Aspect Ratio‐Controlled Chiral Nanostructures for Dual‐Mode Breast Cancer Theranostics
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Chiral CdSe/CdS quantum dots (QDs) have emerged as promising platforms for precise cancer diagnosis and therapy due to their unique optical properties and biological interactions. In this study, we systematically investigated the role of aspect ratio (AR) modulation in ultrathin‐shelled chiral CdSe/CdS dot‐in‐rods (DRs) on their performance in

四川大学学报. 自然科学版, 2009 研究了曲酸对胰蛋白酶活性的影响,以及曲酸处理的胰蛋白酶的紫外光谱、荧光淬灭光谱、同步荧光光谱和三维荧光光谱.结果显示曲酸对胰蛋白酶具有激活作用;二者相互作用后,曲酸可以使胰蛋白酶的紫外吸收强度增强,但却使得蛋白内源荧光强度下降.Stern-Volmer作图显示了曲酸对胰蛋白酶的荧光淬灭为静态淬灭作用,求出二者的结合常数K为5.30×10～7L/mol,结合位点n为1.50;用同步荧光光谱和三维荧光光谱探讨了曲酸对胰蛋白酶构象的影响.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Multimodal luminescent materials are crucial for advanced information encryption, real‐time dosimetry, and high‐resolution bioimaging, yet integrating orthogonal stimulus‐responsiveness into a single‐component system is challenging. Herein, we report a Pr3+‐doped Ca3Ga2Ge3O12 (CGGO: Pr3+) garnet phosphor that exhibits orthogonally addressable ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Perovskite quantum dots (QDs) have been considered as promising emitters for lighting and display applications, but they suffer from poor thermal stability under operation. Herein, we introduce sub‐micrometer Ag particles to simultaneously enhance the luminescence intensity and thermal stability of perovskite QDs.
