    Sensitive and selective non-enzymatic rGO/ZIF-8 hybrid composite-based electrochemical sensor for uric acid detection: optimisation by response surface methodology by Suratman, Anis Afiqah, Che Zakaria, Aida Zafierah, Abdul Aziz, Siti Fatimah Nur, Alang Ahmad, Shahrul Ainliah

    Published 2024
    “…A central composite design was employed to examine the influence of three independent variables, i.e., volume, pH and deposition time to provide an insight into the sensing performance of the ZIF-8/rGO electrode.This ZIF-8/rGO hybrid exhibited a timely response to uric acid within a linear concentration range of 20 to 400 μM, achieving a detection limit of 0.97 μM and demonstrating excellent selectivity. …”
