摘要： A supported nanofiber medium useful for segregating chemical species is provided by selecting a polymer, selecting a substrate; and electrospinning the polymer to form a nanofiber medium on the supporting substrate. When the substrate is a planar surface, the nanofiber medium will be a mat suitable for conducting chromatographic separation. When the substrate is a filament, the nanofiber medium is an annular mat suitable for solid phase microextraction. The nanofiber media formed may be selectively cross-linked and at least partially carbonized to carbon nanofibers. The nanofiber medium is supported on the substrate without the use of binder material.

摘要： Preparation of a molecularly imprinted carbon is described. The molecularly imprinted carbon has a surface that is imprinted on the molecular level for a specific template molecule of interest, making it highly selective for analytes corresponding to at least a portion of the template molecule. Devices including the molecularly imprinted carbon and their use in methods of detecting analytes are also described. As an example, dibutyl butylphosphonate (DBBP), a surrogate for chemical warfare agents, was used as a template molecule. Electrospun molecularly imprinted SU-8 and pyrolyzed polymer (PP) solid-phase microextraction (SPME) devices were prepared; their ability to preferentially extract DBBP from an aqueous matrix, with and without interferences present, was evaluated via comparison with non-imprinted SU-8 and PP SPME fibers. The electrospun devices demonstrated a higher selectivity for DBBP, as evidenced by their extraction time profiles. The MI-SPME fibers tested extracted at least 60% more DBBP than their non-imprinted counterparts.

摘要翻译：描述了分子印迹碳的制备。分子印迹的碳具有在特定的目标模板分子的分子水平上印上的表面，使其对应于至少部分模板分子的分析物具有高选择性。还描述了包括分子印迹碳的装置及其在检测分析物的方法中的用途。作为例子，使用了作为化学战剂的替代物的丁基膦酸二丁酯（DBBP）作为模板分子。制备了Electrospun分子印迹的SU-8和热解聚合物（PP）固相微萃取（SPME）装置; 通过与未印刷的SU-8和PP SPME纤维进行比较，评估了其具有和不存在干扰的水性基质优先提取DBBP的能力。电纺装置显示出对DBBP的较高选择性，如其提取时间曲线所证明的。所测试的MI-SPME纤维比其非印刷对象提取至少多60％的DBBP。
