Physarum Polycephalum changes polyaniline properties

Physarum polycephalum slime mould can modify polyaniline (PANI) features due to its internal activity. We created networks with different conductivity made by the slime mould on PANI substrates. Thus, Physarum's growth results in changing the conductivity state of PANI layers, providing negative and positive patterning of the samples. A spectrophotometric scanner is here exploited to investigate and characterize the effects coming out from the interaction between Physarum polycephalum and PANI. The latter is an electro-chromic polymer that vary its colour and conductive properties according to its redox state.
