Overview on Research

My current research is focused on formation of microgels with vast morphological features including:

  • Formation of anisotropic and multicompartment microgels e.g. Janus particles (JPs) and Complex colloidal particle clusters (CCPCs) in flow
  • Formation of microgels conjugated with enzymes and affibodies for biomedical purposes
  • Utilization of microgels as anti-ice surface coatings – reduction of the ice crystals adhesion and ice recrystallization inhibition

Research focus

  • Polymer synthesis: photoemulsion polymerization, ATRP, RAFT
  • Microgel formation: flow chemistry
  • Interaction between multivalent polyelectrolytes and proteins: ITC, QCM-D

Projects
