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. ...

Ultrasound aligns living cells in bioprinted tissues

North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the biofabrication process.

Compact fiber laser may enable wearable tech and better endoscopes

By creating a new twist on fiber optic sensors, researchers in China have developed a smart, flexible photoacoustic imaging technique that may have potential applications in wearable devices, instrumentation and medical diagnostics.

New imaging technique peers inside living cells

To undergo high-resolution imaging, cells often must be sliced and diced, dehydrated, painted with toxic stains, or embedded in resin. For cells, the result is certain death.

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 ...
