[Abstract]:Electrochemical sensor is one of the most active fields in the research of life science and clinical medicine testing methods. It has been widely used in the fields of clinical, industrial, environmental and agricultural analysis. The appearance, growth and maturity of nanoscience have provided a good premise for the development of electrochemical sensors. In recent years, the ratio of nano materials to nano materials is based on the ratio of nano materials. Large surface area, high surface reactivity, strong electrocatalysis ability and so on. More and more people use non enzyme electrochemistry and electroluminescent technology to construct a new non enzyme electrochemical sensor which can detect hydrogen peroxide and glucose. This paper is based on the advantages of nanocomposites and the sensitivity of electrochemical sensing technology. A new electrochemical biosensor with excellent electrochemical performance for glucose and hydrogen peroxide has been constructed, which widens the application field of electrochemical sensors. The specific contents are as follows: 1. a novel non enzyme electrochemiluminescence glucose sensor (La Ti O3-Ag0.1-modified-GCE) based on the perovskite nano composite material (La Ti O3-Ag0.1) is proposed. La Ti O3-Ag0.1 nanocomposites were prepared by the synthetic method of gel gel. The morphology and electrochemical properties of the nanocomposites were studied by a series of characterization methods (SEM, TEM, XRD) and electrochemical methods. The linear range and detection limit of the sensor on the detection of grape sugar were tested under the optimal experimental conditions. Its practical application.2. has studied an enzyme free electrochemiluminescence glucose sensor (Au-HS/SO3H-PMO (Et) -modified GCE). This energetic nanocomposite (Au-HS/SO3H-PMO (Et)) is supported by functional ordered mesoporous Kong Gui (Et). Gold nanoparticles are doped into the ordered mesoporous silica through the covalent bond, and Au nanoscale is used. A new type of non enzyme hydrogen peroxide sensor (Au-HS/SO3H-PMO (Et) -modified GCE) based on functionalized nano composite material (Au-HS/SO3H-PMO (Et)) was developed for the electrocatalytic oxidation of glucose. The electrochemical behavior of the modified electrode was investigated by a series of electrochemical testing methods, and the electrochemical behavior of the modified electrode was investigated. The electrochemical behavior of the modified electrode was investigated by a series of electrochemical testing methods. Under optimal conditions, the sensor has good response characteristics to the detection of hydrogen peroxide: high sensitivity, low detection limit, wide linear range, good selectivity and satisfactory practical application.4., a novel enzyme free glucose sensor based on HO-Bi ONO3 nanocomposite (HO) nanocomposite (HO) is constructed. -Bi ONO3-modified GCE). Using a series of characterization methods and electrochemical testing techniques, the morphology and composition of HO-Bi ONO3 nanocomposites and the detection of hydrogen peroxide by modified electrode were studied, and it was further applied to the detection of glucose in the actual blood samples.
