Abstract:
Our research focuses on the development of analytical methodologies using electrochemical sensors based on disposable and low-cost screen-printed electrodes modified from the synthesis of carbon nanostructures, evaluating their electrochemical response for the determination of psychoactive substances by voltammetric techniques.
