21. Separation and Metrology of Nanoparticles by Nanofluidic Size Exclusion
Samuel M Stavis, Jon C Geist, Michael Gaitan
A nanofluidic approach to the separation and metrology of nanoparticles is demonstrated. Advantages of this approach include nanometer-scale resolution, nanometer-scale to submicrometer-scale range, mitigation of hydrodynamic and diffusional limitat ...
22. Solution and Surface Composition Gradients via Microfluidic Confinement: Fabrication of a Statistical-Copolymer-Brush Composition Gradient
Chang Xu, Susan E. Barnes, Tao Wu, Daniel A Fischer, Dean M DeLongchamp, J Batteas, Kathryn L Beers
A simple method to generate solution gradients through microfluidic confinement is described. The solution gradient inside a microchannel was formed by varying the relative infusion rates of two solutions that differed in compositions. The establishm ...
23. Theoretical Analysis of a Magnetophoresis-Diffusion T-Sensor Immunoassay
Thomas P Forbes, Matthew S Munson, Samuel P Forry
Microfluidic immunoassays have demonstrated broad application to the detection and quantification of analytes ranging from small drug molecules to large proteins and biomolecules. These systems exhibit short length scales, reduced sample volumes, and ...
