ABSTRACT
A molecularly imprinted two-dimensional photonic crystal hydrogel sensor was developed with erythromycin as imprinted molecule, polystyrene two-dimensional photonic crystal as templates, methanol as solvent, methacrylic acid as monomers and ethylene glycol dimethylacrylate as cross-linkers.The imprinted molecule was removed by methanol/acetic acid (9∶1, V/V).The results showed that the diameter of Debye ring increased 6 mm when the concentration of EM changed from 0 to 1×10-6 mol/L.Namely the lattice spacing decreased 30 nm.In addition, the diameter of Debye ring only increased 1.5 and 2.0 mm when the hydrogel immersed in 1×10-6 mol/L roxithromycin (RM) or erythromycin ethylsuccinate (EEs) solution.The result indicated that the sensor had high selectivity and could be used in determination of erythromycin with low cost and easy operation.
