The preparation and characterization of electrosynthesized poly(o-phenylenediamine) (PPD) imprinted by glucose (iPPD) is reported as the first case of an electrosynthesized polymer molecularly imprinted by a neutral template. The material is employed as the recognition element of a QCM biomimetic sensor for glucose. Scatchard analysis of the relevant calibration curve offers information on the equilibrium and binding sites involved in glucose detection. XPS comparison of PPD and iPPD supports the occurrence of a templating effect. On this basis, molecular imprinting electropolymerization is proposed as a possible strategy for the preparation of new materials with molecular recognition properties to be applied in biomimetic sensors.

The material is employed as the recognition element of a QCM biomimetic sensor for glucose. Scatchard analysis of the relevant calibration curve offers information on the equilibrium and binding sites involved in glucose detection. XPS comparison of PPD and iPPD supports the occurrence of a templating effect. On this basis, molecular imprinting electropolymerization is proposed as a possible strategy for the preparation of new materials with molecular recognition properties to be applied in biomimetic sensors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
