                         carbon nanotubes and graphene oxide (VACNT-GO) as the electrode 
                         material is proposed. The VACNT-GO electrode was synthesized using 
                         a microwave-assisted chemical vapor deposition method followed by 
                         oxygen plasma treatment. The VACNT-GO electrode presented 
                         superhydrophilic behavior and fast charge transfer, which are very 
                         attractive for electrochemical applications. The RC molecule 
                         presented an oxidation process at +1.26 V vs. Ag/AgCl (3.0 mol L-1 
                         KCl) in phosphate buffer solution (pH 2), and this redox behavior 
                         was explored for its voltammetric determination. Using square-wave 
                         adsorptive anodic stripping voltammetry (SWAdASV) under optimized 
                         conditions, the analytical curve was linear in RC concentration 
                         range from 0.48 to 46.72 \μmol L-1 with a limit of detection 
                         of 0.06 \μmol L-1. The developed SWAdASV method was applied 
                         for RC quantification in commercial pharmaceutical samples, and 
                         the results are consistent with those obtained by the comparative 
                         spectrophotometric method at a confidence level of 95%. Moreover, 
                         RC was determined in human body fluid samples of urine and human 
                         serum.",
