Determining Effective Magnetic Moment of Multicore Nanoparticles

Most commercial nanoparticles do not possess a single magnetic core but have small magnetic crystals called crystallites. The important question is how these crystallites behave inside a multicore nanoparticle and how they respond to an applied magnetic field. In the Journal of Applied Physics, researchers compare the effective magnetic moments of different multicore nanoparticle systems and shows that they are magnetic-field dependent. The paper’s findings are important for researchers optimizing magnetic nanoparticles for various applications.

Nanosize Device ‘Uncloaks’ Cancer Cells in Mice And Reveals Them to The Immune System

Scientists at Johns Hopkins report they have designed and successfully tested an experimental, super small package able to deliver molecular signals that tag implanted human cancer cells in mice and make them visible for destruction by the animals’ immune systems. The new method was developed, say the researchers, to deliver an immune system “uncloaking” device directly to cancer cells.
