Active Matter and Fluids Research


 My research is about the light-matter interaction of micro and nano systems. I study how light can be used to activate inert materials such as colloids to induce their self-propulsion, self-assembly into larger superstructures and how to gain optimal  control over them. This is a highly interdisciplinary field involving photonics, materials science and biomimetics.

In particular my research involves:
  • nano and micro machines
  • self-assembled active matter
  • microcavities and small forces
This addresses current scientific and technological challenges in developing novel methods, for example, in smart drug delivery systems, automated search-and-rescue missions, and soil and water remediation from environmental pollutants. Moreover, the study of small forces in micro cavities allows to understand and build a new generation of sensors whose enhanced sensitivity enables the detection of transient effects and molecules.

About Me:

Dr. Falko Schmidt has defended his doctoral thesis in 2021 from the physics department at the University of Gothenburg in Sweden. He is currently a PostDoctoral researcher at the Friedrich Schiller University in Jena, Germany working on nanophotonics systems such as single photon emitters in 2D materials.
He has over 7 years of experience in building holographic optical setups for experiments on the optical manipulation of micro- and nanosystems. He is the author of 6 scientific peer-reviewed articles published in renowned journals (e.g. Nature Communications, Physical Review Letters). He is also the co-founder of Lucero AB, a spin-off from research at the University of Gothenburg developing automated manipulation solutions for single cells in drug screening purposes.
