Bioreduction mechanism of silver nanoparticles

Materials Science and Engineering: C, 2020
The studies represent in-depth investigations of bacteria mediated reduction mechanism of silver nanoparticles (Ag NPs) not reported so far. Ag NPs were successfully synthesized by Bacillus subtilis spizizenni (NCIM 2063), and their bioreduction mechanism has been explored in detail.

Orthopedic Applications of Silver and Silver Nanoparticles

2017
Silver (Ag) has been known for its antimicrobial properties for centuries but has received renewed interest in recent years primarily due to the rise of antibiotic-resistance and the development of Ag nanoparticles (AgNPs). In orthopedics, multiple applications containing Ag are being developed including Ag dressings, Ag-coated prosthetic implants, and

Surface-independent antibacterial coating using silver nanoparticle-generating engineered mussel glue.

ACS Applied Materials and Interfaces, 2014
During implant surgeries, antibacterial agents are needed to prevent bacterial infections, which can cause the formation of biofilms between implanted materials and tissue. Mussel adhesive proteins (MAPs) derived from marine mussels are bioadhesives that

Silver nanoparticle decorated reduced graphene oxide (rGO) nanosheet: a platform for SERS based low-level detection of uranyl ion.

ACS Applied Materials and Interfaces, 2013
Herein, a simple wet-chemical pathway has been demonstrated for the synthesis of silver nanoparticle conjugated reduced graphene oxide nanosheets where dimethylformamide (DMF) is judiciously employed as an efficient reducing agent.

Biosynthesis of Silver Nanoparticles

MRS Proceedings, 2003
AbstractThe use of biomolecules in the creation of inorganic materials offers an alternative to conventional synthetic methods. Biomolecules are currently used to control nucleation and growth of inorganic nanoparticles. Here we demonstrate the formation of silver nanoparticles in the presence of silver-binding peptides.

Dithiocarbamate-Capped Silver Nanoparticles

The Journal of Physical Chemistry B, 2006
Nanometer-sized silver particles were synthesized by using didecylamine dithiocarbamates as the protecting ligands. With control of the initial ligand-metal feed ratios, the core diameter of the resulting particles was found to vary from about 5 to 2.5 nm, as determined by transmission electron microscopic measurements.

Green synthesis of silk fibroin-silver nanoparticle composites with effective antibacterial and biofilm-disrupting properties.

Biomacromolecules, 2013
Natural polymer Bombyx mori silk fibroin is used as a biotemplate to produce silver nanoparticles in situ under light (both incandescent light and sunlight) at room temperature.

Antiangiogenic properties of silver nanoparticles

Biomaterials, 2009
Angiogenesis is an important phenomenon involved in normal growth and wound healing processes. An imbalance of the growth factors involved in this process, however, causes the acceleration of several diseases including malignant, ocular, and inflammatory diseases.
