We propose an unconventional way of analysing quantum transport (Coulomb-Blockade)
experiments in nanostructures, based on universal scaling properties of the electrochemical
potentials. Firstly, we show the existence of such scaling relations theoretically. Then, by direct
comparison of theoretical and experimental data, we show that they can be used to accurately
determine the different charge/confinement regimes achievable in an experiment. We
demonstrate our approach with the analysis of experiments in traditional semiconductors (e.g.,
GaAs), as well as novel 2D materials. Finally, we discuss the possibilities of scaling-up our
approach from a single system to on-chip arrays of nanostructures of scalable architecture.
