“…In the present study, green synthesis of ZnO nanoparticles was implemented via adapting the bottom-up mode of synthesis. The methodology employed during the synthesis process was slightly modified from the previous report by Gharpure et al [33] Briefly, 500 ml of aqueous 0.05 M zinc acetate solution was added to a beaker at room temperature. Under stirring conditions, 250 ml of PDL extract was added to the beaker.…”

“…Another major factor influencing the antimicrobial potential is the nature of nutrient medium used to grow micro-organisms. The concentration of free Zn 2+ ions available in the immediate vicinity of microbial cells majorly affects their toxicity [33]. Freely available Zn 2+ ions upon dissociation of ZnO nanoparticles might interact with nitrogen source available in the nutrient medium, thereby resulting in formation of [Zn(NH 3 ) 4 ] 2+ complex.…”

Use of plant extracts for synthesizing zinc oxide (ZnO) nanoparticles is gaining importance due to their easy, eco-friendly, cost effective and non-toxic nature. In this study, an economical biosynthetic approach of ZnO formation was delineated where aqueous extract of Prunus dulcis (almond) leaves has been used as reducing/capping agent followed by their characterization studies. The present study has successfully synthesized pure, highly crystalline in nature, predominantly spherical ZnO nanoparticles within the size range 71-214 nm for nanocystallites and 526 nm-2.37 μm for aggregated flower-shaped ZnO nanoparticles. Microbicidal properties of uncalcined and calcined ZnO nanoparticles were evaluated using test microbes (bacteria: E. coli, S. aureus, P. aeruginosa, B. subtilis; fungi Penicillium spp., F. oxysporum, A. flavus, R. solani). Lack of microbicidal potential was observed against all four bacteria and fungi. When tested for toxicity against HCT-116 carcinoma cells, these nanoparticles displayed non-toxic nature. This biocompatibility is influenced by physico- chemical properties of ZnO nanoparticles as well as biological properties of living cells. Thus, these ZnO nanoparticles can serve as an innocuous machinery in disease therapeutics due to the presence of their non-microbicidal and non-antineoplastic activities.

In the last decades, the idea of green nanotechnology has been expanding, and researchers are developing greener and more sustainable techniques for synthesizing nanoparticles (NPs). The major objectives are to fabricate NPs using simple, sustainable, and cost-effective procedures while avoiding the use of hazardous materials that are usually utilized as reducing or capping agents. Many biosources, including plants, bacteria, fungus, yeasts, and algae, have been used to fabricate NPs of various shapes and sizes. The authors of this study emphasized the most current studies for fabricating NPs from biosources and their applications in a wide range of fields. This review addressed studies that cover green techniques for synthesizing nanoparticles of Ag, Au, ZnO, CuO, Co3O4, Fe3O4, TiO2, NiO, Al2O3, Cr2O3, Sm2O3, CeO2, La2O3, and Y2O3. Also, their applications were taken under consideration and discussed.

“…Metal NPs (NPs) are metals with a density of more than 5 g/cm 3 [ 40 ]. Al (Al 2 O 3 ), Au, Bi, Ce, Cu (CuI, CuO, and Cu 2 O), Fe (Fe 2 O 3 ), Mg (MgO), Ti (TiO 2 ), and Zn (ZnO) are metals that are fabricated to synthesize NPs [ 41 , 42 , 43 , 44 ] which are small in size and have a high surface-to-volume ratio, which impacts the antibacterial activity of NPs [ 40 ].…”

Methicillin-resistant Staphylococcus aureus (MRSA) is an important cause of pneumonia in humans, and it is associated with high morbidity and mortality rates, especially in immunocompromised patients. Its high rate of multidrug resistance led to an exploration of novel antimicrobials. Metal nanoparticles have shown potent antibacterial activity, thus instigating their application in MRSA. This review summarizes current insights of Metal-Containing NPs in treating MRSA. This review also provides an in-depth appraisal of opportunities and challenges in utilizing metal-NPs to treat MRSA.
