How to pop open soft nanoparticles using sound waves

Ultrasound has long been an important tool for medical imaging. Recently, medical researchers have demonstrated that focused ultrasound waves can also improve the delivery of therapeutic agents such as drugs and genetic material. ...

A new method for precision drug delivery: painting

If traditional drug delivery were a type of painting, it might be akin to paintball. With good aim, a majority of the paint ends on the bullseye, but it also drips and splashes, carrying streams of paint across the target.

Ultrasound imaging needle to transform heart surgery

Heart tissue can be imaged in real-time during keyhole procedures using a new optical ultrasound needle developed by researchers at UCL and Queen Mary University of London (QMUL).

Neutrophil-inspired propulsion

Inspired by white blood cells rolling on endovascular walls before transmigrating to the disease site, scientists at ETH Zurich have succeeded in getting particles to move along the walls of microscopic, three-dimensional ...

Why do some head knocks cause more damage than others?

Veteran sailors know that rogue waves can rise suddenly in mid-ocean to capsize even the largest vessels. Now it appears that a similar phenomenon called shear shock wave occurs in the concussed brain. It may help explain ...

New ultrasound techniques for peering inside bony structures

Ultrasound—sound with frequencies higher than those audible to humans—is commonly used in diagnostic imaging of the body's soft tissues, including muscles, joints, tendons and internal organs. A technology called high-intensity ...
