Silica films in optical and electrochemical sensors

Research Fields:

Previous and Current Research

Main field of research: synthesis and application in chemical analysis of hybrid silica-organic polymer films modified with analytical reagents or biomolecules. Optical and electrochemical sensors.

Other fields: bioanalytical chemistry, nanochemistry, environmental and food analysis, sol- gel synthesis, spectroscopic and voltammetric methods of analysis.

Luminescent and electrocatalytic properties of metal, metal oxide and carbon based nanoparticles immobilized onto the surface of silica. The development of sensitive elements of optical and electrochemical sensors based on silica films modified with nanoparticles and analytical reagents, enzymes or antibodies. Application of the developed sensors for the environmental, biological, pharmaceutical and food analysis.

Future Projects and Goals

The development of multi sensing platforms based on the planar electrodes array modified with composite film: nanoparticles – silica- biomolecules.

Methodological and Technical Expertise

  • Sol- gel synthesis of mesostructured organo-mineral films based on modified silica
  • Development of sensitive elements of optical and amperometric chemical and bio sensors
  • Investigation and application in analysis of metal, metal oxide and carbon based nanoparticles
  • Modification and application in analysis of screen-printed electrodes.
  • Spectroscopic and electrochemical methods of analysis

Our group is focused on the development of new sensing materials based on silica film coatings contained immobilized analytical reagents or bio ligands (enzymes or antibodies). We study complex formation, redox and catalytic properties of the composite SiO2 coatings. Application of the developed materials for the analysis of inorganic and organic compounds in the environment, food, biological, pharmaceutical and cosmetic products.
