Smart Bioinspired Material‐Based Actuators: Current Challenges and Prospects

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
This work gathers, in a review style, an extensive and comprehensive literature overview on the development of autonomous actuators based on synthetic materials, bringing together valuable knowledge from several studies. Furthermore, the article identifies the fundamental principles of actuation mechanisms and defines key parameters to address the size

Uncovering Aggregation‐Induced Emission in Carbon Dots for Color‐Changing Hydrogels and Information Encryption

Angewandte Chemie, EarlyView.
Red‐emissive carbon dots (R‐CDs) exhibiting aggregation‐induced emission (AIE) and aggregation‐caused quenching (ACQ) effects are synthesized from citric acid and urea. They display weak blue fluorescence in water but strong red emission in DMF due to aggregation.

Nitro Reduction‐Based RNA Control and Ultrafast Release

Angewandte Chemie, EarlyView.
A chemical RNA caging–uncaging strategy based on nitro reduction is described. Nitroaryl groups introduced via acylation temporarily block the functions of diverse RNAs in vitro and in living cells. Treatment with a diboronic acid–bipyridine mixture rapidly reduces the nitro groups, releasing RNAs and restoring their activity.

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation

Angewandte Chemie International Edition, EarlyView.
Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.
