Kind situation is clinically known as hypoglycemia.When fasting plasma glucose concentration is less than 6.8molL-1When, it may appear that more drinks, diuresis, more foods,
It the symptoms such as but becomes thin, or even has the danger for being converted into diabetes.Therefore, the detection of glucose is of great significance.
Biosensor (biosensor) is a kind of sensitive to biological substance and its concentration is converted to electric signal progress
The instrument of detection.Since Updike and Hicks in 1967 has made first biosensor glucose sensor, biology
Sensor has significant progress, national economy each department for example food, pharmacy, chemical industry, clinical examination, biomedicine,
Environmental monitoring etc. has a wide range of applications.First generation biosensor is to carry out electron transmission using oxygen as electronic media, will
Concentration of glucose is converted into electric signal, and to detect concentration of glucose, but this kind of biosensor is influenced by partial pressure of oxygen
Greatly, the phase factor time is long, it is difficult to carry out in-vivo analysis.Second generation biosensor solves the defect using oxygen as electronic media, makes
With new substance, such as antibody, receptor protein, electroactive substance be as electronic media, but this kind of mediator is easily dirty
Contaminate electrode.And Third Generation Biosensors are then directly using enzyme as medium, this kind of electronic media has specificity, can be well
Glucose is detected, but enzyme mutability, directly transmission are difficult.Electrode material is always the core of biosensor, also influences life
The key indexes such as cost, the performance of object sensor.Currently, the electrode material of biosensor has from enzymatic activity substance to high property
The trend that energy, more stable non-enzymatic material change.Certain metals have catalytic activity to glucose, it is necessary to improve application to it
In the detection of glucose.
