  • Title: Electrocatalytical properties of polymethylferrocenyl dendrimers and their applications in biosensing.
    Author: Armada MP, Losada J, Zamora M, Alonso B, Cuadrado I, Casado CM.
    Journal: Bioelectrochemistry; 2006 Sep; 69(1):65-73. PubMed ID: 16443400.
    Abstract:
    The electrochemical characterization of polymethylferrocenyl dendrimers deposited onto a platinum electrode and their applications as hydrogen peroxide and glucose sensor are described. The redox dendrimers consist of flexible poly(propileneimine) dendrimer cores functionalised with octamethylferrocenyl units. Amperometric biosensors for glucose were prepared by immobilization of glucose oxidase onto these modified electrodes. The influence of the dendrimer generation and the thickness of the dendrimer layer, the effect of the substrate concentration, and the interferences and reproducibility on the response of the sensors were investigated.
