Beyond Biopsy

First, Duke University researchers are working on an autonomous microbot that can perform biopsies without human assistance. Then, a University of Washington team is working on a technique that uses nano-particles to perform molecular level imaging from inside the body.

Next Gen Surgical Robots Could Steer Themselves – [dukenews.edu]

Feasibility studies conducted by Duke University bioengineers have demonstrated that a robot — without any human assistance — can locate a man-made, or phantom, lesion in simulated human organs, guide a device to the lesion and take multiple samples during a single session. The researchers believe that as the technology is further developed, autonomous robots could some day perform many more simple surgical tasks.

Multifunctional nanoparticle enables new type of biological imaging – [uwnews.org]

Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible.

UW researchers have developed a multifunctional nanoparticle that eliminates the background noise, enabling a more precise form of medical imaging — essentially erasing the haystack, so the needle shines through. A successful demonstration with photoacoustic imaging was reported today (July 27) in the journal Nature Communications.
