Inspired by information exchange and logic functions of life based on molecular recognition and interaction networks, ongoing efforts are directed toward development of molecular or nanosystems for multiplexed chem/biosensing and advanced information processing. However, because of their preparation shortcomings, poor functionality, and limited paradigms, it is still a big challenge to develop advanced nanomaterials-based systems and comprehensively realize neuron-like functions from multimode sensing to molecular information processing and safety. Herein, using fish scales derived carbon nanoparticles (FSCN) as a reducing agent and stabilizer, a simple one-step synthesis method of multifunctional silver–carbon nanocomposites (AgNPs–FSCN) is developed. The prepared AgNPs–FSCN own wide antibacterial and multisignal response abilities in five channels (including color, Tyndall, absorption and fluorescence intensities, and absorption wavelength) for quantitative colorimetric and fluorescence sensing of H₂O₂, ascorbic acid, and dopamine. Benefiting from its multicoding stimuli-responsive ability, molecular concealment, and programmability, AgNPs–FSCN can be abstracted as nanoneurons for implementing batch and parallel molecular logic computing, steganography, and cryptography. This research will promote the preparation of advanced multifunctional nanocomposites and the development of their multipurpose applications, including the multireadout-guided multianalyte intelligent sensing and sophisticated molecular computing, communication, and security.

多功能碳纳米复合材料作为纳米神经元，从多模式和多分析物传感到分子逻辑计算、隐写术和密码术

受基于分子识别和相互作用网络的生命信息交换和逻辑功能的启发，正在进行的努力旨在开发用于多重化学/生物传感和高级信息处理的分子或纳米系统。然而，由于它们的制备缺陷、功能差和范式有限，开发基于纳米材料的先进系统并全面实现从多模传感到分子信息处理和安全的类神经元功能仍然是一个很大的挑战。在这里，使用鱼鳞衍生的碳纳米粒子（FSCN）作为还原剂和稳定剂，开发了一种简单的多功能银碳纳米复合材料（AgNPs-FSCN）的一步合成方法。₂ O ₂、抗坏血酸和多巴胺。受益于其多编码刺激响应能力、分子隐藏性和可编程性，AgNPs-FSCN 可以被抽象为纳米神经元，用于实现批量和并行分子逻辑计算、隐写术和密码学。这项研究将促进先进多功能纳米复合材料的制备及其多用途应用的发展，包括多读数引导的多分析物智能传感和复杂的分子计算、通信和安全。
