One drop of blood – less than one micro liter – is
sufficient to identify certain blood related metabolites.
The new technique,called MAILD, is based on classical mass spectrometry (MALDI-TOF/MS) andenables researchers to measure a large number of metabolites in biologicalsamples, opening doors for targeted and high-throughput metabolomics.Because of its versatile applications, also in medical diagnostics, the inventionis protected by patent.
