New electrochemical sensor platforms for analytical probes

Challenge

Development of electrochemical sensors for sensing applications in foods, health and environment.

Solution

To develop electrochemical sensors based on nanostructured modified electrodes with immobilisation of highly-specific recognition elements for sensing and diagnostic applications in foods, health and environment.

Objectives, Activities and Results expected / achieved

Expected Goals:
• Development of electrochemical sensors based on modified nanostructured electrodes with improved analytical performance, testing the platforms with important analytes in food, health and the environment.

Objectives Achieved:

• Sensory platforms developed on nanomaterial-modified carbon electrodes, characterized by electrochemical and impedance techniques and surface analysis;

• Electroactive redox phenazine polymers formed on the surface of carbon electrodes by electropolymerization;

• Immobilization of enzyme recognition elements on the modified electrodes, e.g. poly(neutral red) films in which the enzyme pyruvate oxidase was immobilized and used for the determination of pyruvate in food and phosphate in water;

• Detection of trace metal ions in environmental samples after preconcentration on printed electrodes protected by phenazine polymer films;

• Very successful application to important food, health and environmental analytes.
