Abstract
Recent studies have established EVQ-218 as a novel type of allotrope silver nanoparticle (AgNP). The patented laser-based method of manufacture imparts EVQ-218 with unique surface properties that enhance particle stability without capping agents and other stabilizing chemistry. In this study, EVQ-218 was screened against RAW 264.7 murine macrophages, MH-S murine alveolar macrophages, and THP-1 human monocyte cell lines. IC50 values were obtained, and cellular uptake and phagocytosis assays were conducted. Results of this study indicate that the intracellular uptake of EVQ-218 did not make any apparent physiologically significant change in cell morphology and phagocytic activity of macrophages at nontoxic doses.
期刊介绍:
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
