Goal of this project is to demonstrate a miniaturised system which allows marker-free optical analyses and sorting at cell level with a minimum amount of analyte. Particles are guided through the optical resonator of a semiconductor laser diode, integrated on a microfluidic module out of polymer and glass. Particles can be detected by evaluation of different laser parameters e.g. wavelength shift or threshold current. After analysing the particle, integrated optical traps are used for sorting the particles. Within this project first prototypes of the module will be created and characterized.

This project is done in close collaboration with the Institute of Optoelectronics at Ulm University and is funded by the Landesstiftung Baden-Württemberg.
