The Biomechanisms of Metal and Metal-Oxide Nanoparticles

Nanoparticles (NPs) are defined as having at least one dimension measuring 100 nanometers or less [1]. NPs modulate a wide range of biological reactions, including inflammation, cell toxicity, and genotoxicity [2,3]. Since nanomaterials can bind to a wide variety of substances, including proteins,

New Protein-Coated Silver Nanoparticles: Characterization

Jan 07, 2021 makes it hard to determine their safe use [7,8]. Specifically, silver nanoparticles (AgNPs) are among the most studied and applied nanomaterials in the biomedical field [9]. The benefit and toxic effects of silver nanoparticles have been related to their physicochemical properties such as their size, shape, coating, and zeta potential [10].

Antibacterial activity of SPIONs versus ferrous and ferric

These nanoparticles (NPs) can bind to bacterial membranes via hydrophobic or electrostatic interactions and pass through cell barriers. In this study, the authors evaluated the antibacterial activity of magnetic NPs in comparison with ferrous and ferric ions.

Poly (ε-caprolactone) microspheres for prolonged release of

genotoxicity were evaluated on HepG2 cell line. The interaction of PCL/SeNPs with phagocytic cell line (Raw 264.7 macrophages) was monitored as well. It was found that the microspheres in investigated concentration range had no acute cytotoxic effects. Finally, SeNPs, as well as PCL/SeNPs, showed a

context silver nanoparticles (AgNPs) synthesized from plant extracts have attracted attention. However, it is necessary to know the mechanisms of response of the microorganism to the action of plant extract and silver nanoparticles [YAN LI et al., 2017]. Objective: evaluate Spondias tuberosa extract and AgNPs activity
