Interaction of ancillary ligand with fluorescent metal complexes within the MIP

7 Interaction of ancillary ligand with fluorescent metal complexes within the MIP 

The fluorescence of the DVMB-Eu complex within the MIP is significantly altered in the presence of PMP. The sharp 610 nm peak, present in the spectrum of the original polymer-bound DVMB-Eu -PMP complex and absent in the spectrum of the empty polymer, is restored upon exposure of the polymer to 1 M NaOH solutions containing PMP. While a benchtop model of the sensor was more 

A number of commonly occurring pesticides and herbicides was also examined and found to cause no interference, even at extremely high concentrations. Such sensors, which combine the selectivity of MIPs with the extremely sensitive fluorescence properties of lanthanide complexes, ensure that this will be a very fruitful area of research. 

8 Determination of ftuorophores using MIPs formed on quartz crystals 

Polymers imprinted against the sodium salts of anthraquinone 2-sulphonic acid and pyrene sulphonic acid both showed a 3- to 4-fold higher sensitivity to pyrene than to anthracene.
