Current Research Interest

  • Synthetic organic chemistry for the development of the haptens, antigens and immunogens necessary for specific antibody production.
  • Development of new improved immunoassay techniques for easy and sensitive mycotoxin monitoring in foods under field condition.
  • Development of novel immunoassays for small molecules in non-competitive format.
  • Development of antibody-based analytical methods for monitoring of environmental pollution and clinical diagnostics.
