Method for manufacturing silver sulfide hollow sphere modified by protein ribonuclease

Abstract

The invention discloses a method for manufacturing a silver sulfide hollow sphere modified by protein ribonuclease. The method provided by the invention comprises the following steps: firstly preparing chelate solution, using amino acid perssad of protein ribonuclease protein crystal to be combined with semiconductor metal ion in a cross-linking way, adding sulphur resources in the chelate solution, and taking a protein crystal cluster as a framework to manufacture a nanostructured hollow sphere by utilizing the combination of excess silver ions and sulphur ions in a reaction system to drive silver sulfide nano-particles to grow constantly and control the time of reaction and the concentration of reactant. The nanostructured hollow sphere provided by the invention has significant facilitation for multiple disciplines such as photoelectricity conversion, photochemical catalysis, drug sustained release, gene carrier and the like. According to the invention, the method is simple to operate, needs warm condition, has low cost and has no pollution; the synthesized silver sulfide nano hollow sphere has good water-solubility, stability and biocompatibility, so that the method is a simple method to manufacture a functional nano-material; and the manufactured nono-material has a special structure, so that the method provided by the invention has great market application value.

Description

technical field [0001] The invention relates to a method for preparing protein ribonuclease protein crystal-modified silver sulfide nano hollow spheres, belonging to functional materials and medical treatment materials. Background technique [0002] Semiconductor sulfide materials have been widely used in optical conductors, medical imaging, and solar cells due to their unique optical, electrical, and thermal properties. Although the preparation, size and shape control of semiconductor sulfides have always been the research difficulties, due to the incomparable nanoscale effects of nanomaterials compared with other material effects, such as larger specific surface area and larger stock displacement. The latest research shows that semiconductor quantum dots such as silver sulfide, copper sulfide and lead sulfide have good near-infrared absorption optical properties, and are an ideal material for biomedical imaging, as well as nano-semiconductor sulfide and titanium oxide.
