Popis: Current approaches for treating patients with end stage renal disease include hemodialysis and peritoneal dialysis, both of which are diffusion-based treatments that require a dialysate solution. The native kidney has separate filtration (glomerulus) and transport (nephron) capabilities. Although artificial methods for simulating glomerular function using membrane ultrafiltration have been proposed, there are no known technologies for simulating the ion transport functions of the nephron. Here we have created a synthetic nephron using activated wafer electrodeionization (AWEDI). AWEDI incorporates mesh electrodes within an electrodeionization wafer, allowing ion selectivity and transport rate to be modulated independently. We demonstrate the capabilities of AWEDI with several physiologically relevant ions which mimic the fine control of ion transport by the kidney. Furthermore, by integrating our AWEDI technology with ultrafiltration, nanofiltration, and reverse osmosis modules, the possibility of incorporating AWEDI technology in an artificial kidney is demonstrated. The nephrons in the kidney transport ions and organic molecules, but may not work effectively in patients with kidney disease. Here, a synthetic nephron is created, based on activated wafer electrodeionization, and shown to enable the transport of several physiologically relevant ions.
