Owing to the incidence of diabetes, glucose sensing in diabetes diagnosis
and therapy is of great significance. In addition, in the drug and food sectors, glucose
sensing is also important. Via different techniques, such as electrochemical or optical
approaches, glucose sensing has been achieved. Sensors play an important role in the
identification of chemical and biological samples and have attracted a great deal of
interest in recent decades. Signals are produced by the binding of the analytical sensor.
Varieties of chemical sensor, including cationic and anionic sensors, are used. In
chemical sensing, molecular recognition and molecular transduction exist. There are
three pieces of a chemo sensor, the binding site receptor, the device whose properties
change with the binding and the spacer. The advanced glucose sensors development
with high sensitivity and suitability has been facilitated by novel transducers made with
nanomaterials that combine fluorescent methods. Glucose detection by a chemo sensor
is discussed in this chapter. In addition, techniques for combining biological sensing
and fluorescent nanomaterials components are explored, and the applicability of the
chemosensor is also illustrated, making it suitable for glucose sensing. It is concluded
that the extensive use of chemosensors in the health care sector makes them convenient
instruments for real-time identification and long-term tracking of the environmental,
biological and physical state of the human body.
