Disclosed is a preparation method for charge reversal and reversibly crosslinked redox-sensitive nanomicelles, falling within the technical field of biomedical materials. The method comprises: synthesizing thiocinamide from lipoic acid and ethylenediamine under an N,N-carbonyl diimidazole catalyst; and polymerizing thiocinamide, polyethylene glycol diglycidyl ether and lysine through a nucleophilic addition mechanism to prepare a poly(lysine-co-polyethylene glycol diglycidyl ether-co-thiocinamide) terpolymer. The micelle is endowed with excellent anti-protein nonspecific adsorption and enhanced cell uptake property through a self-assembly and protonation/deprotonation action; and a disulfide bond in lipoyl may form a linear polydisulfide structure under the action of 1,4-dithiothreitol, so that a micelle core is crosslinked, and a crosslinked structure is destroyed in the cell under a redox condition, and controlled release of a drug can be achieved. The Nanomicelle of the present invention is expected to be a carrier of drugs for treating cancers.

The present invention relates to binder compositions with improved amine components, and a method of manufacturing a collection of matter bound by said binder compositions.

Disclosed are a poly dopamine film and a preparation method and application thereof. The polydopamine film is loaded with silver sulfadiazine, and the preparation method achieves in-situ synthesis of si sulfadiazine on a conventional polydopamine film by microwave irradiation. In the method, the sulfadiazine is not dissolved in conventional aqueous ammonia, which has the following advantages: firstly, preventing the polydopamine film from being corroded by the aqueous ammonia; secondly, protecting mucosa such as eyes and nasal cavities of workers from stimulation and corrosion of the aqueous ammonia; and thirdly, avoiding the environmental problem caused by pungent odor and fumes emitted from high-concentration aqueous ammonia. In the method, without using the catalyst trifluoromethanesulfonic acid or trifluoromethanesulfonic salt, not only is the loading of silver sulfadiazine increased, but also the safely performance can be further improved.

The present invention provides a method of producing dye-containing thermosetting resin particles, the method including: dispersing seed particles formed from a thermosetting resin in a dispersion medium; and polymerizing a monomer for thermosetting resin synthesis in the thus obtained dispersion in the presence of a dye and an acid catalyst. By the method of producing dye-containing thermosetting resin particles according to the present invention, dye-containing thermosetting resin particles whose particle size variation coefficient is small at, for example, 8% or less, can be produced without performing a post-treatment such as centrifugation. Therefore, when immunological observation is performed by a fluorescent labeling method using fluorescent dye-containing resin particles produced by the method of producing dye-containing thermosetting resin particles according to the present invention, a high bright spot detection accuracy can be attained.
