Extracellular directed ag NPs formation and investigation of their antimicrobial and cytotoxic properties.

The use of microbial cell culture a valuable tool for the biosynthesis of nanoparticles is considered a green technology as it is eco-friendly, inexpensive and simple. Here, the synthesis of nanosilver particle (AgNP) from the yeast, , gram (+), and gram (-), was shown. In this field we are the first to study their the antimicrobial effects of the microorganisms mentioned above against pathogens and anticancer activity on MCF-7 cell line.

Formation of Matricaria chamomilla extract-incorporated Ag nanoparticles and size-dependent enhanced antimicrobial property.

Various concentrations of Matricaria chamomilla (M. chamomilla) flower extract was used for biosynthesis of Ag NPs with different sizes, 70±5 (Ag NP-1), 52±5 (Ag NP-1) and 37±4nm (Ag NP-3), and size-specific antimicrobial activity of them was evaluated towards Gram+ Staphylococcus aureus (S. aureus), Gram- Escherichia coli (E.

The Effect of Pelargonium endlicherianum Fenzl. root extracts on formation of nanoparticles and their antimicrobial activities.

Herein, we report the biosynthesis of Ag NPs, for the first time, using identified antimicrobial molecules (gallic acid+apocynin) and (gallic acid+apocynin+quercetin) from the medicinal plant Pelargonium endlicherianum Fenzl. and dramatically enhanced antimicrobial activity. We also investigate the role of each molecule on formation Ag NPs and explain the increase in the antimicrobial activity of identified molecules mediated Ag NPs.
