NextGen-O2k Scientific developments


The revolutionary all-in-one instrument to conquer mitochondrial disease.

WP2: Scientific developments


The aim of this workpackage is to test measurement conditions for the newly developed modules and the development of specific applications.
  • Determination of optimal Q-sensor measurement conditions
  • Determination of optimal measurement conditions for the PB-Module
  • Development of protocols for scientific, pre-clinical and algal biotechnology applications
  • Data handling and quality control


Project Year 1: During testing in the first project year, optimal measurement conditions were determined for using the Q-sensor with a variety of biological samples. Simultaneously testing began of the beta version of DatLab. New SUIT protocols were developed for general, pre-clinical, and algal biotechnology applications. A focus has also been given to internal and external quality control measures.
