Research Interests

Professor Rishpon¹s research is centered on the fundamentals of biological interactions at solid-liquid interfaces with emphasis on electrochemical biosensors.

 

Current research includes:

  • Novel immunosensors based on enzyme channeling.
  • Biosensors based on enzyme cascades.
  • Electrochemical and optical investigation of the electron transfer reactions of macrocyclic and polymeric mediators and application of their catalytic activity in biosensors.
  • NO sensors; Investigation of the action of the enzyme nitric oxide synthase; measurement of NO in cancer cells.
  • Electrochemical on-line monitoring of gene expression and its application in the detection of environmental pollutants.
  • Interactions of estrogen and xenoestrogen with their hormone-receptors in lipid layers.
  • Biosensors to identify infectious diseases.
  • Biosensors to detect environmental pollutants.
  • Biosensors to detect food safety.
  • Optical evanescent wave biosensors (in cooperation with the Faculty of Engineering).
  • Investigation of tuberculosis KatG peroxidase-catalase reaction and its role in the resistance to isoniazide, the current treatment of choice.
