| Outline of Final Research Achievements |
Patients suffering from kidney diseases need to visit hospitals for hemodialysis treatment 3 times a week, which deteriorates their quality of life. Wearable or implantable micro hemodialysis systems would not only improve the QoL but also alleviate the damage onto the patients health due to its rather slow dialysis treatment (24 hours x 7 days). Such hemodialysis devices, however, need to overcome the biofouling originating from the blood.
In this work, we attempted to modify the surface property of the dialysis membrane while maintaining the diffusion capacity by depositing nano-porous thin films. Parylene and fluorinated diamond like carbon were tested. First we developed the deposition processes of the nanoporous films and then, experimentally verified the effectiveness of the surface modification using whole cow blood. 28-days-long experiments showed successful reduction of adhesion of biomaterials by the surface modification.
