聚多巴胺表面改性技术在分离科学领域中的应用

Applications of polydopamine surface modification technique in separation science

聚多巴胺作为新型仿生材料,具有制备过程简单、环保和适用面广(可用于各种类型基质表面改性)等优点,已被广泛应用于化学、生物医学、药学、传感器和电池制造等领域。在分离科学领域,聚多巴胺不仅可用于制备色谱固定相,也可用于制备新型的富集材料。该文对聚多巴胺的形成机理研究现状进行了简单介绍,主要综述了近年来聚多巴胺在色谱分离和富集领域的应用,包括毛细管电泳/电色谱、液相色谱、分子印迹固相萃取、分散固相微萃取和固相微萃取等技术领域。

As a novel bio-inspired material, polydopamine （PDA） coatings are easily formed inenvironmentally friendly conditions on virtually all kinds of inorganic and organic substrates.PDA has been applied in many areas such as chemical, biomedical, pharmaceutical, sensor andbattery manufacturing, etc. In the field of separation science, PDA can be used to prepare newenrichment materials, as well as stationary phases for chromatographic separation. In thisreview, the research status of the formation mechanism of PDA is introduced firstly; emphasesare put on the recent applications of PDA in the areas of separation and enrichment, such ascapillary electrophoresis, liquid chromatography, molecularly imprinted solid-phase extraction,dispersive solid-phase microextraction and solid phase microextraction, etc.
