Research topics

Electrochemical biosensors for food and healthcare analysis

Arrays of nanoelectrodes (NEAs) are characterized by high signal/noise ratios, improved detection limits, enhanced mass transport, high miniaturization. These properties are exploited for the development of innovative electrochemical affinity sensors in which a  biorecognition layer is immobilized on the surface of the NEA. On the basis of this approach, we have developed different biosensors aimed at detecting:

  1. DNA hybridization;
  2. antigens and antibodies

As far as topics 1 is concerned, the study is finalized to the genotyping of human papilloma virus.

For  topics 2, we are developing  electrochemical immunosensors for the receptor HER2 (breast cancer therapy), anti-tissue transglutaminase (diagnosis of celiac disease), gliadin (gluten-free foods), immunoglobulin IgY  (formulations containing chicken egg yolk). 


Cultural heritage diagnostics and conservation

The preservation of works of art requires the knowledge of the nature of the materials that constitute such works. The decision of a conservation treatment is connected to the conditions, materials and procedures to be used at each operation. The combination of different instrumental analytical techniques is able to provide an insight into the issues that confront the conservator. In our laboratory we exploit electrochemical, SEM-EDS, colorimetric techniques to the identification of pigments, colorants and binders present in artworks such as frescoes, stained glass, photography, icons.
