“…Metal nanoparticles have been proposed as promising candidates for antimicrobial agents. Not only do they possess the ability to induce microbial death or limit growth, but they also exhibit unique physicochemical properties, including a high surface area-to-volume ratio, reactivity, and stability [24,25].…”

Antibiotic-resistant bacteria and associated infectious diseases pose a grave threat to human health. The antibacterial activity of metal nanoparticles has been extensively utilized in several biomedical applications, showing that they can effectively inhibit the growth of various bacteria. In this research, copper-doped polydopamine nanoparticles (Cu@PDA NPs) were synthesized through an economical process employing deionized water and ethanol as a solvent. By harnessing the high photothermal conversion efficiency of polydopamine nanoparticles (PDA NPs) and the inherent antibacterial attributes of copper ions, we engineered nanoparticles with enhanced antibacterial characteristics. Cu@PDA NPs exhibited a rougher surface and a higher zeta potential in comparison to PDA NPs, and both demonstrated remarkable photothermal conversion efficiency. Comprehensive antibacterial evaluations substantiated the superior efficacy of Cu@PDA NPs attributable to their copper content. These readily prepared nano-antibacterial materials exhibit substantial potential in infection prevention and treatment, owing to their synergistic combination of photothermal and spectral antibacterial features.

The COVID‐19 pandemic profoundly changes the perception of the impact of viral diseases on society and the consequent need to develop new and more effective technologies in vaccines and antivirals. Thus, research in the field of antivirals has received a new and strong impetus by considering new approaches and innovative methodologies. One example has been the numerous published studies on antiviral nanosystems developed from nanoparticles, among the most promising of which are carbon dots (C‐dots). C‐dots are effective antivirals due to multiple mechanisms of action. They are also, in general, water‐soluble and noncytotoxic. However, the data reported in the literature are still fragmented and cover different families of viruses and types of C‐dots. Therefore, a comparative study is needed to identify possible strategies for designing C‐dots with antiviral activity. This article aims to provide a comparative and critical analysis of the published data on C‐dots and their antiviral properties against various types of viruses. By exploring the relationship between the composition and properties of C‐dots, this article aims to shed light on the mechanism of their antiviral activity. The review has highlighted the potential of C‐dots as antiviral agents and would serve as a basis for further research in this field.
