Simultaneous determination of ascorbic acid, dopamine, uric acid and folic acid based on activated graphene/MWCNT nanocomposite loaded Au nanoclusters

- A novel nanocomposite sensor AuNCs/AGR/MWCNT was successfully fabricated.
- The sensor was employed for simultaneous determinations of AA, DA, UA and FA.
- The application was conducted for human urine real samples.
