a sensitizer in yellow fluorescent organic light-emitting diodes (OLEDs) was studied. By co-doping the RTPH sensitizer and fluorescent dopant, efficient Forster energy transfer was achieved, resulting in an increase in the maximum external quantum efficiency of the yellow fluorescent OLEDs.
