Research in a Nugget


‌Brief description of research

Our research group aims at understanding the surface chemistry, spectroscopic and microscopic investigation of organic and biological supramolecular complexes. The chemistry of monolayers of supramolecular complexes is of paramount importance on account of many potential applications in diverse fields such as manufacture of new polymers, bio- and chemisensors, protective surface coatings, conductive films, optoelectronic devices, etc.

 

  • Specifically we are focusing on:
  • Combinatorial chemistry
  • Molecular recognition
  • Development of chemi- and biosensors
  • Tissue engineering
  • Aggregation studies regarding amyloidogenesis
