HEALTH: Ultrasound pulses could replace daily injections for diabetics

"Once the ultrasound is turned off, the nano-network re-forms and more insulin leaks out to form another reservoir. In tests on diabetic lab mice, one injection of the nanoparticles was enough to regulate blood glucose levels for as much as 10 days. When a nano-network is depleted, another batch of particles can be injected – the old network will be absorbed by the body within a few weeks.
The scientists are now working towards applying the technology to humans. Dr. Zhen Gu is leading the research, which was recently described in a paper published in the journal Advanced Healthcare Materials." Gizmag.
