| Sumario: | A rapid, accurate and reliable diagnosis is crucial for the identification of a disease, like cancer, where an early detection can improve patient survival outcomes. Cervical cancer is the third most commonly diagnosed and the fourth leading cause of cancer death in women. It is well known that persistent infections with high-risk human papillomaviruses (HPV) are the primary cause of cervical cancer. Electrochemical DNA biosensors have received important attention owing to their characteristics. Moreover, their compatibility with microfabrication technologies makes them attractive for DNA diagnostics. The first objective of the work described in this thesis is the development of an electrochemical DNA sensor array for the multiplex detection of high-risk HPV sequences (HPV16, 18 and 45) and its application to human clinical samples. A second objective is the demonstration of a proof-of-concept of the development of isothermal (helicase-dependent amplification) solid-phase amplification methods with electrochemical real-time monitoring. |
