A new material can filter nanometer-sized molecules at 10 to 100 times the rate of commercial membranes

Dialysis, in the most general sense, is the process by which molecules filter out of one solution, by diffusing through a membrane, into a more dilute solution. Outside of hemodialysis, which removes waste from blood, scientists use dialysis to purify drugs, remove residue from chemical solutions, and isolate molecules for medical diagnosis, typically by allowing Read more about A new material can filter nanometer-sized molecules at 10 to 100 times the rate of commercial membranes[…]
