Silver nanoparticles (AgNPs), owing to their unique physical and chemical properties, have become increasingly popular in consumer products. However, data on their potential biological effects on marine organisms, especially invertebrates, remain very limited. This proof of principle study reports the chronic sub-lethal toxicity of two coated AgNPs (oleic acid coated AgNPs and polyvinylpyrrolid...

Teucrioside, 9′-decarboxyrosmarinic acid 4′-O-α-rhamnosyl-(1‴→6‴)-O-β-galactosyl-(1‴→4″)-Oα-rhamnoside is a natural phenolic compound. It has been isolated and identified from the genus Teucrium. Teucrium widely used in traditional medicine for its antioxidant, diuretic, antiulcer, antitumor, anti-inflammatory, antispasmodic antibacterial properties. Since silver nanoparticles have superior phy...

The present work shows the implementation of response surface methodology, fed by an experimental central composite design (CCD) to find conditions that allow maximizing inhibition microorganism Staphylococcus aureus with nanoparticles TiO2 silanized 3-aminopropyltriethoxysilane (APTES) and doped Ag. In addition, poly(lactic) acid composites were prepared these Ag/TiO2 aim confer their antimicr...

a-Silica encapsulated silver nanowires (diameter of 25 +/- 5 nm, average length of 10 mum) have been synthesized by reacting (Me3Si)4Si with AgNO3 in nearly quantitative yield. Formation of the a-silica shell layer (1-3 nm) in situ appears to be one of the most important factors in this simple process.

Structural phase transition in AgN03 at high temperature is simulated by molecular dynamics. The simulations are based on the potentials calculated from the Gordon-Kim modified electron-gas formalism extended to molecular ionic crystals. AgN03 transforms into rhombohedral structure at high temperature and the phase transition is associated with the rotations of the N03 ions and displacements of...

AgNO3-impregnated prep-TLC purification of the wax extract of Cocos nucifera allowed the isolation and identification of skimmiwallinin as an additional skimmiwallinol derivative from the cuticular wax of coconut palms. Identification was based on the comparison of its spectroscopic data with those reported in the literature.

In order to fabricate antimicrobial carboxymethyl chitosan-nanosilver (CMC-Ag) hybrids with controlled silver release, this study demonstrated comparable formation via three synthetic protocols: 1) carboxymethyl chitosan (CMC) and glucose (adding glucose after AgNO3), 2) CMC and glucose (adding glucose before AgNO3), and 3) CMC only. Under principles of green chemistry, the synthesis was conduc...
