Dosage of glucose released from the textile material in a finishing bath
A novel spectrophotometric chemical solution for evaluating enzymatic activity after treatment with a cellulase-type enzyme on a cellulosic textile. This solution is based on the chemical reaction that occurs between sodium picric acid hydroxide and a glucose solution. The color change of this mixture indicates the presence of glucose, and the intensity of the color reflects the amount of glucose released. First, the textile material is cleaned at 45°C using a detergent and an anti-depositing agent. Then, it undergoes an enzymatic treatment with a cellulase-type enzyme, and a small amount of the final enzyme bath is collected. The actual assay step then begins by adding a predetermined volume of sodium hydroxide picric acid and the final enzyme bath to a test tube and heating it at 100°C for 20 minutes. Finally, after cooling, the mixture is analyzed with a spectrophotometer, the absorbance is measured, and the exact rate of glucose released is calculated. This method has proven its effectiveness and applicability in the textile industry, using a cellulosic base and a cellulase-type enzyme.

A glucose solution-stable calcium phosphate ion cluster, its preparation method and application
This invention relates to the field of dental restoration technology, providing a glucose solution-stabilized calcium phosphate ion cluster, its preparation method, and its application. The invention utilizes a glucose solution to stabilize calcium phosphate ion clusters. In a high-concentration glucose aqueous solution, calcium ions and phosphate groups aggregate to form ion clusters. Upon contact with saliva, the glucose dissolves, releasing the calcium phosphate ion clusters, which then attach to the enamel prism structure of the tooth, triggering a mineralization reaction. This promotes the deposition and growth of calcium phosphate crystals along a specific orientation, restoring the original morphology of the tooth and improving the strength and hardness of the enamel. Furthermore, the glucose solution used in this invention stabilizes the calcium phosphate ion clusters, resulting in clusters with a size <2 nm, allowing them to penetrate nanoscale demineralization pores and easily penetrate enamel micropores. This results in high mineralization efficiency, high enamel restoration strength, and the mineralization process does not require high temperature, high pressure, or ultraviolet irradiation, exhibiting good biosafety and high clinical translation feasibility, thus possessing broad application prospects in the field of dental restoration.
