The induced structural transformation provides an efficient way to precisely modulate the fine structures and the corresponding performance of gold nanoclusters, thus constituting one of the important research topics in cluster chemistry. However, the driving forces and mechanisms of these processes are still ambiguous in many cases, limiting further applications. In this work, based on the unique coordination mode of the pincer ligand-stabilized gold nanocluster Au(PNP), we revealed the site-recognition mechanism for induced transformations of gold nanoclusters.

- The study focuses on understanding chirality at the nanoscale using atomically precise metal nanoclusters, which serve as a bridge between molecular and macroscopic chirality.
- Researchers developed a method to create enantiopure metal nanoclusters by converting achiral Au(SCH) nanoclusters into chiral Au(L)(SCH) nanoclusters via a chiral inducer, phosphoramidite (L).
- The resulting two enantiomers showcased unique crystal structures, with their chirality stemming from both the chiral molecules introduced and the arrangement of the nanocluster's surface motifs, and their chiroptical properties exhibited a specific negative nonlinear relationship.
Atomically precise metal nanoclusters have received tremendous attention due to their unique structures and properties. Although synthetic approaches to this kind of nanomaterial have been well developed, methods toward precision functionalization of the as-synthesized metal nanoclusters are extremely limited, hindering their interfacial modification and related performance improvement. Herein, an amidation strategy has been developed for the precision functionalization of the Au nanocluster based on preorganized nitrogen sites.

Construction of open sites on the surface of the metal nanocluster is a long-pursued but challenging goal. Herein, we realized the construction of "open organic sites" in a metal nanocluster for the first time.

Objective: To develop a rapid and specific method for hepatitis C virus ( HCV) genotyping using reverse dot blot hybridization technique and investigate the distribution of HCV genotypes and subtypes in Guangdong.
Methods: The primers and the probes targeting the 5'untranslated region (5'UTR) and core region of HCV genotypes 1b, 2a, 3a, 3b and 6a were designed, and the RT-PCR reverse dot blot hybridization (PCR-RDH) method for HCV genotyping was established. A total of 115 patients with hepatitis C were genotyped using this method, and 38 of them were also genotyped by sequencing and phylogenetic analysis to evaluate the accuracy and specificity of the method.
Background: There were some papers published in the Jonrnal of Science, December 2000 suggesting that one or more important susceptibility genes for late onset Alzheimer's disease (LOAD) were located on the long arm of chromosome 10. Linkage analysis showed maximum lod score close to D10S1225 loci, which indicated the loci might contribute to the etiology of Alzheimer's disease (AD).
Methods: Fifty-nine LOAD patients and 107 controls were recruited.
