Future Trends of Nanosensors
10.1 Introduction
The progression from macro- to nanosensors has been a very long and
interesting evolution (Khanna 2008, 2009). Several nanomaterials, notably
metallic nanoparticles (NPs), carbon nanotubes (CNTs), and quantum dots
(QDs), together with enabling nanotechnologies, duly supported by micro-
technologies have been exploited to realize nanosensors.
10.1.1 Interfacing Nanosensors with Human Beings
The core idea is to understand that a nanosensor is not necessarily a device
merely reduced in size to a few nanometers, but a device that makes use of
the unique properties of nanomaterials and NPs ...
