Binary materials combine the properties and advantages of their components, but their fabrication paradigm needs updating to fully exploit their characteristics and broaden their application. Here, multifunctional bimetallic gold-chromium nanocomposites (Au–Cr NCs) were synthesized facilely in a sequential-dependent manner, and applied from multi-channel sensing to molecular informatization (including advanced logic computing and tri-layer information protection). By sequentially mixing Cr 6+ , Au 3+ , and NaBH 4 (reducing agent), Au–Cr NCs with Au nanoparticles attached to Cr nanobelts can be prepared easily and quickly. The resulting Au–Cr NCs exhibited multi-signal sensing capability for hypochlorite, with significantly improved selectivity (about 5 times) and sensitivity (about 1650 times) when analyzing multiple signals. The synthesis process can be used to implement parallel molecular logic gates and customizable keypad lock operations. Moreover, by digitizing logical relationships and multimodal selective responses based on Au–Cr NCs, specific information (wise sayings and literary works sentence) can be encoded, encrypted and hidden to realize nano-cryptography and steganography. When combined with molecular keypad lock, a tri-layer information protection system can be constructed to enhance anti-cracking ability. This study promotes controllable preparation and multi-purpose applications of advanced multifunctional nanocomposites, but also opens up a new direction for nano-based sensing and digitization in multi-dimension.

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 H 2 O 2 , 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.

The sizes, shapes, and surface characteristics of nanomaterials determine their unique physical, chemical, and biological properties. Localized surface plasmon resonance (LSPR) is one of the unique optical properties of noble-metal nanoparticles. The synthesis of nanomaterials using biomolecules as templates offers an excellent strategy to control and regulate their features. Herein, for the first time, we demonstrate a green synthesis approach of silver nanoparticles (AgNPs) using nucleotide-based assemblies as templates. Moreover, we investigate the influence of different nucleotide-based assemblies and metal ions on the preparation of AgNPs, implying that AgNPs with different LSPR absorptions originating from their surrounding and size could be synthesized. The synthetic route is green, energy-effective, and feasible. On the basis of the unique LSPR-controlled property, the AgNP composites were applied for cryptography, biothiol detection, and designing logic gates. This work offers a promising method for the synthesis of nanomaterials with multiapplications.

As a self-powered device, triboelectric fiber-generators (TEFGs) have garnered considerable attention over the past decade, overcoming the limitations of conventional power sources. Significantly, while both structures function, the aligned nanofiber film demonstrably outperforms the random nanofiber film in triboelectric output performance. Hence, a triboelectric all-nanofiber generator with an aligned structure is investigated, consisting of the co-electrospun polyacrylonitrile (PAN)/thermoplastic polyurethane (TPU) nanofiber positive triboelectric layer and polyvinylidene fluoride (PVDF)/polydimethylsiloxane (PDMS) nanofiber negative triboelectric layer. After the optimization of structure, triboelectric fiber-generators with aligned (A-TEFG) exhibited peak-to-peak voltage, current output, and transient power density values of 55 V, 0.8 μA, and 33.6 mW/m 2 , respectively, which could efficiently harvest mechanical energy to power light-emitting diodes (LEDs). Furthermore, A-TEFG was used as self-powered sensors for human movement monitoring and transmitting encrypted information followed Morse code principles. Based on the simple and scalable fabrication methods, A-TEFG makes a promising candidate to developing practical, flexible, and self-powered wearable electronic devices.

Integrated circuit anti-counterfeiting based on optical physical unclonable functions (PUFs) plays a crucial role in guaranteeing secure identification and authentication for Internet of Things (IoT) devices. While considerable efforts have been devoted to exploring optical PUFs, two critical challenges remain: incompatibility with the complementary metal-oxide-semiconductor (CMOS) technology and limited information entropy. Here, we demonstrate all-silicon multidimensionally-encoded optical PUFs fabricated by integrating silicon (Si) metasurface and erbium-doped Si quantum dots (Er-Si QDs) with a CMOS-compatible procedure. Five in-situ optical responses have been manifested within a single pixel, rendering an ultrahigh information entropy of 2.32 bits/pixel. The position-dependent optical responses originate from the position-dependent radiation field and Purcell effect. Our evaluation highlights their potential in IoT security through advanced metrics like bit uniformity, similarity, intra- and inter-Hamming distance, false-acceptance and rejection rates, and encoding capacity. We finally demonstrate the implementation of efficient lightweight mutual authentication protocols for IoT applications by using the all-Si multidimensionally-encoded optical PUFs.

The smart materials with multi-color and stimuli-responsive luminescence are very promising for next generation of optical information encryption and anti-counterfeiting, but these materials are still scarce. Herein, a multi-level information encryption strategy is developed based on the polychromatic emission of Sb-doped double perovskite powders (SDPPs). Cs 2 NaInCl 6 :Sb, Cs 2 KInCl 6 :Sb, and Cs 2 AgInCl 6 :Sb synthesized through coprecipitation methods exhibit broadband emissions with bright blue, cyan, and orange colors, respectively. The information transmitted by specific SDPP is encrypted when different SDPPs are mixed. The confidential information can be decrypted by selecting the corresponding narrowband filter. Then, an encrypted quick response (QR) code with improved security is demonstrated based on this multi-channel selection strategy. Moreover, the three types of SDPPs exhibit three different water-triggered luminescence switching behaviors. The confidential information represented by Cs 2 NaInCl 6 :Sb can be erased/recovered through a simple water spray/drying. Whereas, the information collected from the green channel is permanently erased by moisture, which fundamentally avoids information leakage. Therefore, different encryption schemes can be designed to meet a variety of encryption requirements. The multicolor and stimuli-responsive luminescence greatly enrich the flexibility of optical information encryption, which leaps the level of security and confidentiality.

