✦ Synopsis

In this paper we brie y describe new strategies to exploit self-assembled solid-state biomolecular materials as active elements of electronic devices. Two basically di erent approaches are proposed: a top-down approach, where biomolecular semiconductors consisting of DNA basis are self-organized and interconnected by planar metallic nanopatterns, and a bottom-up approach, where single or ordered matalloproteins are immobilized in a nanocircuit realizing a hybrid covalently bound biologic-inorganic system. The transport characteristics of di erent devices such as diodes, photodetectors and metalsemiconductor-metal structures will be described.
