Design, fabrication and application of a microfluidic nanofiltration module for separation and purification of macromolecules and nanoparticles

Creator:: Rundel, Jack T.
Abstract:: A microfluidic nanofiltration module has been designed, fabricated and applied to the continuous-flow, pressure-driven, post-synthetic purification of macromolecules and nanoparticles via diafiltration using a commercially available organic solvent resistant nanofiltration membrane, STARMEM 122. This module will readily interface with other microscale components within a "nanofactory" for the rapid synthesis, purification...
