Peptides are a class of powerful molecules and building blocks similar to DNA. However, peptides with composition diversity and molecular recognition ability are rarely used for multipurpose integrated applications (especially in sensing, information processing, communication, and security). Herein, peptide-based sensing of Pb 2+ , logic computing, information encoding, and security applications were comprehensively demonstrated. Our fluorescently labeled Pb 2+ -binding peptide exhibited different responses to various metal ions but was specific to Pb 2+ , which were attributed to the fluorescence static quenching and the transformation of the peptide conformation induced by Pb 2+ . This peptide probe was successfully used to quantitatively detect Pb 2+ (detection limit 3.38 nM) in actual water samples and to perform logic calculations. In addition, due to natural concealment of molecules, encoding, encryption, and hiding of 2 kinds of dimensional information (such as text and images), were displayed by using peptide sequences and its selectivity. This information encoding method based on molecules and their subsidiary properties shows great flexibility and scalability and provides a new option for information representation and protection. Inspired by this idea, more interesting and creative molecular sensing and information systems will be developed to promote connectivity, programmability, and intelligence of the molecular world.

The assembly of colloidal particles into micro-patterns is essential in optics, informatics, and microelectronics. However, it is still a challenge to achieve quick, reversible, and precise assembly patterns within micro-scale spaces like droplets. Hereby, a method is presented that utilizes in-plane dielectrophoresis to precisely manipulate particle assemblies within microscale droplets. The electro–microfluidic particle assembly platform, equipped with ingenious electrode designs, enables the formation of diverse micro-patterns within a droplet array. The tunability, similarity, stability, and reversibility of this platform are demonstrated. The ability to assemble letters, numbers, and Morse code patterns within the droplet array underscores its potential for information encoding. Furthermore, using an example with four addressing electrodes beneath a droplet, 16 distinct pieces of information through electrical stimuli is successfully encoded. This unique capability facilitates the construction of a dynamic electronic token, indicating promising applications in anti-counterfeiting technologies.

Janus photonic microobjects have shown great potential in various fields due to their anisotropic shapes and tunable optical properties. Microfluidics is useful for constructing such photonic microobjects. The traditional method of injecting different colloidal photonic streams toward anisotropic multiple stopband photonic microobjects involves complicated and time-consuming procedures. Herein, an easy yet effective approach to fabricate Janus photonic microobjects with dual stopbands from a single stream of photonic components is proposed. A microfluidic device is used to prepare bullet-like, single-stopband photonic microobjects by virtue of the microchannel’s confinement effect. Both the size and shape are readily regulated by adjusting the flow rate of the continuous phase. Under the protection of the desired region of the photonic microobjects with polystyrene (PS) film or silicone tube, the other region is selectively etched to generate a new photonic part. The Janus photonic microobjects with dual stopbands are achieved thereby. Precision control of the protection position of the single-stopband photonic microobjects provides the flexibility to achieve photonic microobjects with various segmental combinations. The porous structure at the etched region is conducive to further functionalization, for example, fluorescence performance, by filling polymers. The resultant photonic microobjects with strong information-encoding characteristics are promising in display and anticounterfeiting.

In this study, we prepared a multicolor structural–fluorescent CdS–PEGDA photonic crystal hydrogel (SFC-CPH) with a dual display mode, which has two different optical states: structural color mode and fluorescent color mode. SFC-CPH displays structural color mode under visible light and fluorescent color mode under ultraviolet light. Initially, monodisperse CdS colloidal particles were synthesized via a hydrothermal method, leading to the self-assembly of a photonic crystal template. The high refractive index of CdS contributes to the photonic crystals’ low-angle dependence and vivid structural colors. Then, a variety of fluorescent molecules were doped into poly(ethylene glycol) diacrylate (PEGDA) hydrogel and combined with photonic crystals with distinct structural colors to prepare three distinct colors of SFC-CPH. We also investigated the optical characteristics and surface properties of these photonic crystal hydrogels. Based on these dual-mode display characteristics, we designed several dual-mode display patterns and a method for information encoding. The unique property of this photonic crystal hydrogel material suggests its substantial potential for applications in information storage, security, and encoding, offering innovative avenues in the realm of information display.

