Micro-fluidic devices usually deal with sophisticated nanostructures but it is more important that they require high level control over surface properties for their performance. In this paper, we studied microfluidic device modification utilizing polymer thin film coating. In particular, weak polyelectrolytes were used for the surface wettability control, chemical functionality and patterning. With the polymer coating, aqueous analyte solution was successfully delivered into micro-channel without external pressurized devices. In addition to that, surface-functioanlized nonoparticles were combined to the system, which may be useful in delivery and/or detection for biosensors. |
