Abstract Diagnostic techniques for early cancers of different types of cancer are of great relevance, given that cancer is the third most common cause of death in developing countries. One of the strategies to identify the disease is to detect biomarkers with biosensors, such as those based on measurements of electrical impedance and capacitance. This type of biosensor allows the detection of analytes without using markers and with little treatment of the sample under analysis. This project intends to produce inexpensive printed interdigitated electrodes for capacitive biosensors used in the detection of cancer biomarkers. The electrodes will be produced with screen printing on cheap and flexible substrates, such as plastic and paper. To construct the biosensors, the electrodes will be covered with different nanomaterials aiming at the optimization of the electrical and analytical properties. (AU) | |
