The first graphene-based electrochemical nanosensor was constructed for the sensing of MTP.
GRE/PtNPs/NFN sensor exhibits superior electrochemical activity towards the electro-oxidation of MTP.
The significantly lower detection limit was observed among the carbon-based electrochemical sensors used in the analysis of MTP, up to now.
GR/PtNPs nanocomposite was synthesized by single-step reduction method.
The proposed sensor was successfully applied for the analysis of MTP in drug samples.
