Abstract: Even if cancer specific biomarkers are present in peripheral blood of cancer patients, it is very difficult to detect them with conventional technology because of their low concentration. A potential cancer biomarker is the HMGA1b protein, whose overexpression is a feature of several human malignant neoplasias. By taking advantage of the surface plasmon resonance (SPR) phenomenon, we realized a specific nano/technology-based assay for cancer detection. More in details, anti-HMGA1b monoclonal antibodies, whose affinity was previously defined by ELISA, were immobilized onto metallic surfaces to develop a direct SPR-based assay. After having analyzed blood samples from colorectal cancer patients and healthy people for the presence of HMGA1b, we observed a 2-fold increase of the HMGA1b levels in the blood of cancer patients with respect to the healthy control people. We conclude that the set-up technology might allow to detect a tumoral mass through the evaluation of HMGA1b protein blood levels.
