    Can voltammetry improve the reproducibility of drop casted surfaces?
    However, meaningful voltammetry requires the formation of uniformly modified surfaces for which the coffee ring and its related effects, which are overviewed, present a significant limitation on the reproducibility of the drop casted surfaces. Approaches for amelioration of the coffee ring effect by various methods are discussed.

    In situ modified electrodes - ScienceDirect
    Traditional modified electrodes are prepared by drop-casting method, which usually results in aggregation of the catalytic particles and the formation of multilayered electrode surface. We herein propose a new in situ modification approach by dipping the electrode in a suspension of diluted nanopart...

    Intrinsic electrochemical performance and precise control of surface porosity of graphene-modified electrodes using the drop-casting technique
    Graphenes have for a long time been shown to exhibit enhanced electrochemical sensing and fast heterogeneous electron transfers, but the nature of such improved electrochemistry is disputed due to its inherent porosity. Adsorption and thin layer effects may additionally contribute to the observed be...
