“…A broad peak of lower intensity at 627.9 cm −1 can be attributed to B 2 g phonon modes. The results are in good agreement with those of reported literature, which indicates that the as prepared product consists of single-phase CuO with a monoclinic structure [14,15].…”

“…1a). The UV-visible spectral analysis displayed a surface Plasmon peak around 270 nm and 670 nm, which indicates the emergence of CuO nano materials, which is similar to previous reports [9,[14][15][16][17][18]. The incidence of the SPR absorption reflects the shape and size of the nano materials.…”

“…Recently, the extract of Aloe Vera plant has been successfully used to synthesize monoclinic phase with average particle size of 20 nm spherical nanoparticles with high yield by the reaction of aqueous metal source ions with the extract of the Aloe Vera plant [13]. Though there are few reports on CuO nano particles using plant extracts [9,[14][15][16][17][18], to the best of our knowledge, there is no report on synthesis of CuO rod like nanomaterials using A. racemosus root extract. It is well known that nano structured materials have enhanced antibacterial activity due to their high surface area.…”

The present investigation aims to synthesize copper oxide nano rods using Asparagus racemosus roots extract (Ar-CuO) in an ecofriendly process. The synthesized CuO nano rods are characterized by XRD, SEM, TEM, FT-IR, Raman and UV-visible spectroscopy. X-ray diffraction pattern showed typical monoclinic structure. SEM and TEM analysis revealed the formation of self-assembled CuO nano rods with diameter and length ~ 50-100 nm and 400-500 nm respectively. The antimicrobial activity of green synthesized copper oxide nanorods was tested against various bacterial pathogens i.e., E. coli, B. subtilus, K. pneumonia, A. hydrophila, P. fluorescens, Y. ruckeri, F. branchiophilum and E. tarda with fascinating action towards harmful bacteria.

“…Several approaches for CuO synthesis and surface modification have been proposed through utilizing various parts of plants such as leaves, fruit, and flowers [21][22][23][24]. Several microorganisms, plants, and plant extracts have been extensively used to synthesize CuO nanoparticles (Table 1) to avoid the consumption of toxic chemicals [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. The O. sanctum (Tulsi) is supposed to contain oleanolic acid, rosmarinic acid, eugenol, carvacrol, Linalool, β-caryophyllene, and ursolic acid [39][40][41][42].…”

HIGHLIGHTS• Eugenol (4-allyl-2-methoxyphenol) extracted from O. sanctum leaves is used as a natural reducing agent for the synthesis of CuO nanoflowers (NFs).• CuO-NFs can degrade methylene blue with an efficiency of 90%. • CuO-NFs offer a new vision to deactivate multi-drug microorganisms. A B S T R AC T C o pper oxide nanoflowers (CuO-NFs) have been synthesized through a novel green route using Tulsi leaves-extracted eugenol (4-allyl-2-methoxyphenol) as reducing agent. Characterizations results reveal the growth of crystalline singlephase CuO-NFs with monoclinic structure. The prepared CuO-NFs can effectively degrade methylene blue with 90% efficiency. They also show strong barrier against E. coli (27 ± 2 mm) at the concentration of 100 µg mL −1 , while at the concentration of 25 µg mL −1 weak barrier has been found against all examined bacterial organisms. The results provide important evidence that CuO-NFs have sustainable performance in methylene blue degradation as well as bacterial organisms.

In recent years, the biosynthesized of metallic nanoparticles has been rapidly growing due to their environmentally synthesis and widespread applications in science and industry. In this study, we have reported the green synthesis of NiONPs using an aqueous extract of Trigonella subenervis (NiONPs@TS). The nanoparticles were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopy (EDS). To find various applications for NiONPs@TS, the nanoparticles (NPs) were used as a catalyst for synthesizing some benzimidazole derivatives. The electrochemical behavior and antibacterial activity of NiONPs@TS were also evaluated. FE-SEM images exhibited a uniform spherical morphology in size of 28.21 nm for the biosynthesized nanoparticles. According to the XRD analysis, 26.43 nm was measured for NiONPs@TS crystal size. Benzimidazole derivatives were synthesized using NiONPs@TS as the catalyst with a yield of 69-92%. NiONPs@TS showed a significant electrocatalytic activity to glucose oxidation. The linear response range and detection limit were found to be 10-200 and 3.2 μM, respectively. Furthermore, NiONPs@TS exhibited an acceptable antibacterial activity in various assays, including well diffusion, disk diffusion, minimum inhibition concentration (MIC), and minimum bactericidal concentration (MBC). The best antibacterial activity was obtained against Bacillus subtilis with MIC of 4.0 ± 0.0 μg/ml and MBC of 6.7 ± 2.3 μg/ml. The obtained results showed the ability of NiONPs@TS in different fields such as catalytic, electrochemical sensing, and antibacterial activity, which can be contributed to the presence of biomolecules in T. subenervis extract.
