Abstract
The work done during the past decade in order to adapt molecularly imprinted polymers (MIPs) to the capillary format and subsequently use these highly selective matrices for capillary electrochromatography (CEC) are reviewed in this article. MIPs are prepared utilizing a templated polymer synthesis where the template addresses the selectivity of the resulting polymer. These polymers possess binding characteristics that are comparable to the biological antibodies. Due to the polyclonality of the binding sites in the MIP, the separation result in severe peak broadening and tailing when performed in the isocratic mode. This was seen early in the development of MIPs as selective stationary phases in liquid chromatography (LC). As a mean of... (More)
The work done during the past decade in order to adapt molecularly imprinted polymers (MIPs) to the capillary format and subsequently use these highly selective matrices for capillary electrochromatography (CEC) are reviewed in this article. MIPs are prepared utilizing a templated polymer synthesis where the template addresses the selectivity of the resulting polymer. These polymers possess binding characteristics that are comparable to the biological antibodies. Due to the polyclonality of the binding sites in the MIP, the separation result in severe peak broadening and tailing when performed in the isocratic mode. This was seen early in the development of MIPs as selective stationary phases in liquid chromatography (LC). As a mean of decreasing these problems, much effort was put into adapting the MIP to fit in CEC systems, that offers an efficiency that is superior to that in LC. Aiming to increase the efficiency of the MIP-CEC systems, different MIP formats have been developed that can be divided into three conceptually different categories, i.e., the monolithic, the microparticle and the coating. The strive for MIP formats that can be used in small bore capillaries has led to the development of MIP formats applicable to miniaturized systems approaching the chip format. Although prepared in order to perform MIP-CEC mediated separations, these formats can be used in a broad range of applications were the characteristics of the MIP, e.g. stability, selectivity and cost efficiency, could offer an interesting solution to cover the needs.
