Summary: In this study, we developed a monitoring scheme for nucleic acid amplification process using UiO-66-NH2. The release of pyrophosphate ion (PPi) during amplification competitively coordinates with Zr, weakening the ligand-to-metal charge transfer and causing fluorescence recovery, thus indicating the progress of amplification.

Summary: This study proposed a powerful ligand engineering strategy to eliminate surface defects and aggregation of CsPbBr3nanocrystals (NCs), improving their colloidal stability and fluorescence. The as-synthesized NCs with amphiphilic polymer-modified ligands exhibited high photoluminescence intensity and stability. Furthermore, the NCs showed enhanced water, photostability and thermal stability. Additionally, a colorimetric sensor based on these NCs was successfully constructed for the detection of chloride ions in sweat, enabling rapid, visual and accurate detection.

Summary: Elaborate chemical synthesis methods allow the production of inorganic nanocrystals with uniform shape and size distributions. Ion exchange reactions for ionic nanocrystals have been extensively studied due to the large surface-to-volume ratio of the nanoparticles. The cation exchange reactions proceed much faster than anion exchange reactions due to the larger ionic radii of anions within the frameworks of nanocrystals.

Summary: Thick-shell colloidal quantum dots (QDs) with size/composition/shape-tunable properties are promising for solar technologies. However, the commonly used toxic metal elements and wide bandgap of the shell limit their performance. This study develops eco-friendly AgInSe2/AgInS2 core/shell QDs, which are optically active in the NIR region and suitable for solar energy conversion. By using a template-assisted cation exchange method, gradient AgInSeS shell layers are incorporated, resulting in improved charge transfer and higher current density in the photoelectrochemical cells.

Summary: This study presents an ATP-activated prodrug system for on-demand treatment of bacterial infections. The system utilizes zeolitic imidazolate framework-8 and polyacrylamide hydrogel microspheres to transport indole-3-acetic acid and horseradish peroxidase, preventing premature activation of the prodrug. The ATP-responsive characteristic of zeolitic imidazolate framework-8 allows the system to be activated by bacterial-secreted ATP, generating reactive oxygen species for broad-spectrum antimicrobial ability. The leaked intracellular ATP from dead bacteria further enhances the activation of the prodrug system. In vivo experiments show the applicability of the system for wound disinfection with minimal side effects.

Summary: Cation exchange (CE) is a promising post-synthesis strategy for colloidal nanocrystals, and the choice of cation precursor significantly affects the CE process and the final nanocrystals. In this study, two Zn-B Lewis acid-base adduct complexes were used as Zn precursors for CE with Ag2S quantum dots. The results showed that the steric hindrance and complexing capabilities of the precursor greatly influenced the CE kinetics and led to the formation of Zn-doped Ag2S and Ag2S@ZnS core-shell quantum dots. Theoretical simulation provided insights into the formation mechanisms of these nanocrystals.
