Problems solved by technology

Although these methods have different advantages, there are still deficiencies. For example, the above method requires specific equipment for the detection of glucose concentration, and the equipment itself is relatively expensive and not economical; universality
In addition, the above-mentioned method has a long measurement cycle, and the analysis process is relatively complicated, so it is impossible to realize the real-time measurement of glucose.

Abstract

The invention discloses a method for detecting glucose by paper-based colorimetry, which comprises the following steps: making a self-made colorimeter; designing a hydrophobic wax printing pattern; cutting filter paper; printing the hydrophobic wax printing pattern on the filter paper; melting wax into shape; preparing ZnFe 2 o 4 ; Prepare mixed solution; Add the mixed solution dropwise to the detection pool; Add the measured solution dropwise; The method for detecting glucose of the present invention is simple to operate, can be operated without professional technicians, has high detection speed, low cost, and simple post-treatment without pollution.

Description

technical field [0001] The invention relates to a paper-based colorimetric detection method for glucose, which belongs to the technical field of glucose detection. Background technique [0002] As the main component of blood sugar in the human body, glucose provides the main energy source for human activities, and its level directly affects people's physical condition. Among them, the harm of high blood sugar to human health is more and more serious, such as obesity, diabetes and other diseases. At present, diabetes has become the third major disease threatening human health after cancer and cardiovascular disease. According to the survey results of relevant international organizations in 2010, the number of diabetic patients in the world has reached 285 million, and the number of diabetic patients is still on the rise. At the same time, diabetes will also produce a variety of complications, such as cerebral infarction, cerebral hemorrhage, high blood pressure, etc., which...
