Sangeeta, Bhatia, MD, PhD, of the Massachusetts Institute of Technology in Cambridge, is developing a method of CRC screening using nanoparticle delivery and a urine test. Through modification, yogurt bacteria produce nanoparticles that interact with colorectal tumors after being consumed. The interaction can then be detected by a simple urine test.

The test has been demonstrated in mice, but further clinical trials in both mice and humans are still necessary, according to the report.
