Left‐Handed Metal Microcoil: Fabrication of Left‐Handed Metal Microcoil from Spiral Vessel of Vascular Plant (Adv. Mater. 46/2011)

Abstract

Spiral vessels extracted from plant tissues can be utilized as a biotemplate for the production of left-handed metal microcoils with approximately 50-µm coil diameter. The silver microcoil functions as a solenoid with small self-inductance ranging to the picohenry level. As reported by Kaori Kamata and co-workers, this method provides an environmentally conscious and cheap route to develop electromagnetic-responsive materials such as microantenna targeting the high-frequency region.
