“…The biogenic synthesis of CuO and ZnO nanoparticles was confirmed by X-ray diffraction (XRD) analysis ( Figure 1 ), TEM image ( Figure 2 ), energy dispersive X-Ray spectroscopy ( Figure 3 ), and FTIR analysis ( Figure 4 ). The XRD peaks observed for the lyophilized nanoparticle samples in Figure 1 a correspond to (111), (000), (200), (−112), (−202), (020), (202), (−113), (022), and (220) planes confirming the presence of copper oxide [ 48 ], while the 2θ values of 31.94, 34.64.36.42, 47.83,56.85,62.93, and 68.2 (100, 002, 101, 102, 110, and 103,112) observed in Figure 1 b can be attributed to the zinc oxide diffraction [ 32 ].…”

The biogenic synthesis of CuO and ZnO nanoparticles (NPs) was carried out by Stenotrophomonas maltophilia. The shape, size, and chemical identity of the CuO and ZnO NPs were determined using FTIR, XRD, SEM, EDX, and TEM analysis. The study aimed to investigate the effects of the CuO and ZnO NPs on Amaranthus hybridus seed germination and plant growth. Two different fertilizer application modes (hydroponics and foliar) were studied with varying concentrations of CuO (0.06 µM, 0.12 µM) and ZnO (0.12 µM, 0.24 µM) nanoparticles with water control and Hoagland’s media control. The hydroponic system of fertilizer application demonstrated better efficiency in terms of plant growth as compared to the foliar application. The agronomic traits, SPAD value, total reducing sugars, antioxidant activity, amount of copper, and zinc ions in root and shoot were analyzed for all experimental plants and found better with the nanoparticle application. The highlight of the study is the application of extremely low concentrations of CuO and ZnO nanoparticles, almost 70% lower than the copper and zinc salts in the Hoagland’s medium for improved plant growth. The use of lower concentrations of nanoparticles can prevent their accumulation in the environment and also lower the production cost. The high antioxidant concentration exhibited by the plants treated with CuO and ZnO nanoparticles ensures the enhanced plant’s resistance to infections and pests while promoting plant growth.
