  Proteinoids, or thermal proteins, are inorganic entities formed by heating
amino acids to their melting point and commencing polymerisation to form
polymeric chains. Typically, their diameters range from 10 to 100 micron. Some
amino acids incorporated into proteinoid chains are more hydrophobic than
others, leading proteinoids to cluster together when they are present in
aqueous solutions at specific concentrations, allowing them to grow into
microspheres. The peculiar structure of proteinoids composed of linked amino
acids endows them with unique properties, including action-potential like
spiking of electrical potential. These unique properties make ensembles of
proteinoid microspheres a promising substrate for designing future artificial
brains and unconventional computing devices. To evaluate a potential of
proteinoid microspheres for unconventional electronic devices we measure and
analyse the data-transfer capacities of proteinoid microspheres. In
experimental laboratory conditions we demonstrate that the transfer function of
proteinoids microspheres is a nontrivial phenomenon, which might be due to the
wide range of proteinoid shapes, sizes, and structures.
