Spatially selective removal of single-walled carbon nanotubes from a random nanotube network is demonstrated. The method simply involves local irradiation of a low-acceleration-voltage electron beam and annealing in air, and could be applied for the fabrication of a various kinds of nanotube networks. Raman spectroscopy measurements showed that the(More)
What we believe to be a new label-free multichannel biosensing platform is proposed. It is composed of surface-immobilized gold nanospheres (SIGNs) above a gold surface with a nanogap supported by a merocyanine self-assembled monolayer. The circular SIGN spots with a diameter of 120 microm were arrayed for multichannel biosensing on a glass slide. Two kinds(More)
We have investigated linear and nonlinear optical properties of surface immobilized gold nanospheres (SIGNs) above a gold surface with a gap distance of a few nanometers. The nanogap was supported by amine or merocyanine terminated self-assembled monolayers (SAMs) of alkanethiolates. A large second-harmonic generation (SHG) was observed from the SIGN(More)
