3 results about "Eosin Y" patented technology

This invention relates to the field of medical testing, and particularly to a Wright-Gymsza staining solution and its application. The Wright-Gymsza staining solution of this invention comprises staining solution A and staining solution B. Staining solution A mainly consists of eosin Y, azurite-eosin A, methylene blue, cell fixative, and stabilizer, while staining solution B is a buffer solution. Experiments have shown that the Wright-Gymsza staining solution of this invention can stain normally for 27 months after preparation, solving the technical problems of uneven staining and dye residue on the staining platform after a period of time after opening.

This invention discloses a method for preparing a Zr-MOF catalyst containing a Co single-atom site, belonging to the field of metal-organic framework synthesis and advanced oxidation catalysis technology. First, mesoporous Zr-MOFs (NKM-508) are prepared via a solvothermal method using H4TCPB-CH3 ligand and ZrCl4. Based on NKM-508, N,O coordination sites are constructed through aspartic acid amino modification and salicylaldehyde Schiff base reaction, ultimately anchoring a Co single atom to obtain the NKM-508-Co catalyst. This catalyst exhibits good stability, can efficiently activate potassium persulfate (PMS) to generate reactive oxygen species, can rapidly degrade various azo dyes such as eosin Y, orange G, methylene blue, and rhodamine B, and demonstrates excellent recyclability.

This invention discloses a wet tissue surface adhesive material, its preparation method, and its application, relating to the field of biomedical materials technology. The wet tissue surface adhesive material comprises: (1) dopamine-modified methacryloyl hyaluronic acid (HAMA-DOPA); (2) Pluronic F127-diacrylate (F127DA); (3) aldehyde-modified polyether F127 (F127CHO); (4) oxidized methacryloyl hyaluronic acid (OHAMA); and (5) a photoinitiator for initiating a photopolymerization reaction of the methacryloyl groups and acrylate groups in the above components under visible light irradiation. The photoinitiator comprises at least one of: lithium phenyl (2,4,6-trimethylbenzoyl) phosphate or a photoinitiator composition, wherein the photoinitiator composition comprises: eosin Y at a concentration of 0.05 to 0.25 mmol / L; triethanolamine at a mass-volume ratio of 1.5% to 3%; and N-vinylcaprolactam at a mass-volume ratio of 1% to 2%. This invention enables rapid, strong, and safe tissue adhesion.
