Abstract: Inter-allotropic transformations of carbon are provided using moderate conditions including alternating voltage pulses and modest temperature elevation. By controlling the pulse magnitude, small-diameter single-walled carbon nanotubes are transformed into larger-diameter single-walled carbon nanotubes, multi-walled carbon nanotubes of different morphologies, and multi-layered graphene nanoribbons.

Abstract: Provided are a flexible biosensor using a gold binding substance and a method for manufacturing the same. The flexible biosensor includes: a flexible substrate; a silicon substrate which is formed on the flexible substrate and on which source and drain regions doped with a first type impurity are formed with a predetermined gap; and source, drain and gate electrodes which are formed on the silicon substrate and comprise gold, wherein, on the gate electrode, a fused protein which is formed by fusion with a gold binding substance specifically binding to gold is immobilized. Since the biosensor is embodied on a flexible substrate, it may effectively overcome the limitation of the existing biosensor embodied on a silicon substrate.
