Finding new sound waves accelerates the treatment of lung and diabetes diseases more than 60 times

A new type of sound wave that has just been successfully developed for the first time in 50 years has revolutionized the use of stem cells in the treatment of disease.

Created by RMIT University audio experts in Melbourne, Australia, these sound waves - known as "surface reflectance wave waves" - are gentle enough to work on stem cells. without causing harm, which was previously impossible for sound waves.

Researchers have also used this technology to significantly improve the performance of a state-of-the-art vaporization device developed by RMIT, which helps deliver drugs directly into the lungs.

"We use this type of sound wave to shorten the time needed to inhale the vaccine through the inhaler, from 30 minutes down to just 30 seconds," said the co-founder of this study Dr. Amgad Rezk, from the Department. Research Micro / Nano at RMIT.

"Not only that, our research also opens up the potential of using stem cells more effectively when treating lung diseases , making it possible for us to straighten stem cells to a certain location. "In the lungs to treat damaged tissues. This is really a change in the face of lung treatment with stem cells ."

Surface reflected wave mass is the type of synthetic wave of two types of mass waves and surface waves.

Block waves make the whole material affect the entire vibration, an effect like you hold one end of a towel and shake it. In contrast, surface waves only vibrate the surface of affected material, just like ocean waves.

By combining two types of waves, the researchers created a kind of sound wave with more power than the two separate waves.

"The combination of mass wave and surface wave means that they operate in a certain rhythm and produce more powerful waves," Rezk said.

"Because of that, instead of measuring and smashing the medicine with a dosage of 0.2ml per minute, we can now use up to 5ml per minute. That's a huge difference."

Professor Leslie Yeo, RMIT, ran a trial of Respite, which was upgraded by this research.

Researchers have created a device to bring surface wave reflections to medical devices with a very loud name of Hydra .

This device transmits electricity through a piezoelectric chip, transforming them into mechanical vibrations, or sound waves, turning the solution into a mist that can be inhaled.

"It can be said that it is like" shouting "into a solution of shields to make them vibrate, breaking the structure and making them into a mist," Rezk explained.

Hydra was used to upgrade RMIT's pulse machine, with Respite, with the ability to put an extremely rich amount of medicine into the body without needing to drink or inject.

For patients with asthma or cystic fibrosis, this device may include an extremely high dose of high-dose medication, and it may also be used in delivering insulin to diabetics, and to administer vaccines to children without injection.
