Nanosensor technology is developing rapidly and is the subject of a global research effort. This paper provides the state of the art in nano-sensor technology from the device perspective, by explaining the details of the architecture and components of individual nano-sensors, as well as the existing manufacturing and integration techniques for nano-sensor devices. Nano-sensor research is making a two-directional progress,firstly in evolving new sensors employing macroscopic phenomena, and secondly in the performance enhancement of existing sensors. These nano-sensors have been classified into physical and chemical categories, with the bio-sensors placed on borderlines of biological signals with the remaining classes. Although probes for scanning and atomic force micro copies still lead the commercially available nano-sensors.Some new nano-sensors, resulting from multidisciplinary research, are beginning to make their way to the market place. Focusing on the salient developments in nano-sensors from the viewpoints of novel materials, device structures and functionalities introduced, the paper highlights the significant milestones crossed and elucidates emerging future prospects in this area.
