8Chemical Nanosensors
8.1 Introduction
The question may be raised that, during description of physical sensors, chemical phenomena are frequently intermixed; e.g., in Sections 6.7.2 and 6.7.3, pH nanosensors were dealt with. It is well-nigh impossible to tightly compartmentalize the discussion into physical, chemical and biological domains, such that chemical and biological phenomena do not enter the domain of physical sensors. Similar remarks are applicable to chemical and biological sensors. Nor does it happen in reality or in a real-world situation, that one particular type of phenomenon occurs in total isolation. Nonetheless, it provides a description of events, in which chemical phenomena are at the forefront, with physical/biological ...
