The Langmuir-Blodgett(LB) technique or self-assembled monolayer(SAM) allows to form ultra-thin films on the soft materials such as biological functional proteins or nano-sturucure substances, without damaging their functions. In this research, we have developed the methods establishing electrical contact to soft materials by employing electrical conducting LB films and SAMs. Applying these methods, we have fabricated several new devices including biosensors and molecular devices.
