This open tubular approach was improved by Tan and Remcho [21] who generated molecularly imprinted polymer films attached to walls of 25 pm ID capillaries. They injected as well a mixture of porogen, template, functional monomers, crosslinker, and initiator into a capillary activated with a polymerizable silane and performed the polymerization at elevated temperatures. A capillary with a total length of 100 cm and a separation length of 85 cm, respectively, coated with a polymer imprinted with dansyl-L-phenylalanine was applied for a separation of the racemate of dansyl-phenylalanine. Using acetonitrile/lOmmol (pH 7.0) phosphate buffer (10 1, v/v), a baseline separation of the two enantiomers could be achieved (Fig. 9).

A fluorescent sensor for dansyl-phenylalanine (dansyl-Phe-OFl) (Fig. 2, 1) has been successfully constructed by using methacrylic acid (MAA) and 2-vinyl-pyridine (2VPy) as the functional monomers and ethylene glycol dimethacrylate (EDMA) as the cross-linker. The fluorescence of the imprinted polymers upon analyte binding was detected using fiber optics, and the signal was found to be a function of the analyte concentration. The sensor also showed a moderate degree...

Chemiluminescent reactions have been used for signal generation both in flow injection systems and in separation techniques such as HPLC or CE, often in combination with chiral analysis. Detection by chemiluminescence of enantioselective capture of fluorescent analytes such as dansyl-phenylalanine by molecularly imprinted polymers was also reported [150]. Electrochemiluminescence (ECL) is...
