The integrated micro optical sensor for photometry and fluorescence applications

摘要

In medical and pharmaceutical research and technology, the use of optical methods is already quite standard. By photometric and fluorescent analysis it is possible to identify and quantify even the smallest concentrations of different substances. The combination of micro-fluidics, optics and mechanics allows the development of systems with high value-creation potential, both for new and for common applications, especially in the area of "Health and Environment". Advanced research in the life sciences taking place less in the laboratory and more in the field is increasing the need for miniaturization of analytical devices. Such field environments place priority on portability, ease of use and reliability rather than the accuracy of measurements. This allows development of sensors and other components with reduced size and cost compared to high-end laboratory instruments. Additionally, multifaceted research projects, both in the laboratory and in the field, frequently require multiple analytical devices for monitoring or for the automation of various processes in situations where the use of expensive devices with increased accuracy are unnecessary or prohibitive for economic reasons. To support and accelerate research in Biology at the Ilmenau University of Technology a new opto-fluidic sensor was developed in cooperation with CiS research institute in Erfurt.
