AB Gold-metallic nanofibrils were prepared from three different iso-apoferritin (APO) proteins with different Light/Heavy (L/H) subunit ratios (from 0% up to 100% L-subunits). We show that APO protein fibrils have the ability toin situ nucleate and grow gold nanoparticles (AuNPs) simultaneously assembled on opposite strands of thefibrils, forming hybrid inorganic–organic metallic nanowires. The AuNPs are arranged following the pitch ofthe helical APO protein fiber. The mean size of the AuNPs was similar in the three different APO proteinfibrils studied in this work. The AuNPs retained their optical properties in these hybrid systems. Conductivitymeasurements showed ohmic behavior like that of a continuous metallic structure.
