Development of a miniaturized chemiluminescence lateral flow immunoassay platform with ultra-high sensitivity and ultra-low background for cardiac troponin I.

Background: Lateral flow immunoassays (LFA) are widely used for disease diagnostics due to their simplicity and portability. However, they often suffer from limited sensitivity and accuracy, making them unsuitable for quantitative detection. Additionally, the adsorption and non-specific interactions between label particles and the nitrocellulose membrane may lead to increased background noise, which compromises the repeatability of the device.

Large-Scale Perovskite Single Crystal Growth and Surface Patterning Technologies.

In the past decade, metal halide perovskite polycrystalline films have witnessed significant advancements in the field of high-performance optoelectronic devices, including photodetectors, solar cells, light-emitting diodes, and lasers. Perovskite films with periodic micro/nanoarrays have garnered substantial attention due to their capability not only to improve the efficiency of individual devices but also to hold great promise for future commercialization. Surpassing their polycrystalline counterparts, perovskite single crystals typically exhibit longer carrier diffusion lengths, extended carrier lifetimes, and enhanced carrier mobility due to the absence of grain boundaries and reduced defects, positioning them as promising candidates for both fundamental studies and advanced optoelectronic devices.

Metal-organic framework (MOF)-incorporated polymeric electrolyte realizing fast lithium-ion transportation with high Li transference number for solid-state batteries.

Composite polymer electrolytes (CPEs) show significant advantages in developing solid-state batteries due to their high flexibility and easy processability. In CPEs, solid fillers play a considerable effect on electrochemical performances. Recently, metal-organic frameworks (MOFs) are emerging as new solid fillers and show great promise to regulate ion migration.

Structural Regulation of Pd-Based Nanoalloys for Advanced Electrocatalysis.

Palladium (Pd)-based materials have attracted increasing attentions as a kind of novel candidate catalysts for many electrocatalytic reactions to replace classic platinum (Pt) catalysts, especially in the fuel cell-related electrocatalysis. However, the requirement of high activity and stability toward further practical applications makes the development of Pd-based catalysts cease to advance. Combining alloying and structure-controlled strategies has well addressed this challenge by optimizing the adsorption/desorption behaviors toward reaction intermediates.
