Methadone is one of the prescription opioid drugs which is widely used in addiction treatment programs. It is an electroactive material and can be measured through electrochemical methods. Simple co-precipitation method was the preparation route of nanomaterial synthesis. Cyclic voltammetry was applied for studying the modified electrode performance and square wave voltammetry was chosen as the detection technique. The limit of detection of the proposed method was 2.8 µmol L-1 of methadone. The method is able to detect methadone molecule in human plasma samples precisely. }, keywords = {Cerium lanthanum ferrite nanoparticles,Carbon paste electrode,Methadone,Voltammetry,sensor}, url = {https://www.abechem.com/article_704568.html}, eprint = {https://www.abechem.com/article_704568_d1a0243963851bd5f80e7ba6b5567e28.pdf} }
