Abstract: A process for forming a carbon nanotube field effect transistor (CNTFET) device includes site-specific nanoparticle deposition on a CNTFET that has one or more carbon nanotubes, a source electrode, a drain electrode, and a sacrificial electrode on a substrate with an interposed dielectric layer. The process includes control of PMMA removal and electrodeposition in order to select nanoparticle size and deposition location down to singular nanoparticle deposition. The CNTFET device resulting in ultra-sensitivity for various bio-sensing applications, including detection of glucose at hypoglycemic levels.

Abstract: A gear shaft having a tubular body defining an axially extending cavity and an outer surface having a first engagement area for rotatably supporting a gear, and wherein a passage extends between the cavity and the engagement area for providing lubrication between the first engagement area of the gear shaft and the gear to reduce friction.
