Nanotechnology: applications in sensors, field emission and others

Abstract

Nanomaterials offer a large surface area and thus large adsorption rates for gases and vapors.If this can lead to a measurable change in some property of that material,then it forms the basis for cemical sensing.In contrast,for biosensing,it is preferable to use a"lock and key" approach:that is to choose aprobe that will be specific to the target of interest,thus ensuring selectivity.This talk will discuss chemical and bio sensor developments.CNTs and many nanowires are good candidates for field emission and thus have been investigated for flat panel displays,instrumentation and others.This topic will also be covered.
