“…The key role of the catalyst is to transfer electrons from electron donors to electron acceptors, resulting in an intermediate redox potential that can act as an electron relay to aid electron transfer. 16,22,23 Various nanomaterials have been used as catalysts due to their unique physiochemical properties, as this process is favorable thermodynamically but unfavorable kinetically in the absence of a catalyst. 23−28 These catalysts include silver nanoparticles (Ag-NPs), 29−36 silver-copper oxide nanocomposites, 37 modified Ag-NPs, 38 gold nanoparticles, 39−41 iron oxide nanoparticles, 42 activated carbon, 43 graphene oxide, 44,45 zinc oxide nanoparticles, 46 zirconium oxide, 47 Cu/sodium borosilicate nanocomposite, 48 Pd/calcium lignosulfonate nanocomposite, 49 lignin-derived (nano)materials, 50 palladium nanoparticles, 51,52 and Cu NPs@Fe 3 O 4 .…”

Silver nanoparticles (Ag-NPs) exhibit vast potential in numerous applications, such as wastewater treatment and catalysis. In this study, we report the green synthesis of Ag-NPs using Acacia ehrenbergiana plant cortex extract to reduce cationic Rhodamine B (RhB) dye and for antibacterial and antifungal applications. The green synthesis of Ag-NPs involves three main phases: activation, growth, and termination. The shape and morphologies of the prepared Ag-NPs were studied through different analytical techniques. The results confirmed the successful preparation of Ag-NPs with a particle size distribution ranging from 1 to 40 nm. The Ag-NPs were used as a heterogeneous catalyst to reduce RhB dye from aqueous solutions in the presence of sodium borohydride (NaBH4). The results showed that 96% of catalytic reduction can be accomplished within 32 min using 20 μL of 0.05% Ag-NPs aqueous suspension in 100 μL of 1 mM RhB solution, 2 mL of deionized water, and 1 mL of 10 mM NaBH4 solution. The results followed a zero-order chemical kinetic (R 2 = 0.98) with reaction rate constant k as 0.059 mol L–1 s–1. Furthermore, the Ag-NPs were used as antibacterial and antifungal agents against 16 Gram-positive and Gram-negative bacteria as well as 1 fungus. The green synthesis of Ag-NPs is environmentally friendly and inexpensive, as well as yields highly stabilized nanoparticles by phytochemicals. The substantial results of catalytic reductions and antimicrobial activity reflect the novelty of the prepared Ag-NPs. These nanoparticles entrench the dye and effectively remove the microorganisms from polluted water.

“…The fact that this peak is the distinctive SPR of metallic Ag NP indicates that AgNP-Bo has probably been produced. Also, owing to a plant's lack of metallic SPR, no absorption bands of pure Brassica oleracea leaf extract was seen at a certain wavelength range [24]. XRD analysis: As shown in Figure 2, the XRD examination supported the purity and crystallinity of the AgNP-Bo phase.…”

In this work, biogenic silver nanoparticles (Ag NPs) from Brassica oleracea (Bo) leaf extract (AgNP-Bo) were prepared and utilized in synthetic mixtures for the accurate, effective, and sensitive spectrophotometric detection of Paracetamol. Measurements in the UV-Visible, X-ray diffraction (XRD), and scanning electron microscopy (SEM) have been used to confirm the synthesis of AgNP-Bo. These statistics indicate that the average particle size is 26.39 nm, the crystallinity has an aggregated structure, and the typical absorption wavelength is 445 nm. To decrease the possible influence of the listed water-soluble interference analytes, namely Tyrosine, Alanine, and Leucine, the 2nd order derivative method was used for our investigation. Using complexation with AgNP-Bo, the linear range, limit of detection (LOD), and relative standard deviation (RSD) for Paracetamol were calculated. The obtained values were 0.1-2, 0.09 µM, and 1.06%, respectively. With average percent recovery values of 93.33, 96.67, and 90.00%, respectively, AgNP-Bo also demonstrated excellent performance for Paracetamol detection in synthetic combinations including Tyrosine, Alanine, and Leucine. The suggested technique applied effectively for the quantitative analysis of synthetic mixtures, which makes it possible to employ Ag NPs going forward to determine biological molecules when interfering analytes from actual samples are present. Keywords: Silver nanoparticles; Brassica oleracea; Paracetamol; 2nd order derivative spectrophotometry; Interferences.

Natural Products-Based Metallic Nanoparticles as Antimicrobial Agents

Natural products offer a wide range of bioactivity including antimicrobial properties. There are many reports showing the antimicrobial activities of phytochem icals from plants. However, the bioactivity is limited due to multidrug resistant properties of the microorganism and different composition of cell membrane. The antibacterial activity of the natural products is different toward Gram-negative and Gram-positive bacteria. These phenomena are caused by improper physicochemical conditions of the substance which hinder the phytochemical bioactivity against the broad range of bacteria. One of the strategies to improve the antimicrobial action is by biogenic synthesis via redox balance of the antimicrobial active substance with metal to form nanosized materials or nanoparticles (NPs). Antibiotic resistance is not relevant to NPs because the action of NPs is via direct contact with bacterial cell walls without the need of penetration into microbial cells. The NPs that have shown their effectiveness in preventing or overcoming biofilm formation such as silver-based nanoparticles (AgNPs), gold-based nanoparticles (AuNPs), platinum-based nanoparticles (PtNPs) and Zinc oxide-based nanoparticles (ZnONPs). Due to its considerably simple synthesis procedure has encouraged researchers to explore antimicrobial potency of metallic nanoparticles. Those metallic nanoparticles remarkably express synergistic effects against the microorganisms tested by affecting bacterial redox balance, thus disrupting their homeostasis. In this paper, we discuss the type of metallic nanoparticle which have been used to improve the antimicrobial activity of plant extract/constituents, preparation or synthesis process and characterisation of the plant-based metallic nanoparticles.
