Nanotechnological filters could lead to wearable or implantable artificial kidneys, experts told UPI's Nano World. Animal studies for artificial-kidney prototypes should begin one or two years from now, and clinical trials would follow a year or two afterward, reported scientists at Biophiltre in Burlingame, Calif., the medical-device company developing the artificial-kidney technology. Nearly 900,000 patients worldwide suffering from kidney disease require dialysis, a medical procedure mimicking the kidney's normal function of filtering waste from the blood. "About 21 percent of patients on dialysis on any year die," nephrologist Allen Nissenson, director of the University of California at Los Angeles...
