Reports summarize nanotechnology - nanoparticles research from Maringa State University

Published in Gene Therapy Weekly, December 23rd, 2010

2010 DEC 23 -- "Chemically synthesized magnetite and poly(thiophene)-coated magnetite nanoparticles and the correlations between their magnetic, structural, and microstructural properties are investigated. A typical superparamagnetic behavior was observed for faceted nanoparticle agglomerates of magnetite and nanocomposite," researchers in Maringa, Brazil report.

"In nanocomposites, the polymer layer causes a sharp decrease in the spin disorder, which reduces the anisotropy constant significantly. This happens because the intimate contact between magnetite and poly(thiophene) leads to charge transfer from the polymer to the core via polaron interactions,...
