Bu
çalışmada, propranololün elektrokimyasal davranışı, indirgenmiş grafen oksit
(rGO) ile modifiye edilmiş yüzey baskılı karbon elektrotlar (SPCE) ile
incelenmiştir. Oksidasyon işlemi, döngüsel voltametri (CV) ve diferansiyel puls
voltametri (DPV) teknikleri kullanılarak gerçekleştirilmiştir. Sonuçlar,
rGO'nun oksidasyon pik akımını artırarak bu ilaçları uygun potansiyellerde
oksitlediğini göstermiştir. Modifiye edilmiş SPCE, beta-blokerlerin, fosfat
tampon çözeltisinde (PBS) alışılmadık derecede pozitif bir potansiyelde
oksidasyonuna doğru mükemmel katalitik aktivite sergilemiştir. Propranololün
tespiti için önerilen sensörün doğrusal konsantrasyon aralığı ve tespit limiti,
sırasıyla, 50 µM ve 2.61 µM olarak elde edilmiştir.
