General Microfluidic Methods for Formation of Micron-Scale Chemical Gradients in Polymer Brushes |
| 초록 |
Surfaces containing defined microscale chemical gradients are important for various applications including a sample library with an extremely dense variable set and a smart platform to direct molecular transport. Formation of microscale chemical gradients in soft-matter surfaces remains challenging. We present two facile microfluidic methods to form narrow surface chemical gradients in a tertiary amine functionalized polymer brush via a selective quaternization. Two methods are on the basis of different physical mechanisms, permeation into porous media vs. diffusion at laminar interface, respectively. |
