New Anions Study Findings Reported from C. Bergmann and Co-Authors

June 6, 2014

By a News Reporter-Staff News Editor at Health & Medicine Week -- New research on Anions is the subject of a report. According to news reporting from Hannover, Germany, by NewsRx journalists, research stated, "Calcium phosphates, functionalized with nano-sized metal particles, are a promising material class for the treatment of bone defects. However, a sintering process is required in principle to achieve sufficient strength of calcium phosphate scaffolds."

The news correspondents obtained a quote from the research, "In this work laser-generated nano-sized silver, gold and platinum particles were adsorbed on micro-sized beta-tricalcium phosphate particles and further heat treated at temperatures between 600 and 1200 degrees C. Gold and platinum nanoparticles underwent exponential growth starting at about 600 degrees C, while sintering of beta-tricalcium phosphate started at 800 degrees C. We hypothesise that this phenomenon is caused by a heat-induced evaporation and growth process where the decrease of the particle number is directly correlated with the size increase. The silver nanoparticles on the other hand formed a new phase with the calcium phosphate (AgCa10(PO4)(7)) during the heat treatments and could not be observed within the ceramic scaffold anymore."

According to the news reporters, the research concluded: "Addressing the lack of information in nanoparticle-combined calcium phosphate scaffolds, this study contributes to the further modification of bone replacement materials with biologically relevant functions and molecules."
