Abstract
The advancement in nanotechnology has encouraged research into their application across various fields, including medical diagnosis. A currently expanding research area involves the utilization of nanomaterials in the development of electrochemical sensors for drug detection. This study focuses on the feasibility of using nano-oxides, specifically zinc ferrite, copper ferrite, and cobalt ferrite, in the fabrication of non-enzymatic electrochemical sensors to enhance the detection capabilities of paracetamol and cyclophosphamide. The ferrites, synthesized via the autocombustion method, underwent characterization utilizing Raman spectroscopy and field emission scanning electron microscopy to verify their synthesis accuracy and probe their morphological attributes, respectively. The synthesized ferrites manifested uniform morphology, with dimensions ranging between 30 to 50 nm.
These materials were subsequently utilized to functionalize the working electrode of commercially available screen-printed carbon electrodes through drop-casting technique
