Imaging the brain with ultrasound waves

Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences in the Earth's interior, ...

Acoustic propulsion of nanomachines depends on their orientation

Microscopically tiny nanomachines which move like submarines with their own propulsion—for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, ...

The sound of light: Photoacoustics for biomedical applications

Medical imaging techniques provide a unique view inside the body and are invaluable for diagnosis and disease monitoring. From X-ray, over MRI to ultrasound, the field is vast and diverse. When imaging biological tissue, ...

'Seeing' single cells with sound

If you are a researcher who wants to see how just a few cells in an organism are behaving, it is no simple task. The human body contains approximately 37 trillion cells; the fruit fly flitting around the overripe bananas ...

Opto-mechanical non-reciprocity in fiber

The internet era that we live in depends completely on the transfer of vast amounts of information over optical fibers. Optical fibers are literally everywhere. In fact, the overall length of optical fibers installed on our ...
