Timo Laaksonen


Description of research and teaching

My research interests cover a wide area ranging from biomaterials and nanoparticles (drug/metallic) to drug release and release modeling.

Recently I’ve been most interested in

  • Controlling the adhesion, permeation and drug release from drug nanoparticles and drug loaded matrices.
  • Utilization of nanofibrillar cellulose in drug release applications.
  • Release modelling from drug (nano)formulations.

I'm always available for contacts on new projects related to the topics above. And why not on any other interesting ideas that you may have.
