Accounting for biological aggregation in heating and imaging of magnetic nanoparticles

September 2, 2014 12:09 pm | by EurekAlert! | News | Comments

Biological aggregation is a critical, yet often overlooked factor in the medical application of nanoparticles. Here we systematically characterize the effects of aggregation on both radiofrequency heating and magnetic resonance image (MRI) contrast of magnetic iron oxide nanoparticles (IONPs), including detailed analysis of the aggregate morphologies based on quasi-fractal descriptions....
