Silver nanoparticles (AgNPs) can be used to treat many clinical challenges due to their resourceful medicinal properties present in them. Moreover, AgNPs exhibits unique optoelectronic properties, distinct chemistry, high surface-to-volume ratio, and high avidity, making them principally suitable for healthcare applications. In the present perspective, size and shape-based AgNPs antimicrobial action are reviewed. Furthermore, the intrinsic features and plausible toxicity of AgNPs with emerging applications across daily life and healthcare categories are discussed. This perspective urges researchers to focus on the hazards of AgNPs before their utilization to deal with human diseases. Moreover, additional studies have been suggested concerning the sustainable engineering of nanoparticles toward safety and quality in human health complications. All these concerns are still considered a challenge because nanoparticle characterization is still in its infancy for implementation in human life. Finally, this perspective provides a scientific foundation for the construction of global accord guidelines in the future.

“…The smooth fracture surface morphology of CG film in Figure 1d indicated the well compatibility between CS and GA, and with the incorporation of ZnO/PAL, the unique nanorods can be observed in the form of not only rods but also bundles, revealing the presence ZnO/PAL nanorods in CG matrix, but did not achieve the desirable blending, which can be attributed to the intermolecular interaction between ZnO/PAL nanorods and the matrix [53]. The dispersion of clay fillers in polymer matrix plays a crucial effect on the physicochemical properties of the films, as confirmed by Mohamed et al [54]. It can be found that with the increased amount of nanorods, the folds of the films increased accordingly, some cracks and aggregations appeared at the same time, which may negatively influence the mechanical properties for its stress defects (the decreased EB at mechanical properties).…”

The synergistic effect of chitosan (CS), glycyrrhizic acid (GA) and ZnO/palygorskite (ZnO/PAL) as potential wound dressing was evaluated in the form of films by the solution casting method. The nanocomposite films were well-characterized with ATR-FTIR, XRD and SEM to explore the interactions between CS, GA and ZnO/PAL. Physical, mechanical and antibacterial properties of the nanocomposite films were systematically investigated for their reliability in end-up utilization. Importantly, it was found that the presence of PAL in the films provided enhanced mechanical properties, whereas CS, GA and ZnO supplied a broad-spectrum antibacterial activity, especially for drug-resistant bacteria such as ESBL—E. coli and MRSA. Overall, this research demonstrated that the prepared films can be a promising candidate for wound-care materials.

Silver nanoparticles (AgNPs) represent one of the most explored categories of nanomaterials for new and improved biomaterials and biotechnologies, with impressive use in the pharmaceutical and cosmetic industry, anti-infective therapy and wound care, food and the textile industry. Their extensive and versatile applicability relies on the genuine and easy-tunable properties of nanosilver, including remarkable physicochemical behavior, exceptional antimicrobial efficiency, anti-inflammatory action and antitumor activity. Besides commercially available and clinically safe AgNPs-based products, a substantial number of recent studies assessed the applicability of nanosilver as therapeutic agents in augmented and alternative strategies for cancer therapy, sensing and diagnosis platforms, restorative and regenerative biomaterials. Given the beneficial interactions of AgNPs with living structures and their nontoxic effects on healthy human cells, they represent an accurate candidate for various biomedical products. In the present review, the most important and recent applications of AgNPs in biomedical products and biomedicine are considered.
