To simulate life's emergent functions, mining the multiple sensing capabilities of nanosystems, and digitizing networks of transduction signals and molecular interactions, is an ongoing endeavor. Here, multifunctional antimonene‐silver nanocomposites (AM‐Ag NCs) are synthesized facilely and fused for molecular sensing and digitization applications (including ultra‐multi‐mode and multi‐analyte sensing, parallel and batch logic computing, long‐text information protection). By mixing surfactant, AM, Ag+ and Sodium borohydride (NaBH4) at room temperature for 5 min, the resulting NCs are comprised of Ag nanoparticles scattered within AM nanosheets and protected by the surfactant. Interestingly, AM‐Ag NCs exhibit ultra‐multi‐mode sensing ability for multiplex metal ions (Hg2+, Fe3+, or Al3+), which significantly improved selectivity (≈2 times) and sensitivity (≈400 times) when analyzing the combined channels. Moreover, multiple sensing capabilities of AM‐Ag NCs enable diverse batch and parallel molecular logic computations (including advanced cascaded logic circuits). Ultra‐multi‐mode selective patterns of AM‐Ag NCs to 18 kinds of metal ions can be converted into a series of binary strings by setting the thresholds, and realized high‐density, long‐text information protection for the first time. This study provides new ideas and paradigms for the preparation and multi‐purpose application of 2D nanocomposites, but also offers new directions for the fusion of molecular sensing and informatization.

用于超多模式和多分析物传感、并行和批量逻辑计算、长文本信息保护的多功能锑烯-银纳米复合材料


为了模拟生命的新兴功能，挖掘纳米系统的多重传感能力，以及将转导信号和分子相互作用的网络数字化，是一项持续的努力。在这里，多功能锑烯-银纳米复合材料（AM-Ag NC）被轻松合成并融合，用于分子传感和数字化应用（包括超多模式和多分析物传感、并行和批处理逻辑计算、长文本信息保护）。通过在室温下将表面活性剂、AM、Ag+和硼氢化钠 (NaBH4) 混合 5 分钟，所得的 NC 由分散在 AM 纳米片内的 Ag 纳米颗粒组成，并受到表面活性剂的保护。有趣的是，AM-Ag NCs 对多重金属离子（Hg2+、Fe3+ 或 Al3+）表现出超多模式传感能力，在分析组合通道时显着提高了选择性（约 2 倍）和灵敏度（约 400 倍）。此外，AM-Ag NC 的多种传感功能可实现多种批量和并行分子逻辑计算（包括先进的级联逻辑电路）。 AM-Ag NCs对18种金属离子的超多模式选择性模式可以通过设置阈值将其转换为一系列二进制串，并首次实现了高密度、长文本信息保护。该研究为二维纳米复合材料的制备和多用途应用提供了新的思路和范式，也为分子传感与信息化的融合提供了新的方向。
