    Nanoparticles take a fantastic, Magnetic Voyage

    April 28, 2019, Categories  Chemistry/Nanotechnology


    MIT engineers have designed a magnetic microrobot that can help push drug-delivery particles into tumor tissue (left). They also employed swarms of naturally magnetic bacteria to achieve the same effect (right).

    Tiny robots powered by magnetic fields could help drug-delivery nanoparticles reach their disease targets. MIT Engineers have designed tiny robots that can help drug-delivery nanoparticles push their way out of the bloodstream and into a tumor or another disease site. The magnetic microrobots could help to overcome one of the biggest obstacles to delivering drugs with nanoparticles: getting them to exit blood vessels and accumulate in the right place.

    An artist's representation of the nanoparticle removal chip developed by researchers in Professor Michael Heller's lab at the UC San Diego Jacobs School of Engineering. An oscillating electric field (purple arcs) separates drug-delivery nanoparticles (yellow spheres) from blood (red spheres) and pulls them towards rings surrounding the chip's electrodes. The image is featured as the inside cover of the Oct. 14 issue of the journal Small. Credit: Stuart Ibsen and Steven Ibsen.
