This microhole chip identifies and sorts cancer cells

Fraunhofer researchers have created a microhole chip that can identify and characterize cancer cells within minutes – helping to catch metastasis before it can begin.

Traditional fluorescence-activated cell sorting (FACS) gives an estimate of the number of tumor cells in a patient’s bloodstream. If there is a higher concentration of tumor cells, there is a greater chance that they will increase metastasis. However, FACS is limited to a small set of colored dyes that can be used.
