Screen-printed Electrochemical Immunosensors for the Detection of Cancer and Cardiovascular Biomarkers

Electrochemical immunosensors (EIs) for the determination of disease biomarkers has attracted a wide interest due to its high sensitivity, low cost, and possible integration in compact analytical devices. The use of screen-printed electrodes (SPEs) to develop EIs contributes to the great potential they have in point of care (POC) test, since SPEs show good electrical properties and allow the reduction of the electrochemical instrumentation down to small pocket-size devices. Moreover, during the last years, SPEs have gone through significant improvements related to both their design and printing materials. Since cancer and cardiovascular diseases are the major threats of global health, there is a growing demand for the development of portable, rapid, simple and inexpensive devices for the detection of these diseases. This article presents an overview about the main biomarkers of cancer and cardiovascular diseases and the EIs based on SPEs for the detection of these biomarkers.
