Title: Derivatization of Plastic Microfluidic Devices With Polyelectrolyte Multilayers
Published: May 01, 2000
Abstract: Microchannels fabricated in plastic materials by room temperature imprinting demonstrate large variability in surface charge as a result of the fabrication procedure. Surface charged groups are primarily localized on the channel walls and not on the channel floor resulting in differences in adsorption properties in the channel. Polyelectrolyte multilayers can be used to effectively coat the plastic microchannel surface with high reproduciblity and excellent stability. We show that polyelectrolyte multilayers can be used to alter both direction and rate of flow in plastic microchannel devices.
