    Abstract

    We report on a novel microfluidic system designed to monitor in real-time the concentration of live and dead cells in industrial cell production. Custom-made stepper motor actuated peristaltic pumps and valves, fluidic interconnections, sample-to-waste liquid management and image cytometry-based detection contribute to the high programmability and automation of this platform. Furthermore, this is to the best of our knowledge, the first use of Dean vortices to implement a wide range of dilution factors to highly concentrated cell samples. The combination of a curved channel geometry and high flow rates enables the rapid passive mixing and homogenization of the diluted cell plug.
