    “In the field of micro-nano lasers, a new study introduces ethyl acetate as a green antisolvent to create high-quality quasi-2D perovskite films. This innovation enhances crystallinity, inhibits low n-phases, and extends gain lifetime, leading to a significant reduction in ASE threshold and high net modal gain. The optimized film enables a VCSEL with single-mode lasing and a high quality factor, advancing scalable photonic integration.”

    摘要：Quasi-two-dimensional （quasi-2d） perovskites are promising gain media for micro-nano lasers， yet their uncontrolled crystallization and abundant low-n phases often hinder optical gain and device performance. In this work， we introduce ethyl acetate （EA） as a green antisolvent to fabricate high-quality quasi-2D PEA0.4MAPbBr3 films. The EA-treated films exhibit superior morphology， enhanced crystallinity， and notably inhibited low n-phases. These improvements yield a prolonged photoluminescence lifetime of 26.3 ns and a substantially extended gain lifetime of 129 ps. Consequently， the optimized film exhibits a markedly reduced amplified spontaneous emission （ASE） threshold of 5.6 μJ·cm-2 and a high net modal gain of 935 cm-1. Leveraging these enhanced gain properties， we successfully demonstrate a vertical-cavity surface-emitting laser （VCSEL） based on a dielectric Bragg reflector microcavity， which delivers single-mode lasing at 528.3 nm and a high quality factor of ~5 886. This work presents a green-solvent-engineering strategy for high-performance perovskite lasers， advancing their prospects for scalable photonic integration.

    摘要：Lanthanide-doped nanoparticles （LnNPs） have long been regarded as electrically inactive due to their insulating hosts. A recent strategy enables electrical activation by introducing exciton-forming organic ligands as energy mediators， achieving efficient and color-tunable visible and near-infrared LnLEDs. This breakthrough overcomes the insulation bottleneck and opens new opportunities for high-color-purity displays and infrared photonic devices.

    摘要：Cystatin C（Cys C） is an important biomarker for evaluating and monitoring renal function and is widely used for early screening of kidney disease. Fluorescent lateral flow immunoassay is a convenient approach for rapid and quantitative Cys C testing， yet its analytical performance is often constrained by the brightness and stability of conventional signal labels. Here， we report a water-stable perovskite quantum dot（PQD）-based fluorescent bioprobe for use in Cys C LFIA. Mesoporous silica nanoparticles（MSNs） were employed as nanocarriers， enabling in situ formation of CsPbBr3 quantum dots within the mesopores while a SiO2 sealing layer was simultaneously constructed. The resulting CsPbBr3@MSNs@SiO2 probes exhibited high photoluminescence quantum yield（PLQY≈93%） and excellent water stability（>120 h）， providing robust signal output for LFIA readout. Based on this bioprobe， a fluorescent LFIA strip was fabricated for quantitative Cys C detection， demonstrating good specificity and a clear concentration-dependent response. This work offers a bright and water-stable labeling strategy for point-of-care testing of renal function-related biomarkers and expands the utility of metal halide PQDs in bioanalysis and LFIA-based diagnostics.

    摘要：Aptamer-based sandwich immunosensors are an emerging analytical platform that combines the high specificity recognition of aptamers with the high sensitivity of immunoassays. Due to their advantages of excellent selectivity and low detection limits， these biosensors hold great potential for use in bioanalytical applications. This review outlines the key strategies underlying such biosensors， including aptamer selection， sandwich structure construction， and nanomaterial-enhanced signal amplification， and surveys recent advances in their bioanalytical application for the detection of small molecules， proteins， and pathogenic microorganisms. Current challenges and promising future directions for the field are also discussed.
