Subject

The combination of optical components and microfluidics is named optofluidics. The growing demand for faster and more sensitive analysis procedures in biology and medicine is constantly driving this area of research forward. E.g. with the aid of an optofluidic system blood can be analyzed for the concentration of certain bacteria.
A central task is the analysis of samples, which are flowing through the microfluidic channels as continues flux or droplets. Certain properties of the analyte are marked with fluorescent dyes and thus examined optically. This allows for example to sort proteins according to a specific property.
Goal is to miniaturize the analysis and integrate all optical components on-chip. This results in a lab-on-a-chip, which allows a compact and handy analysis procedure. This lab-on-a-chip devices are used in point-of-care testing (POCT). The most familiar example for a successful development towards a miniaturized POCT is the glucose meter.
In collaboration with the Institute of Biomaterials and Biomolecular Systems (IBBS) the research on optofluidics is carried out. The focus is on systems that enable a time resolved analysis.
