Thomas van Oordt studied Chemistry at ZHW Zurich and Micro- and Nanotechnology at Vorarlberg University of Applied Sciences. He has several years experience in the chemical industry developing production methods for active pharmaceutical ingredients. Since 2009 he has been a project leader at HSG-IMIT in Freiburg, Germany with a focus in centrifugal microfluidics.


The worlds growing mobility, mass tourism and the threat of terrorism has tremendously increased the risk of rapid spread of infectious microorganisms and toxins. Therefore, there is a continuously growing demand for small, mobile, and easytouse diagnostic systems for the automated detection of infectious and lethal agents directly at the point of need. However, the currently used technologies for pathogen detection require relatively large instruments, complex bio analytical procedures and highly skilled analysts, which seriously limit the rapid and efficient response, as desired for the effective tacking of emergency situations. We have developed a potential centrifugal lab on a chip (LOAC) system for the automated detection of biological threats. It involves the Lab Disk platform and a portable fully automated LOAC system that performs complex biochemical analyses at the point of need. It was employed for the detection of Botulinum neurotoxin by automated luciferase reporter assay in addition to the detection of Bacillus anthracis and Francisella tularensis by nucleic acid analysis. The reporter assay detects Botulinum neurotoxin in samples such as milk, soup and blood plasma in the concentration range of 8 pM-6 nM in less than 30 minutes. It is based on the detection of the proteolytic activity of the toxins light chain, the purified toxin as well as the toxin in multiprotein complex form. On the other hand, the nucleic acid analysis detects Bacillus anthracis and Francisella tularensis via isothermal polymerase amplification in less than 45 minutes.
