Development of disposable devices with conductive inks and low-cost substrates for the biosensing of hormonal dysfunctions and malaria detection

Electrochemical devices that allow fast, miniaturized and highly sensitive analyzes are one of the areas that have gained prominence in recent years. Conductive inks aligned with inert substrates allow the creation of these miniaturized electrochemical devices. In this project, it is intended to make disposable sensory and biosensory architectures, with relatively low cost materials. For the manufacture of conductive inks, a polymeric base aligned with a solvent will be used, which can be water or organic solvents, and a conductive material, which can be carbonaceous materials or even metals, such as silver and copper. The different inks manufactured can also have their surface modified, resulting in an increase in the electrochemical area, in addition to a reduction in the detection limits of these disposable devices. The modifications not only allow for an improvement in relation to the sensing of these devices, but also, with the aid of agents that form covalent bonds, they can be a means for the manufacture of biosensors. There are many diseases that require a quick and efficient diagnosis. Hormonal disorders call our attention, since they are related to several diseases, among them one of the biggest causes of death in women, Breast Cancer. Malaria is another aspect that we want to research, since immunosensing in place and quickly can reduce the mortality rates of this disease. Thus, it is intended to develop disposable and miniaturized systems that will be tested for the sensing of neurotransmitters and biosensing of Malaria and estrone, diseases that directly affect human health.
