BIO ORIENTED NANOPOROUS MATERIALS FOR PERM-SELECTIVE ION TRANSPORTATION

Abstract

Nanoporous structure has been actively applied for various application such as desalination, water purification. electro-chemical cell or bio applications. Recently, easy way to fabricate nanoporous membrane has been developed but it was still not applicable for bio applications because of bio-compatibility. Hydrogel was one of the known material for bio-compatible membrane, but it was hard to control. In this work, we found several candidates for bio degradable nanoporous membrane in the living organism, human nail, hen egg yolk, and albumen. The nanofluidic functionality was verified by ion concentration polarization phenomena. Surface charge of each material was estimated by conductance profile.
