Abstract
The green-synthesized method is rapid, superficial, toxic free, suitable, less time consuming, environmental safe and can be applied in a variety of applications in medicinal field. In the present study demonstrated antibacterial action of Vinca rosea Leaf extract medicated Silver Nanoparticles (VrL-AgNPs) tested against both Gram positive and Gram negative pathogens such as Staphylococcus aureus, Escherchia coli and Pseudomonas aeruginosa. The obtained results indicate the VrL-AgNPs achieved maximum zone of inhibition against test pathogens P. aeruginosa and significant action against E.coli and S. aureus. These green routes synthesized silver nanoparticles using biological sources like plant and plant extract which makes them a potent source of antibacterial agent.
Highlights
Nanotechnology is fast growing by producing nanoproducts and nanoparticles that can have novel and size-associated physico-chemical properties differing considerably from larger matter
Green route synthesized Vinca rosea Leaf (VrL)-AgNPs were tested for antibacterial activity by standard disc diffusion method against three different human pathogenic bacteria
Antibacterial activity of green route synthesized VrLAgNPs was evaluated by using standard Zone of Inhibition (ZOI) microbiology assay
Summary
Nanotechnology is fast growing by producing nanoproducts and nanoparticles that can have novel and size-associated physico-chemical properties differing considerably from larger matter. The advances in the field of nanosciences and nanotechnology has brought to fore the nanosized inorganic and organic particles which are finding increasing applications as amendments in industrial, medicine and therapeutics, synthetic textiles and food packaging products (Gajjar et al, 2009; Silvestre et al, 2011). This is present study deals with antibacterial properties Vinca rosea Leaf (VrL) extract medicated Silver Nanoparticles (VrL-AgNPs) using Vinca rosea plant extract tested against both Gram positive and Gram negative pathogens
