In this study, zinc oxide nanoparticles (ZnO NPs) were synthesized using an aqueous extract of the Ocimum lamifolium (O. lamifolium) plant. The I-optimal coordinate exchange randomized response surface methodology (RSM) was used to optimize the effect of the zinc acetate precursor, temperature, and time on ZnO NPs by designing nine runs. From ANOVA analysis, the significance and validity of the designed model showed that the optimal values of the zinc acetate precursor, temperature, and time during ZnO NPs synthesis were found to be ∼0.06 M, ∼30 °C, and ∼1.35 h, respectively. The obtained ZnO NPs under these optimized conditions were characterized and explored by UV–vis, TGA/DTA, FTIR, XRD, SEM-EDX, TEM, HRTEM, and SAED. Furthermore, the electrocatalytic performance of ZnO NPs was performed for sulfamethoxazole (SMZ) sensing activity with a 0.3528 μM (S/N = 3) limit of detection (LOD). In addition, an antibacterial study revealed that ZnO NPs confirmed an excellent zone of inhibition against E. coli, S. aureus, P. aeruginosa, and S. pyogen pathogenic drug resistance bacterial strains at concentrations of 50, 75, and 100 μg/mL. Thus, ZnO NPs synthesized using the O. lamifolium leaf have a potential electrocatalytic activity for diverse organic pollutant detection as well as a desirable material for such drug resistance antimicrobial strains.

Zinc oxide nanoparticles (ZnO NPs) were prepared by co‐precipitation of zinc acetate with Ampelocissus martini rhizome extract (AM). Four conformations of ZnO NPs were obtained by conjoined precipitation of sodium hydroxide, zinc acetate dihydrate, and AM: ZnO NPs‐01, ZnO NPs‐02, ZnO NPs‐03, and ZnO NPs‐04. The structure of ZnO NPs was confirmed by X‐Ray diffraction (XRD). Fourier transform infrared (FTIR) analysis was conducted to identify functional groups. The formation and morphology of the synthesized ZnO NPs were confirmed by field emission scanning electron microscopy (FE‐SEM) with Energy dispersive X‐ray spectroscopy (EDS) mapping, and transmission electron microscopy (TEM). Free radical scavenging activity was determined by 2,2‐diphenyl‐1‐picryl‐hydazyl‐hydrate (DPPH) and 2,2/‐azino‐bis‐(3‐ethylbenzothi‐azoline‐6‐sulfonic acid (ABTS) assays. Antibacterial activity was examined by disc diffusion analysis together with minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). ZnO NPs‐04 showed the highest inhibition in DPPH and ABTS assays and was active against E. coli and S. aureus with MICs=10 mg/mL and 5 mg/mL, respectively. These findings indicated that synthesized NPs could be utilized for several medicinal applications.

“…Besides these, green synthesis technique [13] has drawn much interest in the contemporary research of synthesis of NPs and is becoming increasingly important focus in materials' research in the age of environment-friendly development. Green synthesis of wurtzite type ZnO NPs using extracts of plant parts like leaf, ower, fruit and root has been reported in many studies where the particle size is signi cantly varied based on the nature of the plant extract used, such as, Acanthus sennii (19-24 nm) [14], Centella asiatica (11 nm) [15], Plumeria (27 nm) [16], Cassia auriculatacan (24-30 nm) [17], Raphanus sativus var. Longipinnatus (66 nm) [18], Olea europaea (40-124 nm ) [19], Deverra tortuosa (9-31 nm) [20], Mangifera indica (23 ± 9 nm) [21], Annona muricata (17 ± 4 nm) [21], Laurus nobilis L.

We report the results obtained on the studies made for temperature and frequency dependence of the dielectric constant, loss and ac conductivity for pristine and green-synthesized ZnO nanoparticles as well as investigations of their electric modulus. Frequency-dependent dielectric studies are carried out with the pelletized samples of ZnO at different temperatures. At lower frequencies (< 1 kHz) and at higher temperatures the ZnO nanoparticles have giant dielectric constant values (~ 4x104), and such a temperature-dependent giant dielectric constant has not been seen earlier, to our knowledge, in any pristine ZnO nanoparticle. In the lower frequency region and below 100○C the nature of temperature dependence of the dielectric constant for pristine ZnO is in contrast with that observed for the green-synthesized ZnO nanoparticles. This anomalous temperature dependence of dielectric constant may be correlated with combined effect of the in-plane and out of plane thermal-expansion coefficients of ZnO. A temperature-dependent poly-dispersive relaxation mechanism in these materials have been observed. The electrical conduction mechanism is found to be significantly modulated by the use of the extract. Electric modulus study reveals that the electrical conduction and dielectric polarization follow the same mechanism in these ZnO nanoparticles. The dependences of the dielectric constant, dielectric loss, conductivity and polarization mechanisms observed in the synthesized ZnO nanoparticles are envisaged as the signatures of the effective control of the flour extract on the crystal growth and formation of grain boundaries. A plausible growth mechanism of the ZnO nanoparticles in presence of the flower extract containing phytochemicals is also provided.
