Savitzky–Golay processing and bidimensional plotting of current–time signals from stochastic blocking electrochemistry to analyze mixtures of rod-shaped bacteria

Abstract

Rod-shaped bacteria generate single-steps when blocking reactions at ultramicroelectrodes. A Savitzky–Golay filter renders easy-to-integrate peaks providing step current (Δi) and duration (Δt) to analyze bacterial mixtures using bidimensional plots.
