Chemical Gradients Formation for Directed Molecular Transport |
| 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. In this regard, reliable methods to form mili- to micron-scale chemical gradients are required. We present two examples of chemical gradient formation in different soft materials: polymer brush and hydrogel. We demonstrate molecular transport, concentration and separation driven by the formed chemical gradients in hydrogels. Such a new concept to control 2D transport of molecules could generally be applied for signal enhancement of chemical sensors. |
