“…Based on the results, the silver nanoparticles exhibited bactericidal effect on both the Gram-positive and Gram-negative strains, with the highest antibacterial activity toward BS and SA, and the lowest towards PA. Based on these results, the silver nanoparticles synthesized using M. communis L. leaf extract showed better or comparable antibacterial activity compared with other inorganic antibiotics. [45][46][47][48][49] Silver-containing nanomaterials can present antibacterial activity via several routes: (1) by attaching to the walls of the cell and entering inside the cells, 32 (2) by attaching to membrane proteins and respiratory chains of mitochondria, (3) by generating ROS 33 by catalyzing partial reduction reaction of oxygen, 34 (4) by releasing silver ions followed by protein binding (via thiol groups of protein) and inactivation and DNA binding (via phosphate groups of DNA), and (5) by altering bacterial structure, physiology, and metabolism. 35,36 To investigate the probable mechanism of the antibacterial activity of the nanoparticles, various experiments were carried out.…”

Silver nanoparticles have been synthesized using only Myrtus communis L. leaf extract by a facile procedure without other reagents. The extract played the roles of both reducing and capping agent. The nanoparticles were characterized using field-emission scanning microscopy, and remained stable for at least 3 weeks. Antibacterial activity of the nanoparticles was evaluated toward Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Enterococcus faecalis based on inhibition zone disk diffusion assays. The minimum inhibitory and bactericidal concentrations of the nanoparticles were obtained. Mechanisms for the antibacterial activity were proposed.

“…Antibacterial efficacy was done using the disk diffusion method. The efficacy of the Gram-negative bacteria was more as compared to the Grampositive bacteria [43]. Maaza et al studied an eco-friendly method for the synthesis of zinc oxide nanoparticles using leaf extract of Sageretia thea which act as a reducing as well as a stabilizing agent [44].…”

Green synthesis of metal oxide nanoparticles has been emerging highlight of the research owing to its unique properties that make them applicable in various fields of science and technology. The method of synthesis is simple, cost effective and environmental friendly. After review, we reported the phyto-synthesis of metal oxide nanoparticles using plant extract with an emphasis on recent developments. Biomolecules such as alkaloids, flavonoids, polyphenols etc. present in the plant extract can be used for the reduction of metal ions to nanoparticles in a single step process. These extract also act as a stabilizing agent. Although, a good number of work has been reported for the synthesis of gold and silver nanoparticles. However, limited no of work has been reported for the synthesis of copper, zinc and iron oxide nanoparticles. We have discussed the green synthesis of copper, zinc and iron oxide nanoparticles and potential of their antibacterial efficacy

“…The widespread use of antibiotics in foodstuff, animal husbandry and domestic cleaners led to the development of antibiotic resistant microbial strain (Chaisatit et al 2010). Many bacterial species like Salmonella, Escherichia coli, Staphylococcus aureus, Enterococcus and Pseudomonas species are highly resistant to the common antibiotics (Zare et al 2017). Thus, the presence of toxic organic dyes and MDR microbes are the most serious thread toward human health and aquatic life.…”

The tin dioxide nanoparticles (SnO 2 NPs) were fabricated via eco-friendly process using Daphne mucronata (D. mucronata) leaves extract as capping and reducing agent. The N 2 adsorption/ desorption experiment was performed to determine the surface area by Brunauer-Emmett-Teller (BET) method and S BET was found to be 147 m 2 g −1 . The crystalline nature and lattice parameter was studied by x-ray diffraction (XRD) and calculated crystallite size is 15.63 nm. The surface morphology was examined by scanning electron microscopy (SEM) and the estimated average particle size is 64 nm. The percentage composition and purity of the SnO 2 NPs was determined by energy dispersive x-ray (EDX). The raman active modes were identified by using raman spectroscopy while functional groups upon the surface were studied by using fourier transform infrared (FTIR) spectroscopy. The photocatalytic performance of SnO 2 NPs was examined against Rhodamine 6G (R6G) and 99.70% rhodamine 6G (R6G) were degraded in 390 min with the degradation rate of 0.0148 per min. The SnO 2 NPs were screened against the selected microorganisms and the order of antimicrobial activity is given as; Gram negative bacteria (GNB)>Gram positive bacteria (GPB)>fungi.
