AI Article Synopsis
- The first chiral molecular hybrids were created by linking polyoxometalate clusters with enantiopure 1,1'-binaphthyl units.
- Their structures were confirmed using techniques like (1)H NMR, FTIR, and ESI-MS.
- These hybrids display moderate chiroptical behavior in solutions, with Cotton effects observed up to 450 nm, suggesting a chiral influence from the binaphthyl core to the cluster-containing arms.
Article Abstract
The first chiral molecular hybrids based on covalently linked polyoxometalate clusters and enantiopure 1,1'-binaphthyl units have been prepared. Their structures have been confirmed by (1)H NMR, FTIR, and ESI-MS measurements. Such hybrids show moderate chiroptical behavior in solutions, and Cotton effects are observed up to 450 nm, indicating chiral extension from the binaphthyl core to the cluster-containing pi-conjugated arms.

The exchange of molecular information across kingdoms is crucial for the survival of both plants and their pathogens. Recent research has identified that plants transfer their small RNAs and microRNAs into fungal pathogens to suppress infection. However, whether and how plants send defense proteins into pathogens remains unknown.

MicroRNAs (miRNAs) serve as potential biomarkers for many diseases such as cancer, neurodegenerative diseases and cardiovascular conditions. The portable and accurate detection of miRNA is of great significance for the early diagnosis, treatment optimization and prognostic evaluation of diseases. Herein, a photothermal/visual dual-mode assay for let-7a is developed utilizing oxidized 3, 3', 5, 5' - tetramethylbenzidine (oxTMB) as signal reporter.

The challenge of increasing food production while maintaining environmental sustainability can be addressed by using biofertilizers such as Azospirillum, which can enhance plant growth and colonize more than 100 plant species. The success of this biotechnology depends on the amount of plant growth-promoting bacteria associated with the plant during crop development. However, monitoring bacterial population dynamics after inoculation requires time-consuming, laborious, and costly procedures.
