This review is mostly focused on the recently emerged methodologies for preparing the appropriate extracting media with enhanced capacity, stability and selectivity, which could be used in capillary microextraction (CME). We particularly consider conductive polymers, sol-gel-based materials, monolithic coatings, molecularly-imprinted polymers and xerogels. Moreover, we discuss recent advances in configuration of CME, array capillaries and unbreakable substrates.
