Summary: The development of transient electronic devices is crucial for protecting sensitive information stored in electronic memory devices. A flexible electronic device with a highly water-soluble active material has been successfully fabricated, showing rewritable resistive random access memory effect and history-dependent memristive switching performance. This device emulates the learning and memorizing functions of biological systems and can be rapidly destroyed by adding water.

Summary: This study comprehensively investigates the properties of polarons and bi-polarons in CPEs, including their stability, structural deformation, electronic structure, and optical absorption. The research reveals that these properties depend on the electrostatic interaction between the polarons and ionic functionalities, as well as the combinations of donor and acceptor units in the CPEs backbones. Additionally, the study sheds light on the electrochemical stability of CPEs and discusses strategies to improve it.

Summary: The abnormal concentration of microRNAs can be used as potential biomarkers for various diseases, and electrochemical methods, especially those involving hybridization with single-stranded DNA or peptide-nucleic acid, show promise in their detection. Recent studies have explored the use of nanomaterials and catalyzed reactions to enhance the performance of these sensors. This study focused on the selection of a receptor layer composition for the detection of miRNA 141, using atomic force microscopy, surface plasmon resonance, and quartz-crystal microbalance techniques to analyze the formation of the receptor layer and the interaction between the probes and miRNA. Impedance spectroscopy showed that the use of unlabelled ssDNA as the receptor layer provided a detection limit of 0.1 pM, suggesting that this biosensor is a simple and effective alternative.
