Focused ultrasound combined with microbubbles is increasingly being used to safely and reversibly open the blood-brain barrier (BBB) for the treatment of brain tumors and neurodegenerative disorders.

Researchers have developed a bubble microrobot capable of being guided around the tiny complex blood vessels of the brain using ultrasound. Successfully tested in mice, the ‘microvehicle’ holds ...

While it might sound like a weapon of oceanic destruction in the hands of Aquaman’s arch enemies, the new “stingraybot” from a team at ETH Zurich (the Federal Institute of Technology of Switzerland) ...

A team of researchers from Caltech and the University of Southern California has developed a microrobot for drug delivery ...

In most cases, the targeted microbubble contrast agents (MCAs) are fitted with a high-affinity targeting ligand. After the MCAs are adhered to the target, they begin to improve the acoustic signal ...

Encapsulated microbubbles (EMBs), tiny gas-filled bubbles coated in lipid or protein shells, play a central role in biomedical ultrasound. When exposed to ultrasound waves, EMBs contract, resulting in ...

ETH Zurich researchers have investigated how tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny liquid jets ...

Using "microbubbles" and ultrasound can mean more targeted breast biopsies for patients with early breast cancer, helping to determine treatment and possibly saving those patients from undergoing a ...

Injecting trillions of microscopic bubbles into severely injured people may help keep them alive until arrival at a hospital for treatment. The technique, which essentially creates a “third lung,” ...
