Leukaemias are haematopoietic tumours resulting from genetic aberrations that lead to biochemical, proteomic and metabolomic changes. Diagnosis is based on a complex procedure involving the identification of genetic changes and phenotypic leukaemia cells. The aim of this project is to create a microfluidic diagnostic device with SRS-based detection technology (Stimulated Raman Scattering), followed by its clinical implementation. Through the interaction of multidisciplinary teams, the Consortium will conduct multi-faceted studies of Ramanian leukaemia cell spectra and link them to the biological-clinical features of the disease. The developed diagnostic algorithm combined with a unique device will allow for rapid analysis of leukaemia cells and sorting them without using fluorescent markers. The device should allow rapid, objective and cheaper diagnosis at the stage of diagnosis and during the treatment of the disease.
