Despite mounting evidence suggesting that fibrosis is reversible, effective treatments for fibrotic diseases are lacking. Accumulating evidence has elucidated that ribonucleic acid (RNA) modifications have emerged as novel mechanisms regulating gene expression. N6-methyladenosine (m6A) modification is a well-known prevalent RNA posttranscriptional modification that participates in essential biological processes such as RNA splicing, translation, and degradation. It is tightly implicated in a wide range of cellular processes and various human diseases, particularly in organ fibrosis. The m6A modification is a dynamic and reversible process regulated by methylases, commonly known as \"writers,\" and demethylases referred to as \"erasers,\" while m6A modifications are recognized by \"readers.\" Accumulating evidence suggests that m6A modification on RNAs is tightly associated with fibrotic diseases of visceral organs including the lungs, heart, liver, and kidney.

Recently, hydrogels have gained prominence for use in HMI electrodes because these soft, hydrated materials are similar in nature to human tissues and can be tuned through the incorporation of nanofillers. This review examines the functional requirements of HMI electrodes and highlights recent progress in the development of polyphenol-mediated multifunctional hydrogel-based HMI electrodes for bioelectronics. Furthermore, aspects such as mussel-inspired and polyphenol-mediated adhesion, underlying mechanisms, tissue-matching mechanical properties, electrochemical performance, biocompatibility, biofouling resistance, stability under physiological conditions, anti-inflammatory, and antioxidant properties are discussed.

Herein, the nucleation-controlled doping process facilitated by magic-sized cluster intermediates is elucidated. This approach enables the synthesis of 2D ZnSe quantum nanoribbons with two distinct doping sites.