The composite materials combining quantum dots (QDs) and photonic crystals (PCs) could produce complex and high-dimensional anti-counterfeiting patterns, which solves the problems of simple coding information and a low anti-counterfeiting level of monochromatic materials. Herein, we reported a novel hybrid hydrogel made up of CdTe QDs and SiO2 PCs for optical anti-counterfeiting and information encryption–decryption. The hybrid hydrogel was prepared by adding CdTe QDs and gelatin-methacryloyl (GelMA) precursor filler into a poly(ethyleneglycol) diacrylate (PEGDA)-based inverse opal hydrogel. Firstly, GelMA-based pregel and CdTe QDs were photo-cured to obtain patterned fluorescent labels, whose fluorescence intensities were greater than those of the single CdTe QD solution. Then, the PEGDA-based inverse opal hydrogel and hybrid hydrogel containing CdTe QDs and SiO2 PCs were prepared, both of which had angular dependence of structural colors and good water wettability. The hybrid hydrogel had a double optical anti-counterfeiting function because it also had fluorescence characteristics under UV light. Moreover, through a simple combination of CdTe QDs and PCs, more complex and higher-dimensional optical composite coding effects were achieved, providing a good single platform for exploring the combination effects. In addition, the preparation process was simple and flexible, which only need to provide visually confused structural and fluorescence color, such as our patterned “100”. Then, the hidden signal could be quickly identified by relevant spectral detection. Therefore, this work offers a simple avenue for encoding complex information from a single hybrid hydrogel platform and provides a method for rapid information decoding.

The development of a luminescent material with visualized afterglow plays a crucial role in information security. Herein, a long-lived phosphor, KCaF3:Yb3+,Mn2+, with a visualized photon upconversion (UC) afterglow is presented. The UC emission spectrum consists of a high color purity (∼99.33%) yellow emission band peaking at ∼570 nm, and the UC afterglow signal can be observed by the naked eye in both bright and dark fields even at a high temperature of 200 °C. Moreover, the demonstration background and pigments have little influence on the UC afterglow identification. The density functional theory (DFT) calculations and the up-/down-conversion luminescence characteristics suggest that the UC afterglow originates from the long-lived exchange coupled Yb3+–Mn2+ dimers formed in KCaF3:Yb3+,Mn2+, which is independent of the conventional “afterglow trap”. The random distribution characteristics of Mn2+, and the oxygen ion (O2−) introduced by Yb3+ non-equivalent doping are the key factors for forming the efficient UC emission center in this system. Using the photon UC afterglow phosphor in screen printing ink, a visualized information encoding/decoding prototype suitable for both human and machine fast identification is demonstrated.

Peptides have higher information density than DNA and equivalent molecular recognition ability and durability. However, there are currently no reports on the comprehensive use of peptides’ recognition ability and structural diversity for sensing, logic computing, information coding, and protection. Herein, we, for the first time, demonstrate peptide-based sensing, logic computing, and information security on the antimonene platform. The molecular recognition capability and structural diversity (amino acid sequence) of peptides (Pb2+-binding peptide DHHTQQHD as a model) adsorbed on the antimonene universal fluorescence quenching platform were comprehensively utilized to sense targets (Pb2+) and give a response (fluorescence turn-on) and then to encode, encrypt, and hide information. Fluorescently labeled peptides used as the recognition probe and the information carrier were quenched and hidden by the large-plane two-dimensional material antimonene and specifically bound by Pb2+ as the stego key, resulting in fluorescence recovery. The above interaction and signal change can be considered as a peptide-based sensing and steganographic process to further implement quantitative detection of Pb2+, complex logic operation, information coding, encrypting, and hiding using a peptide sequence and the binary conversion of its selectivity. This research provides a basic paradigm for the construction of a molecular sensing and informatization platform and will inspire the development of biopolymer-based molecular information technology (processing, communication, control, security).

Facing the significant challenges of information security, this work proposes an information encoding system based on the fluorescence properties of metal-ion-induced polystyrene-block-poly(acrylic acid) (PS–PAA) nanoaggregates (MIPAs), in which Eu3+, Tb3+, and Al3+ ions are embedded. By adding poly(vinylpyrrolidone) (PVP), red, green, and blue primary color inks are obtained. By precisely adjusting the ratio of cations, the control of photoluminescence (PL) intensity at different emission wavelengths is achieved, thereby obtaining a full-color fluorescent ink. Under the potential driving force in the nozzle of an electrofluidic inkjet printer, the ink can be printed onto a paper substrate and exhibit multiple fluorescent colors under ultraviolet (UV) irradiation. The printed fine image structures can carry encoded data. In these images, the multiple emission modes of fluorescent nanoaggregates induced by metal ions (Eu3+, Tb3+, and Al3+) can be combined with multiple quenching mechanisms. This will hopefully further improve the security of encoded information and the efficiency of information retrieval.

