A flexible parylene-based glutamate sensor

This paper presents the results of a study aimed at the fabrication and basic evaluation of a parylene-based flexible sensor for glutamate detection in the brain. We fabricated a flexible sensor using Micro Electro Mechanical Systems (MEMS) technology. Then, to modify the electrodes, we deposited an enzyme on the surface of the electrodes. To evaluate the function of the sensor, we performed an in vitro aliquot injection test. The fabricated flexible sensor was able to detect glutamate in vitro.
