A shoebox-sized flow cytometer can count circulating tumor cells about 20 times faster than current devices, and with no professional training.
Developed by a team from Fruanhofer University, the cytometer automatically adds antibody-loaded dye to the cells before they move through a passage specially designed to have the cells flow through one at a time. As the cells travel in an orderly fashion through the passage, a laser light shines on them and counts them as they move by.
The narrow passage is key to the design, ensuring that no cell is overlooked. Because a 10mm sample of blood can hold around one billion suspended objects (a severely sick patient may have only five circulating tumor cells), detecting every cell is vitally important.
