It is a great challenge to effectively eradicate biofilm and cure biofilm-infected diseases because dense extracellular polymeric substance matrix prevents routine antibacterial agents from penetrating into biofilm. H2 is an emerging energy-regulating molecule possessing both high biosafety and high tissue permeability. In this work, we propose a concept of sonocatalytic hydrogen/hole-combined ‘inside/outside-cooperation’ anti-biofilm for promoting bacteria-infected diabetic wound healing based on piezoelectric two-dimensional nanomaterials. Proof-of-concept experiments using C3N4 nanosheets as a representative piezoelectric catalyst with wide band gap and high biosafety have verified that sonocatalytically generated H2 and holes rapidly penetrate into biofilm to inhibit bacterial energy metabolism and oxidatively deprive polysaccharides/NADH in biofilm to destroy the bacterial membrane/electron transport chain, respectively, inside/outside-cooperatively eradicating biofilm. A bacteria-infected diabetic wound model is used to confirm the excellent in vivo anti-bacterial performance of sonocatalytic hydrogen/hole-combined therapy, remarkably improving bacteria-infected diabetic wound healing. The proposed strategy of sonocatalytic hole/hydrogen-combined ‘inside/outside-cooperation’ will break a highway for treatment of deep-seated biofilm infection.

Wet‐chemical synthesis refers to the bottom‐up chemical synthesis in solution, which is among the most popular synthetic approaches towards functional two‐dimensional (2D) materials. It offers several advantages including cost‐effectiveness, high yields, and precious control over the production process. As an emerging family of 2D materials, elemental 2D materials (Xenes) have shown great potential in various applications such as electronics, catalysts, biochemistry, and sensing technologies due to their exceptional/exotic properties such as large surface area, tunable band gap, and high carrier mobility. In this review, we provide a comprehensive overview of the current state‐of‐the‐art in wet‐chemical synthesis of Xenes including tellurene, bismuthene, antimonene, phosphorene, and arsenene. The current solvent compositions and process parameters utilized in wet‐chemical synthesis and their effects on the thickness and stability of the resulting Xenes are also presented. Key factors considered involves ligands, precursors, surfactants, reaction time, and temperature. Finally, we highlight recent advances and existing challenges in the current application of wet‐chemical synthesis for Xenes production and provide perspectives on future improvement.

With the increasing demands for novel flexible organic electronic devices, conductive polymers are now becoming the rising star for reaching such targets, which has witnessed significant breakthroughs in the fields of thermoelectric devices, solar cells, sensors, and hydrogels during the past decade due to their outstanding conductivity, solution‐processing ability, as well as tailorability. However, the commercialization of those devices still lags markedly behind the corresponding research advances, arising from the not high enough performance and limited manufacturing techniques. The conductivity and micro/nano‐structure of conductive polymer films are two critical factors for achieving high‐performance microdevices. In this review, the state‐of‐the‐art technologies for developing organic devices by using conductive polymers are comprehensively summarized, which will begin with a description of the commonly used synthesis methods and mechanisms for conductive polymers. Next, the current techniques for the fabrication of conductive polymer films will be proffered and discussed. Subsequently, approaches for tailoring the nanostructures and microstructures of conductive polymer films are summarized and discussed. Then, the applications of micro/nano‐fabricated conductive films‐based devices in various fields are given and the role of the micro/nano‐structures on the device performances is highlighted. Finally, the perspectives on future directions in this exciting field are presented.
