Biological Physics Lab

Research group

Short description

The Biological Physics Lab is an interdisciplinary research group focusing on single-cell analysis and biomimetics. Our tool-box encompasses optical methodologies, such as fluorescence- and superresolution microscopy for visualisation, as well as optical tweezers for material and cell manipulation using laser light. Also, we develop and use miniature fluidic channels (microfluidics) for controlling the environment around the studied sample, or, to mimic organ miniature structures (organ-on-chip). The image analyses rely on AI-supported networks and numerical signal analysis, but also traditional biochemical and cell functionality tests are used. Ongoing projects regards cellular communication and physiological organ function to delineate the mechanisms behind the liver response to novel drug candidates in healthy and diseased tissue.

The two-layered chip design, in which the hepatocytes form liver tissue in hexagonal chambers (green), allows for diffusion-based perfusion of fresh cell media (red) continuously and radially.
