Abstract
Ferritin and neuromelanin are present within the dopamine neurons of the substantia nigra pars compacta (SNc), and ferritin is also distributed in the intercellular regions of those neurons. It is has been shown that ferritin has electron transport behavior that is the same as electron transport properties of semiconductor quantum dots, and neuromelanin also has similar physical characteristics to the physical characteristics of semiconductor quantum dots. Based on the distribution of ferritin and neuromelanin in the SNc, it has been hypothesized that they could support electron transport in the same manner as disordered or semi-ordered arrays of quantum dots, and that such behavior could be detected from the results of conductive atomic force microscopy (c-AFM) testing. This data article provides the c-AFM measurement data as reported and discussed in "Indication of quantum mechanical electron transport in human substantia nigra tissue from conductive atomic force microscopy analysis."
