微流体技术在灵活性、透明度、功能性、耐磨性、规模缩小或复杂性增强方面的进步目前受到材料和组装方法选择的限制。有序微纤化是一种以超高分辨率将明确的孔隙光学打印到聚合物薄膜上的方法。在这里，我们演示了这种方法，通过几个简单的步骤，以多种灵活和透明的格式创建自封闭的微流体装置。结构颜色是有组织的微纤维化的一种特性，成为这些微流体装置的固有特征，从而实现了原位传感能力。由于系统流体动力学取决于内部孔径，因此毛细管流动以结构颜色为特征，同时与通道尺寸无关，无论设备是否以厘米或微米尺度打印。此外，产生和组合不同内部孔隙率的能力使 OM 微流体能够用于基于孔径的应用，正如生物分子混合物的分离所证明的那样。有组织的微纤化可用于以高分辨率将明确的孔隙度光学打印到聚合物薄膜中。在这里，作者使用这种方法在不同的柔性基板中创建自封闭的微流体装置，并利用结构颜色的内在外观进行传感应用
Advances in microfluidic technology towards flexibility, transparency, functionality, wearability, scale reduction or complexity enhancement are currently limited by choices in materials and assembly methods. Organized microfibrillation is a method for optically printing well-defined porosity into thin polymer films with ultrahigh resolution. Here we demonstrate this method to create self-enclosed microfluidic devices with a few simple steps, in a number of flexible and transparent formats. Structural colour, a property of organized microfibrillation, becomes an intrinsic feature of these microfluidic devices, enabling in-situ sensing capability. Since the system fluid dynamics are dependent on the internal pore size, capillary flow is shown to become characterized by structural colour, while independent of channel dimension, irrespective of whether devices are printed at the centimetre or micrometre scale. Moreover, the capability of generating and combining different internal porosities enables the OM microfluidics to be used for pore-size based applications, as demonstrated by separation of biomolecular mixtures. Organized microfibrillation can be used to optically printing well-defined porosity with high resolution into thin polymer films. Here, the authors use this method to create self-enclosed microfluidic devices in different flexible substrates and exploit the intrinsic appearance of structural colours for sensing application
