Multilayer Low Tg Inorganic Glass/Polymer Barrier Films

Vennerberg D., Bemis Company, Inc., US

Conventional high barrier films are produced by coating or laminating inorganic materials to polymeric substrates. While successful at lowering the permeability of the films, several unit operations are required to introduce multiple inorganic barrier layers. [...]

Vapor-assisted bonding of poly(dimethylsiloxane) and silicon-based substrates

Sofla A.Y.N., Martin C., University of Toronto, CA

We present a novel method to reliably bond PDMS to glass, Si, SiO2 and PDMS. In this vapor-assisted method the surface of the PDMS is first brought into contact with the substrate. The PDMS-substrate structure [...]

How to SPION Glass Transitions

Concha M., DeLong S., Radu L., Kumar C., Bidwell-Hanson P., University of New Orleans, US

The magnetic properties of superparamagnetic iron oxide nanoparticles (SPIONs) have made them useful tools in a variety of applications ranging from drug delivery to magnetorheologic valving in microfluidic systems. The structure of SPIONs is typically [...]

Fabrication and Application in Microfluidics of Novel Transparent Preceramic Polymer Derived Glass Microcannels and Substrates

Kim D-P, Park J.H., Perumal J., Chungnam National University, KR

Generally, glass-based microfluidics with the chemical inertness and thermal stability have widely used, while plastics including PDMS have showed their convenience in fabricating microfluidic devices. Therefore, one can simply anticipate that it must be desirable [...]

The Bonding Technology for Microchannels with Electrode Patterns on the Glass Substrates

Parng S.H., Yang H.J., Shia T.K., Microsystem Technology Common Laboratory, TW

Objectives: Bonding surface preparation, process conditions, and integrated on-chip metal sheet resistance variation during bonding process were investigated in this work. Methods: We flatten the surface of the etched micro-channels with a fresh solution of [...]

Modular Design Approaches for MicroFluidic Systems

Gilde M.J., van den Vlekkert H., Leeuwis H., Prak A., CapiliX BV, NL

The possibilities promised by microfluidic systems have not only interested scientists, but also industries, especially in the areas of the Life Sciences (food, medical, biotech) and fine chemistry (pharma) [2]. Microfluidics is the MEMS-field in [...]
