“…Moreover, compared to nanomaterials previously reported as antibacterial agents, the biomasses obtained from star anise show a similar antibacterial activity as these nanomaterials, such as sulfonated chitosan-based antibiofilm (Huang et al, 2019) and natural clay nanocomposites (Dong et al, 2020). However, star anise extractives exhibit lower antibacterial activities than that of nanocomposites (TiO 2 /Sb 2 S 3 /GQDs) mixed with graphene quantum dots (GQD) (Teymourinia et al, 2019), but display higher antibacterial efficacy than that of ultra-small copper oxide (II) nanoparticles (Moniri Javadhesari et al, 2019). Therefore, it is indicated that the obtained extractives of star anise can be performed as the antibacterial agents in the biomedical fields.…”

Recently, natural resources have attracted considerable interest for their applications in food security and human health problems. Traditional natural spices, such as star anise and black pepper, played important roles in the pharmaceutical and food industries due to their strong pharmacological activity, antioxidant potential and rare complications. In order to achieve biomasses from the natural product with multiple bioactivities, we developed the multistage extraction method to extract and separate various bioactive compounds from these natural plants. Our work demonstrated that various bioactive-rich extractives were achieved using steam distilled- or oxidative-extraction methods with high extraction yields and purity. Furthermore, the extractives in each step can be used not only as bioactive compounds, but also as a resource to further prepare different derivatives during the next extractive step, providing biomass-saving to a great extent. The extractives obtained with high yields and purities (>82%) were identified by 1H NMR, 13C NMR, FTIR, UV-vis, fluorescence spectroscopy, and high-performance liquid chromatography (HPLC). Moreover, these biomasses display potent antibacterial activities against some types of microorganisms such as S.aureus, S.pyogenes, E.coli, and S.typhi with a lowest MIC of 400 μg/ml for the development of antibacterial agents, significant antioxidant activity as the natural antioxidant for enhancing food shelf-life, and excellent anticancer activity that induces significant cancer cell apoptosis. This work showed the different multistage extracts from natural products, which enable them to be applied in the fields of the pharmaceutical industry and the food industry.

“…Moniri et al synthesized ultra-small CuONPs obtaining a minimum inhibitory concentration (MIC) (derived from both precursors) against E. coli and S. aureus of 3.75 and 2.50 mg/mL, respectively [132]. Ishaque and Kannabiran biosynthesized CuONPs which showed inhibited the bacterial pathogens B. cereus, P. mirabilis and A. caviae even at 5 µg/mL concentration [133].…”

Metal-Based Nanoparticles as Antimicrobial Agents: An Overview

Metal-based nanoparticles have been extensively investigated for a set of biomedical applications. According to the World Health Organization, in addition to their reduced size and selectivity for bacteria, metal-based nanoparticles have also proved to be effective against pathogens listed as a priority. Metal-based nanoparticles are known to have non-specific bacterial toxicity mechanisms (they do not bind to a specific receptor in the bacterial cell) which not only makes the development of resistance by bacteria difficult, but also broadens the spectrum of antibacterial activity. As a result, a large majority of metal-based nanoparticles efficacy studies performed so far have shown promising results in both Gram-positive and Gram-negative bacteria. The aim of this review has been a comprehensive discussion of the state of the art on the use of the most relevant types of metal nanoparticles employed as antimicrobial agents. A special emphasis to silver nanoparticles is given, while others (e.g., gold, zinc oxide, copper, and copper oxide nanoparticles) commonly used in antibiotherapy are also reviewed. The novelty of this review relies on the comparative discussion of the different types of metal nanoparticles, their production methods, physicochemical characterization, and pharmacokinetics together with the toxicological risk encountered with the use of different types of nanoparticles as antimicrobial agents. Their added-value in the development of alternative, more effective antibiotics against multi-resistant Gram-negative bacteria has been highlighted.

“…CuO NPs: These nanoparticles produce reactive oxide (ROS). In other words, the occurrence of a redox cycle (oxidation and reduction) as a result of the loss of glutathione and the effect on sulfhydryl protein groups, destroys DNA and oxidizes and destroys lipids [59]. The combined effect of copper oxide nanoparticles and Nisin also reduces the growth of bacteria [60].…”

The purpose of this research study was to assess the use of nanoparticles in combat pathogenic microorganisms and also to investigate the synergistic effect of nanoparticles with antibiotics in eliminating these factors. In this work, the influence of different nanoparticles on microorganisms was evaluated in 89 studies. It was found that nanoparticles can be used against microorganisms, either independently or by their synergistic effect with antibiotics. The study found that metal nanoparticles have a more antimicrobial effect, among metal nanoparticles, silver nanoparticles exert the most specific among all microorganisms. Meanwhile, metal nanoparticles can be a good alternative to the use of antibiotics and inhibitors of pathogens.
