Abstract

The invention relates to a three-dimensional inverse opal polymer photonic crystal material and a preparation method and application thereof, and belongs to the technical field of chemical and clinical analysis detection of glucose. According to the three-dimensional inverse opal polymer photonic crystal material, a polymer of an inverse opal structure is mainly prepared through a polymerization reaction of a functional polymerization monomer and a crosslinking agent, and the functional polymerization monomer is 3-acrylamidophenylboronic acid. The three-dimensional inverse opal photonic crystal material has good optical performance, and the material is a photonic crystal gel material which generates reversible change with external stimulation, has excellent expansion and recovery properties, and has fast response; and the content of glucose can be detected with high selectivity sensitively and quickly in real time, and the three-dimensional inverse opal polymer photonic crystal material is especially suitable for convenient detection of the level of human urine sugar, and excellent recyclability is achieved.

Description

technical field [0001] The invention relates to a three-dimensional inverse opal polymer photonic crystal material and its preparation method and application, belonging to the technical field of chemical and clinical glucose analysis and testing. Background technique [0002] Diabetes has become one of the serious diseases that endanger the health of all human beings, and gradually shows two trends: the number of patients is increasing year by year and the age of patients is getting younger. Therefore, in order to control the harm caused by diabetes, countries all over the world have invested huge manpower and material resources. Real-time monitoring of blood sugar levels is a common means of controlling diabetes, but the current general detection methods require blood samples to be collected, which not only brings physical pain to patients, but also brings them psychological pressure. Therefore, non-invasive glucose detection methods have become one of the most extensive r...
