Our goal is to develop, validate and establish a simple method for the ‘molecular fingerprinting’ of blood samples, based on the use of an innovative, cutting-edge, ultrafast laser technology. At present, many types of cancer can only be reliably detected by careful examination of multiple tissue samples (biopsies). Our new method dispenses with the need for biopsies, as it is designed to detect the changes in the chemical composition of the blood that reveal the presence of cancer cells in the body, i.e. the cancer’s molecular fingerprint. Our efforts are primarily focused on the development of oncological diagnostics for the most common malignancies: cancers of the breast, lung and prostate gland.
