Researchers create a new class of SOUND WAVE and say it could create inhalable 'supervaccines'

  • Hybrid blend, 'surface reflected bulk waves,' are both powerful and gentle
  • Team has already put them to use in a new highly efficient nebulizer device
  • System could be used for needle-free vaccines and inhalable medicine

 

Researchers have created an entirely new class of sound wave, a feat that hasn't been achieved in more than half a century.

The new method from RMIT University has already allowed the team to dramatically cut down on the time required for administering inhalable vaccines.

With further development, this new class of sound wave could be revolutionary in stem cell therapy, they say.

The new sound wave is a hybrid, created from two different types of sound waves called bulk waves and surface waves.

While bulk waves act as one vibrating entity, surface sound waves behave similar to rolling ocean waves.

The combined 'surface reflected bulk waves,' as the researchers have named them, are both powerful and gentle, making them useful for biomedical devices.

The team has already put them to use in a new nebulizer device, which delivers vaccines and medicine to the lungs.

'We have used the new sound waves to slash the time required for inhaling vaccines through the nebuliser device, from 30 minutes to as little as 30 seconds,' said Dr. Amgad Rezk, from RMIT's Micro/Nano Research Laboratory.

'But our work also opens up the possibility of using stem cells more efficiently for treating lung disease, enables us to nebulise stem cells straight into a specific site within the lung to repair damaged tissue.'

'This is a real game changer for stem cell treatment in the lungs.'

Stem cells are extremely fragile, but these sound waves could be used to manipulate the cells without causing damage.

The new device, called HYDRA, turns electricity into mechanical vibration, which then breaks liquid into vapour form.

'It's basically 'yelling' at the liquid so it vibrates, breaking it down into vapour,' said Rezk, who co-authored the study with PhD researcher James Tan.

'The combination of surface and bulk wave means they work in harmony and produce a much more powerful wave.'

'As a result, instead of administering or nebulising medicine at around 0.2ml per minute, we did up to 5ml per minute. That's a huge difference.'

The researchers are using HYDRA to make a new type of nebulizer, called Respite, which will be cheap and portable.

As development continues, this system could be used to deliver needle-free vaccines to infants, and administer inhalable medicines to asthma, cystic fibrosis, and diabetes patients.
