Abstract
Microfluid segments allow the efficient realization and application of well-separated test volumes for high-resolved and multidimensional investigations. With typical volumes in the nanoliter and lower microliter range, screening runs with several hundred up to several thousand single volumes can be realized with a total consumption of less than 1 mL test solution. The fluid segments act as confinements for the determination of the dose-related cell response on different effectors which can be applied in a precision better than 1% in concentration. One, two, or higher dimensional concentration spaces are addressed by PC-controlled low-pulsation syringe pumps. Micro flow-through photometric measurements allow the characterization of the quality of segment sequences and the determination of up to four optical channels with typical measurement frequencies between 500 and 5,000 Hz. The generation and characterization of microfluid segment sequences for screening purposes, the realization of different concentration spaces for the determination of effects of single substances and combinatorial effects, and the cultivation of different organisms are reported. The investigations have shown the applicability of micro segmented flow for fast microtoxicological screenings with prokaryotic and eukaryotic microorganisms like E. Coli, Chlorella vulgaris, and Saccharomyces cerevisiae and for multicellular systems like embryos of Danio rerio.
