I am Giovannina Barisciano, Ph.D at the University of Sannio, Benevento, Italy. I discussed my Ph.D thesis, entitled “Advanced label-free biosensors for breast cancer biomarkers detection in biological fluids” in July 2021. My Ph.D project, carried out in collaboration with several groups in a multidisciplinary venture, was aimed at the development of a label free optical fiber biosensor that allows the detection of tumor biomarkers in biological fluids and in particular in the circulating blood of patients with breast cancer. Actually, my interests are focused on the study of biological pathways and role of miRNAs in different types of cancers including colon and breast.
