The main focus of this part of the research is the manipulation of microparticles. This includes active microrheology with optical tweezers that is used for studying biological samples.
In combination with varying external magnetic field, we study interactions between superparamagentic microparticles and formation of different stable mesophases, depending on the precessing magnetic field cone opening angle. Artificial swimmers were created and their motion observed in microfluidic channels. Thermal motion of particles is also studied, including fabrication of integrated microfluidic thermal pumps based on thermoviscous expansion and thermal tweezers, which can be used for single nanoparticle manipulation.
Microfluidic arrays are produced and used to study a variety of systems, including liquid crystals and biological samples.
