“…AMNPs consist of a range of materials; they may comprise a single element, a mixture of two or more elements, e.g., metal oxides, the combination of a metal element and oxygen. Furthermore, intermetallic and alloys are compounds composed of a combination of two or more metals or another element bonded together to form a defined stoichiometry structure [70,71].…”

Antibiotic resistance is a major threat to public health, which contributes largely to increased mortality rates and costs in hospitals. The severity and widespread nature of antibiotic resistance result in limited treatments to effectively combat antibiotic-resistant pathogens. Nanoparticles have different or enhanced properties in contrast to their bulk material, including antimicrobial efficacy towards a broad range of microorganisms. Their beneficial properties can be utilised in various bioengineering technologies. Thus, antimicrobial nanoparticles may provide an alternative to challenge antibiotic resistance. Currently, nanoparticles have been incorporated into materials, such as fibres, glass and paints. However, more research is required to elucidate the mechanisms of action fully and to advance biomedical applications further. This paper reviews the antimicrobial efficacies and the intrinsic properties of different metallic nanoparticles, their potential mechanisms of action against certain types of harmful pathogens and how these properties may be utilised in biomedical and healthcare products with the aim to reduce cross contaminations, disease transmissions and usage of antibiotics.

“…The finding suggests antibacterial application of Ag/Ni against S. pyogenes and E. coli and antifungal agent against C. albicans. Bimetallic Cu-Ni NPs showed a bacteriostatic effect against S. aureus, E. coli and S. mutan [20]. According to [21], the insecticidal activity of Ag nanoparticles against the A. nerii was investigated.…”

Aims: Nanoparticles are gradually gaining wide scientific interest due to their various applications in catalysis, magnetism, medicine, optics, as antibacterial and nanolarvicidal agents. This research aimed at evaluating the larvicidal activity of green synthesized Ag/Ni BMNPs from the aqueous root extract of Borassus aethiopum as the stabilizing agent as well as their spectroscopic investigation using UV-Visible and FT-IR spectroscopy. Place and Duration of Study: The study was conducted in Gombe State University between August and December, 2019. Methodology: In this study, Ag/Ni hybrid bimetallic nanoparticles was synthesized using an eco-friendly method from the secondary metabolites of Borassus aethiopum acting as the reducing agent. Results: Optical measurements using UV-Vis showed the maximum absorption wavelength at 410nm while the FT-IR result for the root extract showed peaks at 3443.26cm-1, 2929.48 cm-1, 1651.28 cm-1, and 1080.12 cm-1 corresponding to OH stretch, sp3 C-H stretch, C=C stretch and C-O-C stretching respectively. These were replaced in the spectra of the BMNPs with the absence and appearance of some others indicating that they were involved in the capping process. The lethal concentration (LC50) was found to be 5.730, 13.585 and 15.735 mg/L for 1st, 2nd and 3rd/4th instars respectively. Also, the lethal concentration (LC90) was found to be 88.444, 195.689 and 236.889 mg/L for 1st, 2nd and 3rd/4th instars respectively. Conclusion: The larvicidal bioassay result showed a dose-dependent mortality rates against Culex quinquefasciatus larvae which suggest they can be developed to control the insect population.