Optical encryption is a potential scheme for information security that exploits abundant degrees of freedom of light to encode information. However, conventional encryption based on fluorescent materials faces challenges in handling complex secret information. Alternatively, single-pixel imaging (SPI) provides a computational modality to solve these problems. In this study, a high-capacity fluorescence encryption scheme, achieved by introducing lanthanide materials and steganography into the encoding and decoding processes of SPI is proposed. Two types of well-designed lanthanide luminescent materials are utilized and excited to generate fluorescence images (fluo-images), which are crucial in this scheme. Various practical experiments using fluo-images as secret keys demonstrate the robustness, effectiveness, and repeatability of this scheme. Furthermore, multi-image experiments indicate the potential of this method to increase secret information capacity. Thus, the proposed fluorescence encryption scheme does provide an efficient computational encryption strategy based on lanthanide luminescent materials for information security, which can improve the security of traditional optical encryption and simultaneously enhance the flexibility of SPI computational decryption.

Traditional encryption technologies using single-fluorescent materials are increasingly vulnerable to attacks due to their predictable responses to stimuli. Furthermore, conventional waterborne polyurethane (WPU) film fabrication methods, such as casting, suffer from long drying times and inconsistent thickness, limiting scalability for advanced applications. To address these issues, we developed cephalopod-inspired WPU composite films that integrate 6,7-dihydroxy coumarin (6,7-CU) and perylene tetracarboxylic acid (PTCA) as fluorophores in segregated layers. This colloidal system achieves good emulsion stability and interfacial interactions, which play a crucial role in the films' complex functionality. The dyes’ hydroxy and carboxylic acid groups strengthen both optical properties and mechanical strength of WPU, achieving a tensile strength of 24 MPa in a 100 μm thin film. Using the electrochemical demulsification-induced fast solidification (DIFS) method, we achieved rapid drying and uniform film formation, overcoming the limitations of traditional casting. This method leverages controlled interfacial dynamics to produce films with sophisticated multicolor responses and improved encryption complexity. Density functional theory (DFT) calculations further reveal the films' stimuli-responsiveness, providing insights into the influence of interfacial mechanisms on their reversible color transformations under UV light and pH changes. Applications in data engraving and QR code labeling demonstrate the films' potential in secure information encryption and anti-counterfeiting technologies.

The widespread application of optical encryption materials with difficult imitation, multicolor-tunable emission and simple operation presents a promising strategy for secure communication and authentication of information. Herein, Eu-MOF grafted with coumarin 7 is successfully constructed through self-assembly process and a prismatic three-dimensional hyperbranched structure is formed. At room temperature, it can be excited to by ultraviolet light significantly different green and red light emission. With the temperature rising to 363 K, under the excitation of 360 nm, a continuous and programmable color transformation occurs, resulting in a fitted line with a fitting degree of 0.99745. In order to maintain robust reliability, regular alterations in accordance with temperature variations are assessed through temperature sensitivity, and the absolute sensitivity and relative sensitivity can reach up to 6.168 % K −1 and 4.387 % K −1 . Based on the abundant emission modes, we develop an asymmetric information security authentication program to simulate encrypted information communication, which provides reliable guidance on visualized information storage and encryption.

Information security is of great importance for modern society with all things connected. Physical unclonable function (PUF) as a promising hardware primitive has been intensively studied for information security. However, the widely investigated silicon PUF with low entropy is vulnerable to various attacks. Herein, we introduce a concept of bionic optical PUFs inspired by unique biological architectures and fabricate four types of bionic PUF by molding the surface micro–nano structures of natural plant tissues with a simple, low-cost, green and environmentally friendly manufacturing process. The laser speckle responses of all bionic PUFs are statistically demonstrated to be random, unique, unpredictable and robust enough for cryptographic applications, indicating the broad applicability of bionic PUFs. Based on this, the feasibility of implementing bionic PUFs as cryptographic primitives in entity authentication and encrypted communication is experimentally validated, showing its potential in future information security applications.

Segregation is a phenomenon of inhomogeneous distribution of constituent elements during crystallization and could be found in alloy, polymers, colloid, etc. Some researchers have also found component segregation in perovskite crystals. Until now, the existing research reports are all about the halogen segregation of perovskite at the micro level, while the research about the component segregation of perovskite at the macro level is blank, leaving no relevant application developed. Therefore, we can broaden the PUFs-based application of perovskite crystals by employing the multi-wavelength emission property arising from component macrosegregation. We synthesized perovskite crystal arrays with macroscopic composition segregation in one step by surface-tension-confined evaporative self-assembly. The macrosegregation in perovskite crystals prepared with different halogen ratios and temperature was surveyed. The photoluminescence spectra of perovskite crystals were investigated. Perovskite crystals with composition segregation could generate physically unclonable cryptographic primitives, which were made by a simple and random process and difficult to replicate. According to the number of peaks in the spectrum, we converted the optical response into quaternary cryptographic keys, and demonstrated the randomness and stability of the system. This study excavated the application prospect of macroscopic component segregation perovskite in all-photonic cryptographic primitives.
