By a News Reporter-Staff News Editor at Clinical Trials Week -- Investigators publish new report on Apatites. According to news reporting originating from Bucharest, Romania, by NewsRx correspondents, research stated, "This paper presents a comparative study of antimicrobial and electrochemical performance of CoCrMo alloy surface treated with hydroxyapatite coating or silver nanoparticles (nAg) in the presence/absence of albumin addition. Nanoparticles dimension was quantified using dynamic light scattering."
Our news editors obtained a quote from the research from Polytechnic University, "Antibacterial activity was evaluated by a spread plate method, while electrochemical characterization of CoCrMo samples coated and uncoated was studied by open circuit potential and cyclic polarization experiments. Furthermore, all surface coatings characterization was investigated by transmission electron microscopy, scanning electron spectroscopy, and energy-dispersive x-ray spectroscopy. The highest corrosion rate in simulated body solution (SBF) is for untreated CoCrMo alloy, and the lowest value is for CoCrMo alloy treated with nAg after addition in SBF of 80 g/L albumin."
According to the news editors, the research concluded: "Only the surface treated with nAg has antibacterial effect."
