Imaging of Electro-Osmotic Flow in Plastic Microchannels

June 1, 2001

Author(s)

David J. Ross, T J. Johnson, Laurie E. Locascio

Wetting of Methanol on the n-Alkanes: Observation of Short-Range Critical Wetting

February 8, 2001

Author(s)

David J. Ross, D Bonn, J Meunier

We present results of the wetting properties of methanol at the liquid-vapor interface of different n-alkanes ranging from hexane to undecane. Measurement of the contact angle shows that, as the bulk critical point is approached, wetting transitions occur

Fabrication, Derivatization and Applications of Plastic Microfluidic Devices

February 1, 2001

Author(s)

S L. Barker, Michael J. Tarlov, David J. Ross, T J. Johnson, E A. Waddell, Laurie E. Locascio

Control of the polymer surface chemistry is a crucial aspect of development of plastic microfluidic devices. When commercially available plastic substrates are used to fabricate microchannels, differences in the electroosmotic flow mobility (EOF) from

Control of Flow Direction in Microfluidic Devices with Polyelectrolyte Multilayers

December 1, 2000

Author(s)

S L. Barker, David J. Ross, Michael J. Tarlov, Michael Gaitan, Laurie E. Locascio

Electroosmotic flow (EOF) is commonly utilized in microfluidics. Because the direction of the EOF can be determined by the substrate surface charge, control of the surface chemical state offers the potential, in addition to voltage control, to direct the
