New Findings from McGill University in the Area of Nanoparticles Reported

June 27, 2014



By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Nanoparticles are presented in a new report. According to news originating from Montreal, Canada, by NewsRx correspondents, research stated, "A mathematical model for electrophoresis of polyelectrolyte coated nanoparticles (soft spheres) in polyelectrolyte hydrogels is proposed, and evaluated by comparison to literature models for bare-sphere gel electrophoresis and free-solution electrophoresis. The utilities of approximations based on the bare-particle electrophoretic mobility, free-solution mobility, and electroosmotic flow in hydrogels are explored."

Our news journalists obtained a quote from the research from McGill University, "Noteworthy are the influences of the particle-core dielectric constant and overlap of the polyelectrolyte shell. The present theory, which neglects ion-concentration and charge-density perturbations, indicates that the gel electrophoretic mobilities of metallic-core nanoparticles in polyelectrolyte gels can be qualitatively different than for their non-metallic counterparts."

According to the news editors, the research concluded: "These insights will be beneficial for interpreting nanoparticle gel-electrophoresis data, optimizing electrophoretic separations, and engineering nanoparticles for technological applications."
