The rapidly developing field of contrast-enhanced ultrasound relies on the detection of gas-filled, encapsulated microbubbles that produce a unique signature in an acoustic field. These microbubbles ...

Cancer treatment has undergone a revolution in recent years, with many innovative therapies coming onto the market. This is particularly true for cancer therapies that use a person’s immune system to ...

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 ...

Microbubbles are small, gas-filled bubbles, typically between 0.5µm and 10µm in diameter, that are widely used as contrast agents in medical imaging and as carriers ...

Researchers have investigated how microbubbles tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets ...

Ultrasound images showing oxygen-loaded microbubbles entering the brain of a mouse. Left: contrast-mode image showing microbubbles entering the brain at the periphery (arrows). Right: greyscale image ...

Ultrasound-powered stingraybot A bioinspired soft surgical robot with artificial muscles made from microbubble arrays swims forward under swept-frequency ultrasound excitation. Right panels: motion of ...

For example, by combining the microbubbles with an antibody probe engineered to seek out biomarkers associated with cancer, doctors could target and then destroy tumors deep inside the body or detect ...

Researchers have designed process that uses ultrasound to modify the behavior of cancer-fighting T cells by increasing their cell permeability. They targeted freshly isolated human immune cells with ...

ETH Zurich researchers show how under ultrasound, microbubbles gas-filled bubbles generate liquid jets that penetrate cell membrane like tiny pinpricks. The dynamics of jets is governed by a ...
