Abstract

We demonstrate a facile method for fabricating novel 3D microfluidic channels by using two-photon-activated chemistry to locally switch the interior surface of a porous host from a hydrophobic state to a hydrophilic state. The 3D structures can be infilled selectively with water and/or hydrophobic oil with a minimum feature size of only a few micrometers. We envision that this approach may enable the fabrication of complex microfluidic structures that cannot be easily formed via current technologies.

摘要

我们展示了一种简便的方法，通过使用双光子活化化学将多孔主体的内表面从疏水状态局部切换为亲水状态，来制造新型三维微流体通道。这些三维结构可以选择性地填充水和/或疏水性油，最小特征尺寸仅为几微米。我们设想，这种方法可能使制造目前技术难以轻易形成的复杂微流体结构成为可能。
