Ultrasound Drug Delivery System Shows Promise in Early Tests
Scientists are working on a new way to deliver medicine using sound waves.
They're using tiny packages called nanoparticles to carry drugs.
These packages are designed to be opened by ultrasound, which is like a very focused sound.
The scientists put a little bit of sugar in the packages to make them work better and stay stable.
When they aim the ultrasound at a specific part of the body, the packages open up and release the medicine only where it's needed.
This could make drugs safer and more effective, as it reduces the amount of medicine that affects the rest of the body.
The research showed promising results in rats, delivering drugs to the brain and limbs.
This technology could help treat conditions like depression by targeting specific areas while avoiding unwanted side effects.
US researchers are developing a non-invasive ultrasound system for targeted drug delivery.
The system uses nanoparticles to encapsulate drugs and ultrasound to release them.
A 5% sucrose solution within the nanoparticles enhances stability and ultrasound responsiveness.
The system was tested in rats, delivering ketamine to specific brain regions and painkillers to limbs.
The technology aims to maximize therapeutic effects and minimize side effects.
