Problems solved by technology

Due to technical limitations at that time, the academic circle only used the adsorption of the outer surface, and did not make full use of the inner surface area and interlayer protection of layered materials. Therefore, it did not attract more attention and application from the scientific community.

Embodiment 1

[0034] 1. Stripping and reorganization of HP materials

[0035] The microscopic layers of HP materials are combined by weak electrostatic force or van der Waals force. When molecules or ions are introduced between the layers, the interlayer distance (interlayer domain) will increase; when it increases to a certain extent, the distance between layers The interaction force gradually weakens until finally disappears, resulting in the existence of the layered material in the solution in a monolithic state, and this process is called exfoliation of the layered material. Then, through the electrostatic attraction between the biomolecules and the sheet structure unit, the interface assembly is carried out to achieve the recombination with the introduced biomolecules. The driving force for recombination after stripping is the electrostatic attraction between biomolecules and sheet structural units, and the positive and negative charges carried by them can be regulated by the pH of the...

Abstract

The invention discloses a preparation method of a biologic and natural nanoscale inorganic carrier material. The preparation method comprises a supramolecular assembly chemical modification technology process on the basis of the micronization and vapor activation process. The preparation method is characterized in that a natural and environmentally-friendly substrate naming HP (Highporperty) material provided meets the ideal conditions of a carrier in the immobilization technology and also has the advantages that (1) an unique natural one-dimensional nanoparticle material and a nanoscale layered / chained microstructure are provided; (2) thirteen of the fourteen trace life elements represented by iodine, selenium, zinc and iron are enriched; (3) three performances, namely, inertia, acid / alkali resistance and resistance to high temperature (1,300 DEG C), are realized. The preparation method has the advantages that the micronizing and purifying, acidic-thermal-mechanical chemical activating, supramolecular assembly chemical modifying and other technical processes are carried out by the hydrodynamic flexible depolymerizing, dispersing, separating and purifying technical process, and thus a high-purity and micro-nano biomolecule immobilization carrier (support) material can be prepared.

Description

technical field [0001] The invention relates to a preparation method of biological natural nano-scale inorganic carrier (support) material which implements immobilization technology and application of biomolecules such as enzymes, cells, subcells and microorganisms. Background technique [0002] Immobilization of biological technology (immobilization of biological technology) is an emerging technology in the field of modern bioengineering. It is an important means for the wider and more effective use of organisms such as immobilized enzymes or immobilized cells. Chemical technology is a core technology in modern biotechnology and its industrialization. Among them, with the development of immobilization technology, the demand for carriers for immobilized biomolecules is becoming more and more urgent, and the development of new carriers is becoming more and more important, and the research is extremely active. [0003] As the supporting carrier of biomolecules, inorganic laye...
