Scientists at Nanyang Technological University (NTU Singapore) have invented a new way to deliver cancer drugs deep into tumour cells.

The NTU scientists create micro-sized gas bubbles coated with cancer drug particles and iron oxide nanoparticles, and then use magnets to direct these bubbles to gather around a specific tumour.

Ultrasound is then used to vibrate the microbubbles, providing the energy to direct the drug particles into a targeted area.

This innovative technique was developed by a multidisciplinary team of scientists, led by Asst Prof Xu Chenjiefrom the School of Chemical and Biomedical Engineering and Assoc Prof Claus-Dieter Ohl from the School of Physical and Mathematical Sciences.

NTU's microbubbles were successfully tested in mice and the study has been published by the Nature Publishing Group in Asia Materials, the top journal for materials sciences in the Asia-Pacific region.
