Nanozymes exhibit significant potential in medical theranostics, environmental protection, energy development, and biopharmaceuticals due to their exceptional catalytic performance. Compared with natural enzymes, nanozymes have the advantages of simple preparation and purification, convenient production and low cost. Therefore, it is very important to prepare nanozymes quickly and efficiently, which not only helps to expand their application scope, but also can further exert their great potential in various fields. Metal-organic frameworks (MOF) materials serve as versatile substrates for constructing nanozymes, offering unique advantages like adjustable structure, high specific surface area, and porous channels. MOF coordination nodes constructed from metal ions or metal clusters have unique properties that can be leveraged to tailor nanozyme characteristics for different applications. This review describes and analyzes recent methods for constructing nanozymes using MOF materials, and explores their application prospects in biomedicine. By expounding the preparation techniques and biomedical applications of nanozymes, this review aims to inspire researchers to develop innovative nanozyme materials and explore new application directions.

This paper presents an all-optical 4 × 2 encoder based on graphene-plasmonic waveguides for operation in the wavelength range of 8-12 μm. The basic plasmonic waveguide consists of a silicon (Si) strip and a graphene sheet supported by two dielectric ridges. Surface plasmon polaritons (SPPs) are stimulated in the spatial gap between the graphene sheet and the Si strip.

Combining bright-field and edge-enhanced imaging affords an effective avenue for extracting complex morphological information from objects, which is particularly beneficial for biological imaging. Multiplexing meta-lenses present promising candidates for achieving this functionality. However, current multiplexing meta-lenses lack spectral modulation, and crosstalk between different wavelengths hampers the imaging quality, especially for biological samples requiring precise wavelength specificity.

This letter commends the recent innovative research findings on "Dual-Action Antifungal Peptide Nanozymes: A Novel Approach to Combatting Antimicrobial Resistance." The study introduces a pioneering method to address antimicrobial resistance by developing peptide nanozymes that mimic antimicrobial peptides and enzymes through de novo design and peptide assembly. The heptapeptide IHIHICI, designed using AlphaFold2 and molecular dynamics simulations, exhibits high stability and dual antifungal actions, effectively killing over 90% of Candida albicans within 10 min.

Recent examples of immune responses directed against the synthetic polymer poly(ethylene glycol) (PEG) have led to the development of biocompatible polymers, which are viewed as promising candidates to act as surrogate materials for use in biological applications, such as hydrophilic poly(2-oxazoline)s (POx). Despite this, the characterization of critical aspects of the immune response against these emerging materials is sparse, in part because no known monoclonal antibodies (mAbs) against this family of synthetic material have been reported. To advance the understanding of such responses, we report the successful isolation and characterization of hybridoma-derived mAbs with excellent specificity for different POx species and notable selectivity for highly branched polymer architectures over linear systems.

RNA interference (RNAi) is a biological process in which RNA molecules are involved in sequence-specific suppression of gene expression, via small RNA triggers derived from double-stranded RNA that can target specific genes; it is a natural process that plays a role in both the regulation of protein synthesis and in immunity. Discovery of RNAi by Fire and Mello in 1998 had a profound impact on unraveling novel aspects of eukaryotic biology. RNA interference (RNAi) has proven to be an immensely useful tool for studying gene function and validation of potential drug targets in almost all organisms.
