Capillaries of many dimensions are fabricated and modified, for use across a wide range of applications within analytical science. This extends from sample preparation and sample extraction, to separation sciences, and detection sciences. Photonic crystal fibres, emerged in the 1990’s, and were specifically designed for optical applications, predominantly as waveguides. Since then, a range of modifications have been reported, with the fibres applied to a wide variety of analytical applications, in liquid and gas phase analyses or detection. This review aims to provide an overview of photonic crystal fibres and related multi-channel capillaries, the chemical modifications that have been carried out, and the subsequent applications of the developed materials towards analytical separations, including sample preparation.

可以制造和修改许多尺寸的毛细管，以用于分析科学中的广泛应用。这从样品制备和样品提取到分离科学和检测科学。光子晶体光纤出现在1990年代，是专门为光学应用而设计的，主要是作为波导。从那时起，已经报道了一系列的修改，这些纤维被应用于液相和气相分析或检测中的各种分析应用中。这篇综述旨在概述光子晶体光纤和相关的多通道毛细管，已进行的化学修饰以及已开发材料在分析分离（包括样品制备）中的后续应用。
