A team of Spanish researchers have developed, at the laboratory level, a prototype of a new biosensor to help detect breast cancer in its earliest stages. One of the team coordinators has been Ramón Martínez Máñez, a professor at the Universitat Politècnica de València (UPV) and the scientific director of the Networking Biomedical Research Centre in Bioengineering, Biomaterials and Nanomedicine (CIBER BBN). The other one has been Ana Lluch, a Valencian oncologist, co-coordinator of the Breast Cancer Biology Research Group of the INCLIVA Health Research Institute of the Hospital Clínic de València, and a member of the Networking Biomedical Research Centre in Cancer (CIBERONC). Their work has been published in the journal ACS Sensors.
