The plasmodium of the slime mould Physarum polycephalum has recently received sig-nificant attention for its value as a highly malleable amorphous computing substrate. In laboratory-based experiments, micro- and nanoscale artificial circuit components were introduced into the P. polycephalum plasmdodium to investigate the electrical prop-erties and computational abilities of hybridised slime mould. It was found through a combination of imaging techniques and electrophysiological measurements that P. poly-cephalum is able to internalise a range of electrically active nanoparticles, assemble them in vivo and distribute them around the plasmodium. Hybridised plasmodium is able to form biomorphic mineralised networks, both inside the living pla...
