The combination of several modules, including metal nanoparticles (tantalum or zinc), antimicrobial substances, enzyme nanocomplexes that provide self-purification (self-degassing) and multiple functionalization, makes it possible to create materials that provide protection against chemical and biological damaging agents. The purpose of this work is to study the combined effect of metal nanoparticles, other biocidal compounds, and nanosized enzyme complexes of hexidine-containing organophosphate hydrolase and penicillin acylase deposited on unified tissue platforms on organophosphorus compounds and bactericidal activity. Materials and research methods. The protective self-cleaning material was created on the basis of the principle of constructing modular materials with desired properties. Nanosized metal complexes and enzymatic non-covalent polyelectrolyte complexes with polyglutamic acid or antimicrobial peptides were applied to a tissue unified platform in a certain sequence and in a certain amount, and its antitoxic and antimicrobial properties were studied. The discussion of the results. With the simultaneous operation of several modules, subject to certain requirements for applying the quantity and sequence, the properties of the modules are preserved, which do not neutralize or disable the specific properties of the modules and do not interfere with other modules to perform their functions. The best results of such materials can be obtained by combining biologically inert Ta nanoparticles and a stabilized enzyme in a polyelectrolyte complex. To acquire antimicrobial properties, fibrous materials can be functionalized not only by a combination of metal nanoparticles with enzyme preparations, but also by a combination of low molecular weight antibiotics with enzymes. Conclusions. The studies performed have demonstrated the possibility of combining modules containing metal carboxylates, metal nanoparticles, and enzyme nanocomplexes for multiple functionalization of the same fibrous materials, which acquired biocidal and antichemical protective properties. New self-degassing materials have been obtained that have protective chemical and biological properties and high stability in terms of catalytic activity with respect to the main substrates of the introduced enzymes and bactericidal activity. The use of such approaches makes it possible to impart protective properties to almost any fabric or clothing made from it, on which the studied modules will be applied, which will provide the required level of protection for personnel and have a debilitating and chilling effect.

In recent years, there has been a surge in annual plastic production, which has contributed to growing environmental challenges, particularly in the form of microplastics. Effective management of plastic and microplastic waste has become a critical concern, necessitating innovative strategies to address its impact on ecosystems and human health. In this context, catalytic degradation of microplastics emerges as a pivotal approach that holds significant promise for mitigating the persistent effects of plastic pollution. In this article, we critically explored the current state of catalytic degradation of microplastics and discussed the definition of degradation, characterization methods for degradation products, and the criteria for standard sample preparation. Moreover, the significance and effectiveness of various catalytic entities, including enzymes, transition metal ions (for the Fenton reaction), nanozymes, and microorganisms are summarized. Finally, a few key issues and future perspectives regarding the catalytic degradation of microplastics are proposed.
