IBM scientists, based in Zurich, Switzerland, have developed a flexible microscopic probe made from silicon that will help researchers and pathologists take tissue samples for drug studies and disease diagnostics.
The probe is made up of a silicon microfluidic head with two microchannels. The head head re-aspirates the liquid that it injects into a patient preventing the spread and accumulation of the liquid on the surface, which can lead to overexposure.
Here's more from IBM's press release.
