Our research focuses on the use of flexible microstructures created by two-photon polymerization in biomedical and microfluidic applications. Optical tweezers can be used to manipulate the microstructures when needed.

Microscopic viscometers

Soft photopolymer viscometers were developed for use in microfluidic environments. The viscosity of liquids was assessed by observing the Brownian fluctuations of microbeads attached to the end of flexible cantilevers.

A family of soft micro-robots was developed for indirect optical manipulation of individual cells. The presented applications include cell collection, 3D cell imaging, and spatially and temporally controlled cell–cell interaction.
