Electrochemical sensors and biosensors can enable disease diagnosis in a fast and accurate manner, using easy manufacturing and handle devices. The need to use new methodologies for the detection of diseases makes the development of these sensors viable. The electrochemical techniques also present some advantages as the low instrumental cost and high sensitivity, allowing the detectability of species in biological samples, with accurate and reliable results in short time periods, compared to other conventional methods used for the detection of diseases. Thus, using PLA polymer and graphene, we intend to make 3D printed electrodes and apply in the determination of biomolecules/biomarkers related to the presence of allergies and diseases. The biosensors will be used in the development of alternative analytical methodologies, by the incorporation of antibodies for the detection of BSA (Bovine Serum Albumin), related to allergies caused by cow milk; and IgG antigen for detection of Yellow Fever virus. Furthermore, it is intended to carry out the electrochemical detection of biomarkers related to Alzheimer's Disease. It is expected to obtain sensitive, selective and robust devices, which present high detectability for these species. (AU)
