A Review on Green Synthesis and Applications of Iron Oxide Nanoparticles.

Bio-fabrication of iron oxide nanoparticles by using different sources of plants, plant parts and microbial cells have become a great topic of interest nowadays due to its eco-friendly nature. The stabilizing and capping agents in biological sources are biocompatible, stable and non-toxic which make its use beneficial for various biomedical applications. The bacteria are able to utilize metal ions and convert them into their respective nanoparticles by secreting different biomolecules.

Non-antibacterial as well as non-anticancer activity of flower extract and its biogenous silver nanoparticles.

Silver nanoparticles were synthesized by using the white flower extract of Albizia lebbeck as a source of reducing and capping agents. A. lebbeck white flower extract and silver nanoparticles were checked for their antibacterial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa and Ba cillus subtilis by using Mueller Hinton agar, nutrient agar and Luria Bertani agar using the well diffusion method.

Effect of Nutrient Media on Antibacterial Activity of Silver Nanoparticles Synthesized Using .

Silver nanoparticles synthesized using leaf and fruit extracts which were centrifuged at different speeds (rev/min) were screened for anti-bacterial activity by using four human pathogens namely , (Gram negative) and , (Gram positive). The silver nanoparticles showed good anti-bacterial activity against gram-positive as well as gram-negative bacteria. Nonetheless, silver nanoparticles synthesized using leaf extract has shown pre-dominant anti-bacterial activity rather than fruit extract.
