Imagine a dialysis machine small enough that a patient could wear it. A super-thin filtering material may allow researchers at the University of Rochester to revolutionize dialysis for patients with kidney disease. Jim McGrath, an associate professor of biomedical engineering at the University of Rochester, says the thinner the membrane that blood passes through, the more efficient its filtering capacity.

McGrath says the material they're working with filters blood more efficiently, and could end up in a much smaller device that could fit on an arm band. We can basically replace the experience of going to a dialysis center three times a week with nightly dialysis at home with a device that's about the size of a cell phone and achieve the same sort of clearance level. This is actually like a clinic on a chip, he said.
