Abstract:
PURPOSE: A functionalization method of a single-walled carbon nanotube field-effect transistor (FET) by using a self-assembling peptide, a trimethylamine detection sensor containing a single-walled carbon nanotube FET manufactured by using the same, and a seafood freshness measuring method by using the sensor are provided to improve functions by combining a substance desired for detection with amino acid. CONSTITUTION: A semiconductor channel is constructed with single-walled carbon nanotubes. The single-walled carbon nanotubes are formed on a substrate. Source-drain electrodes are formed at both sides of the semiconductor channel. An amino acid cluster is combined with the terminus of a peptide. The peptide is self-assembled on the surface of the semiconductor channel.

PURPOSE: A reconfigurable semiconductor device is provided to easily absorb conductive nano particles on an oxide layer by forming a linker layer for absorbing the conductive nano particles for storing the electric charge of a semiconductor device. CONSTITUTION: A first insulation layer(130) is formed on a substrate(120). A first channel(140) with a first polarity is formed on the first plane of the first insulation layer. A second channel(150) with a second polarity is formed on the second plane of a second insulation layer. Terminal electrodes(161, 162) are respectively joined to the both ends of the first and the second channel. The second insulation layer(170A, 170B) is formed on the channels and the terminal electrodes. A charge storage layer(180) floats inside the second insulation layer and charges an electrical charge.

PURPOSE: An actin filament related nano device is provided to combine a plurality of actin filaments to a substrate with a carboxyl linkage by forming the area including a carboxyl end group on the substrate. CONSTITUTION: A substrate(200) is prepared. A non-polar area(210) is patterned on the substrate. The area including a carboxyl end group(220) is formed on the non-polar area. Actin filaments are attached to the area of the carboxyl end group. The substrate is selected from a group of gold, an oxide, silicon, quartz and a silicon nitride. The patterning includes a self-assembled monolayer patterning. The self-assembled monolayer patterning is performed by a micro contact printing or photolithography.
