Qualitative detection, control and analysis of red blood cells (RBC) in a microfluidic channel by a commercially available 650 nm DVD laser pickup — •Max von Witzleben and Stefan Breuer — Institut für Angewandte Physik, Technische Universität Darmstadt, Schlossgartenstraße 7, 64289 Darmstadt, Germany

Commercially available DVD laser pickups are compact, robust and exhibit a good beam quality. They have been successfully employed in spatially controlling of cells by translating the laser beam inside a microfluidic channel by Kasurkurti et al. [1]. The full vertical control and contactless cell positioning however, was not possible due to constraints of the chosen experimental configuration. Here, we demonstrate experimentally that RBCs, placed in an appropriate solution can be fully controlled in 3 dimensions inside a tailored microfluidic channel. We experimentally access static and dynamic properties of RBCs based on a monolithic light detection configuration. [1] Kasukurti, A., Potcoava, M., Desai, S.A., Eggleton, C. and Marr, D.
