Fe2O3–MgO–CuO@MWCNT Nanocomposite for Highly Sensitive Electrochemical Detection of l -Cysteine at Low Potential in Biological Samples
A Fe2O3–MgO–CuO composite integrated with multiwalled carbon nanotubes (MWCNTs) was employed to develop a platform for the indirect electrochemical detection of l-cysteine (l-CYS). The material was characterized by XRD, FTIR, SEM, EDS, and EIS, confirming the formation of a hybrid nanostructure. After optimization of...
