Problems solved by technology
[0003] In the past, liver function tests had to be done through blood tests, but the tests took a long time, and the results and monitoring could not be known immediately. Therefore, the development of non-invasive testing technologies can improve medical efficiency on the one hand, and reduce the cost of medical resources on the other. Waste is a technology with great potential and development, so it is urgent to develop a nano-sensing element with high stability and high sensitivity for detecting ammonia

Abstract
The invention discloses a preparation technique and application of an organic gas nanoscale sensing element, and relates to an ammonia nanoscale sensing element with a simple structure, high sensitivity and high stability. In the traditional live function test, various values must be detected through blood drawing, which is intrusive. The nanoscale element is prepared through an array anodic aluminum oxide (AAO) template, so that a non-intrusive test can be carried out; an organic gas sensor for ammonia is further designed, so that a patient can carry out self-monitoring; and therefore, through ammonia detection, the sensing element provided by the invention can send an early alarm for the health condition of the patient with a liver disease as early as possible.
Description
technical field [0001] The invention relates to the field of nanometer materials, and more specifically, relates to an ammonia nanometer sensing element and a preparation process thereof. Background technique [0002] Nowadays, with the continuous advancement of science and technology, human life is more comfortable and convenient than before, but such a rapidly developing life also brings many unknown injuries to the human body, among which liver disease is common in modern society and cannot be ignored of a disease. Liver disease is an inflammation of the liver caused by viruses, drugs, alcohol, or metabolic abnormalities, commonly known as hepatitis. According to the different symptoms, it can be divided into two types: chronic hepatitis and acute hepatitis. Among them, chronic liver disease and liver cirrhosis are one of the more serious diseases in modern society. Therefore, we should pay more attention to liver diseases. Since the liver is an organ without pain-sensi...
