Given the clinical need for improved in vitro molecular diagnostic technologies for brain tumor biopsies, the research team combined the advantages of microfluidics and microscopy-based cell imaging to develop the microfluidic image cytometry platform. The new platform provides multiparameter, single-cell signaling measurements (fingerprints) of brain tumor samples. The ability to measure these molecular fingerprints on small samples marks a new advance in molecular diagnostics that will enable predictive and personalized medicine.
