Russian scientists have found that coating magnetic
nanoparticles with a non-magnetic silica shell coating
significantly decreased the viability of cancer cells in a low
frequency alternating magnetic field. The coating increases
nanoparticles stability, preventing aggregation in endosomes and
keeping them as effective magneto-mechanical actuators in a
low-frequency alternating magnetic field. The study was published
in Colloids and Surfaces B: Biointerfaces.
