Multifunctional Carbon Nanocomposites as Nanoneurons from Multimode and Multianalyte Sensing to Molecular Logic Computing, Steganography, and Cryptography

Carbon nanoparticles derived from biowastes via physically exfoliation method are employed as reducing agents and stabilizers for one-step and green synthesis of multifunctional silver –carbon nanocomposites, which own antibacterial ability and show wonderful applications in multiplexed sensing, molecular logic, and molecular crypto-steganography due to the stimuli-responsive nanoneuron behaviors producing five signal modes when inputting hydrogen peroxide, ascorbic acid, and do pamine. AbstractInspired 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 ...
