Abstract

Rapid detection of diseases such as cancer and diabetes or infectious diseases produced by bacteria or viruses is a field where biosensors and nowadays electronic languages have been used with great success. The determination of biological markers or pathogens quickly and in scenarios not restricted to clinical analysis such as during daily life activities or in bioterrorism actions is a goal still to be achieved. The portability of the equipment is one of the great limitations to achieve this goal. The Polymer Group Bernhard Gross of the Institute of Physics of São Carlos has a lot of experience in the field of sensors, biosensors and electronic languages. Currently works in the development of portable equipment based on electrical measurements and electrochemistry. With this objective the present project was developed for the assembly of a portable potentiostat with the use of chips and microprocessors to miniaturize the device, as well as the electric potential controller and the electric current meter. The prototype shall be autonomous and shall generate a variable electrical potential in the electrodes of the system, feed the electrochemical sensor(s), receive and map its response (s) and communicate with a data visualization and analysis apparatus. And so, be integrated with other parts of an electronic language, multiplexer, sensors and biosensors. (AU)