In the domain of digital data exchange, ensuring information security is the supreme demand for data storage and transmission. Interlinking cryptographic techniques with steganographic principles can enhance data confidentiality. However, there have been no reports thus far to develop molecular platforms for hybrid crypto-steganography systems. Using our synthesized nanoclusters (BSA-Au/Ag NCs) through bovine serum albumin (BSA) as a versatile scaffold, we fabricated a molecular platform for concatenated logic circuits and molecular keypad lock. Then, we integrate terrestrial direction information transmission through molecular navigation, employing a double block cipher by combining stego key and shifting cipher key techniques to develop a hybrid crypto-steganography system, aimed at enhancing security paradigms. Furthermore, we prioritize information protection by developing an enhanced distress call protocol using a polyalphabetic cipher to activate covert communication capabilities, thereby safeguarding data against potential infiltrators.

Various sensing platforms based on molecular or nanosystems are widely exploited through molecular diversity and specific recognition. However, it is extremely challenging to develop systems with tunable sensing ability and utilize the systems as information carriers/covers for communication and safety. Herein, DNA nanosensing systems based on cobalt oxyhydroxide (CoOOH) nanosheets were constructed for tunable detection and valence distinction of metal ions , molecular crypto-steganography, and information coding. CoOOH nanosheets absorb fluorescence-labeled single-stranded DNA with different bases and lengths, resulting in fluorescence quenching . The binding priority of bases with CoOOH nanosheets was guanine (G) > cytosine (C) > adenine (A) ≈ thymine (T) and the short chain excelled long chain. Due to the differences in the interaction among CoOOH, DNA, metal ions and variability of DNA bases, various DNA−CoOOH nanosystems have significantly different selective response patterns (that is selectivity) to metal ions and tunable linear ranges to Fe 3+ , Hg 2+ , Cr 3+ . Interestingly, by utilizing their molecular diversity, recognition, selective patterns, DNA−CoOOH sensing systems can be served as doubly cryptographic and steganographic systems to implement information encoding, encryption, and hiding and to reversely improve the selectivity of metal ions. This study provides an idea and platform for adjustable detection and valence distinction of metal ions, and gives a set of “molecular programming languages” for designing intelligent programmable sensing and molecular information communication and safety systems.

Circularly polarized room-temperature phosphorescence (CPRTP) is of paramount importance for applications in information encoding, bioimaging, and optoelectronic devices, however, it remains challenging to organize highly efficient CPRTP materials with controlled handedness and long afterglow. Herein, as an outstanding novel finding, it is diclosed that ultralong CPRTP with on-demand chiroptical properties is simple to realize using the earth-abundant cellulose and silica. It is shown that left-handed chiral nematic nanoporous silica films featuring defect photoluminescence enable ultralong CPRTP with an unprecedented control of the handedness. This work presents that the chiral nematic nanoporous silica films display right-handed CPRTP and left-handed CPRTP with the phosphorescence dissymmetry factors up to −0.130 and 0.093 as well as the afterglow lifetimes of 1.094 and 0.949 s, respectively. The potential of the transparent chiral nematic nanoporous silica films, capable of ultralong CPRTP and selective reflection of left-handed circularly polarized light, for the development of anticounterfeiting optical labels is showcased. This work presents a versatile strategy and a step toward the development of ultralong CPRTP materials with on-demand chiroptical properties from readily available defect phosphors for photonic applications.

Inspired by the emergent functions of molecular interactions and signal processing networks in living systems, exploring the multifunctional properties and perceptual capabilities of molecular or nanosystems and digitizing their signal responses and interaction networks remains a key challenge. Here, multifunctional antimonene-gold nanocomposites (AM-Au NCs) were synthesized efficiently and conveniently and applied in molecular sensing and digital applications, including multi-component detection and multi-coding information protection. After mixing surfactant, AM, Au 3 ⁺ and NaBH₄, AM-Au NCs with dispersed Au nanoparticles on AM nanosheets, exhibiting prominent Au plasmonic absorption. This endows NCs with unique broad-spectrum fluorescence quenching abilities, facilitating the development of fluorescence sensing platforms with dyes and fluorescence-labeled aptamers for selective and sensitive detection of metal ions and tumor biomarkers (CD63 and tumor-derived exosomes), even in real samples. Through binary or digital encoding of the selective responses and diverse DNA sequences of these sensing systems, a series of molecular encryption and hiding techniques are presented and applied to the molecular-level conservation of special text information. This work provides a new framework for the preparation and multifunctional use of two-dimensional nanocomposites, paving the way for greater integration of molecular sensing and information technology.
