Technical Background Diselenide-containing polymers have attracted considerable attention in recent years for their rapid responsiveness to external stimuli such as light and reducing environments, with potential applications in artificial enzymes, controlled drug release, and self-healing materials. Conventional synthetic routes to diselenide-containing polymers typically involve complex multi-step reactions and require highly...

Base-modified nucleoside analogs have been widely studied in the research and development of antiviral and antitumor drugs, among which the most representative is pseudouridine. Pseudouridine is the most abundant modified nucleoside in RNA and is also known as the "fifth nucleoside" of RNA. A large number of studies have shown...

Ordered mesoporous materials have shown tremendous potential in drug delivery, catalysis, energy storage, and environmental remediation, thanks to their tunable pore structures, high surface areas, and excellent stability. The research achievements of Prof. Dongyuan Zhao's team in this field have now been translated into a series of standardized products to...

What Are YL578 YueLu Dyes? YL578 (YueLu dyes) is a class of asymmetric rhodamine fluorescent probes engineered for high brightness, high photostability, and a large Stokes shift in super-resolution and confocal microscopy. Developed by the Zhang Xiaobing–Yuan Lin research group at Hunan University and published in Nature Communications (2022, 13,...

Compared with conventional (n-i-p) structures, inverted (p-i-n) perovskite solar cells offer advantages such as simpler fabrication, weaker hysteresis, and greater suitability for flexible substrates and tandem devices. As a result, inverted perovskite solar cells have attracted widespread attention in recent years. Common hole transport materials used in inverted perovskite solar...

Cell viability assays are widely used in cell biology, drug discovery, toxicology, cancer research, and biomedical research to evaluate viable cell number, proliferation, and cytotoxic effects. Among colorimetric methods, tetrazolium-based assays remain some of the most widely used options. Common reagents include MTT, XTT, MTS, and WST-8. Although all four...
