A Sign of Hope to Renal Disease Patients
HKUST students propose renal disease treatment alternative that will be affordable for all

Late stage renal disease is debilitating. When their kidneys stop functioning, patients are treated through dialysis that have serious physical side effects and are costly for many. But change may soon be coming—a team of HKUST students has invented a solution that uses graphene to reduce dialysis treatment time and costs, and enhance its effectiveness. The team’s idea is simple yet previously untested. Dialysis usually filters out all blood impurities, but surface-modified graphene can trap targeted impurities, ensuring that vital salt and glucose are retained. As a result, life expectancy for patients should go up, and treatment time would also be greatly reduced. The team’s leader, Tim Tian, a... Read More
