1Introduction to Nanosensors
1.1 Getting Started with Nanosensors
This book deals with nanosensors of three key types of signals, namely, physical, chemical, and biological. So, the questions that immediately come to mind are as follows: (1) What is nanotechnology? (2) What are nanosensors? and (3) What is the meaning of the terms ‘physical,” “chemical,” or “biological” alone or when applied to nanosensors?
These questions need to be answered at the outset. Clearly, the starting point in the study of nanosensors will be the basic concepts of physics, chemistry, biology, and nanotechnology Semiconductor electronics will also be introduced. The key terms will be defined. These will enable the reader to recapitulate the preliminary knowledge required ...
