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.
