    • It is worth to note that the main drawback of solid-phase PCR is the dimer formation through molecular crowding and primer interference, which result in poor PCR amplification efficiency with an average value between 1.0 and 1.4,36 whereas typical solution-phase amplification generally has an efficiency ranging from 1.6 to 2.0

    • Disposable carbon-based screen-printed electrodes are particularly well adapted for the goal of the work because they can be easily mass produced at low cost with a high degree of flexibility in the pattern design. Moreover, they possess low background current and good reproducibility

    • The programmed times for each temperature step of the cycle were made relatively long because of significant thermal inertia of the electrochemical cell. At 0.3 V s-1, it takes less than 5 s to record one voltammogram, so the overall cells of the array could be entirely scanned during the annealing step of each cycle

    • Among the different additives present in the commercialized DNA polymerase solution, surfactants used to stabilize the enzyme were suspected to affect the catalytic response by adsorption on the electrode surface. Unfortunately, in the absence of precise knowledge of constituents contained in the supplied proprietary enzyme solution, it was not possible to clearly identify the additive responsible for this phenomenon

    • The use of a commercial buffer was rendered possible because at the low anodic potential at which the catalytic oxidation takes place, there was no significant interference of chlorides ions brought by the buffer
