Thanks to new microfluidics and nanotechnology, cancer doctors may be able to design custom therapies for patients by analyzing just a teaspoon of their blood. Researchers from Massachusetts General Hospital’s Center for Engineering Medicine and its Cancer Center have now shown that they can capture the rare cancer cells shed by tumors into the bloodstream using a new high-tech chip the size of a credit card. Counting and analyzing these wandering tumor cells could mean better early cancer detection and an improved method for monitoring whether treatments are working.
