Abstract
AbstractThe current work aimed to fabricate a new cocaine sensor of octahedral palladium‐doped cobaltite composite (Oh‐Pd2+ : Co3O4‐C) using a simple hydrothermal protocol. As‐fabricated cocaine sensing approach was validated by various methods. Energy dispersive X‐ray analysis, X‐ray diffraction and scanning electron microscopy were recruited to characterize our charged modified composite. The electrode could sensitively detect cocaine, with a lengthy linear range (0.01 μM–900.0 μM) and a limit of detection (1.3 nM). The quantitative cocaine determination was achieved in the biological specimens using our modified electrode, the results of which displayed admirable outcomes.
