Rust makes nanocapsules open by remote control

  January 19/26, 2009
Mix the right two plastics with a sprinkling of rust and you can deliver drugs by turning on a magnetic field.

The polymers and iron oxide nanoparticles self-assemble into nanocapsules that can carry drugs. A magnetic field heats the nanoparticles and therefore the nanocapsules. At 40 degrees Celsius the nanocapsules contract, which squeezes out the contents within a few minutes.

The nanocapsules could be used to delivers drugs that are released by remote control.
