Optical, Nanomechanical and Electrochemical Sensing on a DVD Disc
Cantilever-like sensors have been integrated on a disc  and we now have a method of obtaining large amount of data – allowing us to do statistics on the measurements. Currently, we are studying the specific detection of biomarkers, such as suPAR . Additionally, we try to implement optical microscopy on the spinning platform in order to study and count larger objects such as cells. In this way it will be possible to analyze a given sample for several parameters simultaneously.
Electrodes can also be integrated on the spinning platform  and hereby it is possible to perform electrochemical measurements at the same time as having the benefit of the centrifugal liquid handling. As an example it is simple to measure in flow conditions and to perform continuous cyclic voltammograms in different concentrations of electrolytes using built-in valves.
In conclusion, the merger of sensors and centrifugal microfluidcs combined with sensitive and compact read-out possibilities from optical pick-up heads makes it possible to realize full sample pretreatment and read-out in a both fast and compact manner.
