“…The decrease in absorption intensity confirms DPPH's good scavenging activities, which are due to its ability to be a good oxidant, electron-losing, and capping agent on the surface of various nanomaterials. Our results show similar contact with Ag 2 O and ZnO NRs using cow urine have different applications in photoluminescence, photolytic, antibacterial, and antioxidant activities as reported previously by Vinay et al 55 and Dabhane et al 51 . Significantly, the biogenic synthesis of Co 3 O 4 NPs and the hydrothermal synthesis of ZnO NRs exhibit a broad spectrum of antibacterial and antioxidant activity.…”

In this study, a novel synthetic method for cobalt oxide (Co3O4) nanoparticles using Bos taurus (A-2) urine as a reducing agent was developed. In addition to this ZnO nanorods were produced hydrothermally and a nanocomposite is formed through a solid-state reaction. The synthesized materials were characterized through modern characterization techniques such as XRD, FE-SEM with EDS, DLS, zeta potential, FT-IR, Raman spectroscopic analysis, and TGA with DSC. The free radical destructive activity was determined using two different methods viz. ABTS and DPPH. The potential for BSA denaturation in vitro, which is measured in comparison to heat-induced denaturation of egg albumin and results in anti-inflammatory effects of nanomaterial was studied. All synthesized nanomaterials have excellent antibacterial properties, particularly against Salmonella typhi and Staphylococcus aureus. The composite exhibits excellent antioxidant and anti-inflammatory activities in comparison to pure nanomaterials. This reveals that these nanomaterials are advantageous in medicine and drug administration.

“…47 It is well recognized that Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli can be employed as markers to comprehend molecular and biological processes, and metallic NPs are better at combating microorganisms than the positive control, which are antibiotics. 15,[48][49][50] NP surfaces can be functionalized, and the interaction of NPs with the bacterial cell wall and membrane can be increased, and thus achieving high antibacterial, anticancer or antioxidant activities with flavonoids, terpenoids, saponins and alkaloids contained in plant extracts, which can be used as reducing and stabilizing agents during the synthesis of NPs. 51 M. charantia is known as a medicinal herb and its antiviral, antibacterial, anti-inflammatory and antitumor potentials have been proved.…”

BACKGROUNDUtilizing the fruit extract of bitter melon (Momordica charantia), zinc nanoparticles (ZnO‐NPs) were synthesized through a green approach, a novel endeavor in current literature. The primary objective was to evaluate the phytotoxic and growth‐promoting effects of these ZnO‐NPs on wheat, chosen as a test plant. Structural characterization using X‐ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy revealed the hexagonal wurtzite crystal structure of ZnO‐NPs and identified spherical M. charantia‐produced (MC)‐ZnO‐NPs ranging in size from 48 to 150 nm.RESULTSAt a concentration of 2000 mg L−1, both MC‐ and raw‐ZnO‐NPs augmented wheat germination percentages. Furthermore, raw‐ZnO‐NPs at 4000 mg L−1 demonstrated the highest chlorophyll content. Despite the plant's increased accumulation of MC‐ZnO‐NPs, no statistically significant toxic effects were observed. The antibacterial efficacy of ZnO‐NPs was assessed against Gram‐positive and Gram‐negative microorganisms. MC‐ZnO‐NPs exhibited a 67.9% inhibition zone against Escherichia coli at 0.04 mg L−1, while raw‐ZnO‐NPs exhibited 75.6% inhibition at the same concentration.CONCLUSIONThe study suggests that ZnO‐NPs synthesized from M. charantia exhibit both growth‐promoting effects on wheat without significant phytotoxicity and potent antibacterial properties, particularly against Escherichia coli. However, further investigations are warranted to comprehensively understand the interactions between ZnO‐NPs and plants. Future research should focus on M. charantia, exploring its enhanced effects on plant growth, development and antibacterial attributes. These findings hold promise for potential agricultural applications, emphasizing the need for detailed phytotoxicological assessments of ZnO‐NPs. © 2023 The Authors.

Biomimetic nanotechnology is a fast-growing technology with far-reaching implications in a variety of therapeutic applications. The goal of this research is to develop green, environmentally friendly, and cost-effective strategies for producing cobalt oxide (Co3O4) nanoparticles from Bos Taurus Indicus (A-2) urine and zinc oxide nanorods from the hydrothermal process. A solid-state reaction process is used to make nanocomposite materials. The synthesized nanomaterials and composites were characterized using advanced characterization techniques such as XRD, FE-SEM with EDS, DLS, Zeta potential, FT-IR, Raman spectroscopic analysis, and TGA with DSC analysis. The anti-bacterial, Anti-oxidant and anti-inflammatory effects of the synthesized nanomaterials and composites were investigated. This implies that they might be beneficial in medicine and drug administration.
