Scientists Edge Closer to Probe that Would Inspect Atherosclerotic Plaques by Forcing Molecules to Sound Their Presence

Skoltech researchers and their colleagues have come one step closer to a working optoacoustic endoscopic probe — a device that could slip inside a blood vessel and analyze atherosclerotic plaques by shining laser light on them to make them wobble like a loudspeaker membrane and betray their chemical composition with an ultrasound signature.
