High-sensitivity electrochemical sensing platform for acetaminophen based on MnS/Co3S4 hybrids doped electrochemically reduced graphene oxide nanocomposite

Scheme of MnS/Co3S4-ERGO preparation and detection of acetaminophen (AC). This protocol describes the preparation of manganese nanotubular MnS/Co3S4 by a hydrothermal method and their combination with electrochemically reduced graphene oxide (ERGO) to obtain MnS/Co3S4-ERGO nanocomposites. The composite suspension was then modified onto a glassy carbon electrode (GCE) and the resulting MnS/Co3S4-ERGO was successfully used for the ultrasensitive detection of AC.
