“…These favorable properties are due to multifunctional or synergistic effects produced by the three metals present in the same system [ 20 ]. The addition of a third metal or metal oxide into the composite supposedly generates a combinatorial effect and introduces several possibilities for different morphologies, structures, and chemical compositions to improve catalytic activity, selectivity, and specific performance [ 63 ]. Trimetallic NPs exhibit improved reactivity because of the electronic and synergistic effects of the different elements and the geometric arrangements of the metal surrounding the absorbing atoms.…”

“…Recently, FeCoNi mixed oxide NPs supported on oxidized MWCNTs were used as catalysts for oxygen reduction and oxygen evolution reactions, and they demonstrated enhanced selectivity with respect to the reduction of O 2 to OH− when compared with FeNi, FeCo, and CoNi bimetallic catalysts, thus suggesting synergistic effects among the metal oxide elements [ 65 ]. Similarly, the antimicrobial activity of trimetallic NPs shows synergistic effects when compared with bi- and trimetallic NPs, as shown in Table 2 [ 63 , 88 , 89 , 90 , 91 ]. Therefore, greater attention has been paid to synergistic interactions or combinatorial therapy as an alternative strategy to combat antibiotic-resistant infectious pathogens.…”

Recently, infectious diseases caused by bacterial pathogens have become a major cause of morbidity and mortality globally due to their resistance to multiple antibiotics. This has triggered initiatives to develop novel, alternative antimicrobial materials, which solve the issue of infection with multidrug-resistant bacteria. Nanotechnology using nanoscale materials, especially multimetallic nanoparticles (NPs), has attracted interest because of the favorable physicochemical properties of these materials, including antibacterial properties and excellent biocompatibility. Multimetallic NPs, particularly those formed by more than two metals, exhibit rich electronic, optical, and magnetic properties. Multimetallic NP properties, including size and shape, zeta potential, and large surface area, facilitate their efficient interaction with bacterial cell membranes, thereby inducing disruption, reactive oxygen species production, protein dysfunction, DNA damage, and killing potentiated by the host’s immune system. In this review, we summarize research progress on the synergistic effect of multimetallic NPs as alternative antimicrobial agents for treating severe bacterial infections. We highlight recent promising innovations of multimetallic NPs that help overcome antimicrobial resistance. These include insights into their properties, mode of action, the development of synthetic methods, and combinatorial therapies using bi- and trimetallic NPs with other existing antimicrobial agents.

“…The method involves simultaneous reduction of precursor salts CuSO 4 •5H 2 O, Ni(NO 3 ) 2 •6H 2 O and Cr(NO 3 ) 3 •9H 2 O with the C. sativum extract [16]. Typically, 0.01M of salt solution comprising all three metals was mixed with the leaf extract in 250 mL Erlenmeyer flask.…”

The tri-metallic oxide Ni/Cr/Cu nanoparticles (NPs) were synthesized using Coriander sativum extract as the reducing agent. The precursors namely CuSO4.5H2O, Ni(NO3)2·6H2O and Cr (NO3)3·9H2O were used for the green synthesis. Further, the prepared NPs were characterized using Ultraviolet-Visible (UV-Vis) spectroscopy and X-ray diffraction (XRD) studies. Its antimicrobial property against two fungal and two bacterial species was determined by measuring the respective zone of inhibition (ZOI) in well diffusion method. A dose dependent inhibition was observed in all the four species of pathogens including Escherichia coli, Staphylococcus aureus, Aspergillus flavus and Penicillium sp. This antimicrobial property of tri-metallic oxide NPs may be utilized in the field of medical research, pharmaceutical industries and environmental sciences.

“…Additionally, Au-ZnO-Ag trimetallic NPs (~20 nm) have been bio-prepared using the extract of Meliloti officinalis [ 86 ]. In another study, a reliable procedure was reported for the biosynthesis of Cu/Cr/Ni trimetallic oxide nanomaterials by applying Froriepia subpinnata and Eryngium campestre (aqueous leaf extracts) under mild temperature conditions [ 87 ]; these NPs exhibited superb antibacterial activities versus E. coli and Staphylococcus aureus. The optimized conditions for E. campestre leaf extract were 3 min reaction time, at 34 °C and metal salt-to leaf extract ratio of 2.38 with 73% yield.…”

“…The optimized conditions for E. campestre leaf extract were 3 min reaction time, at 34 °C and metal salt-to leaf extract ratio of 2.38 with 73% yield. The corresponding value for F. subpinnata leaf extract was 3 min at 40 °C, and the ratio of metal salt to leaf extract was 1.07; 72% of the conversion of salt into trimetallic oxide NPs was evaluated by modeling software [ 87 ].…”

Nanoparticles (NPs) and multifunctional nano-sized materials have significant applications in diverse fields, namely catalysis, sensors, optics, solar energy conversion, cancer therapy/diagnosis, and bioimaging. Trimetallic NPs have found unique catalytic, active food packaging, biomedical, antimicrobial, and sensing applications; they preserve an ever-superior level of catalytic activities and selectivity compared to monometallic and bimetallic nanomaterials. Due to these important applications, a variety of preparation routes, including hydrothermal, microemulsion, selective catalytic reduction, co-precipitation, and microwave-assisted methodologies have been reported for the syntheses of these nanomaterials. As the fabrication of nanomaterials using physicochemical methods often have hazardous and toxic impacts on the environment, there is a vital need to design innovative and well-organized eco-friendly, sustainable, and greener synthetic protocols for their assembly, by applying safer, renewable, and inexpensive materials. In this review, noteworthy recent advancements relating to the applications of trimetallic NPs and nanocomposites comprising these NPs are underscored as well as their eco-friendly and sustainable synthetic preparative options.
