Abstract

An intelligent nano-gel for medicine has a core-shell structure composed of temp-sensitive high-molecular polyose as core and pH-sensitive acrylic polymer as shell, and is prepared through adding acrylic acid or its derivative to the aqueous suspension of polyose nanoparticles, filling N2, deoxidizing, adding cross-linking agent and trigger, and reaction. It has high response speed to the variation of temp and pH value.

Description

1. Technical field

[0001] The invention relates to a medicinal polymer material and a preparation method thereof, in particular to a medicinal gel material and a preparation method thereof, in particular to a medicinal intelligent nano gel material and a preparation method thereof. 2. Background technology

[0002] Smart gel materials are a class of materials whose volume or pore size changes drastically in response to changes in the external environment such as temperature, pressure, pH, electric field, and magnetic field. Smart gel materials have important applications in the controlled release of drugs, the immobilization of active enzymes and cells, and the separation and purification of active biomacromolecules, and have become a research hotspot in the field of materials in recent years. Among them, the temperature-sensitive hydrogel represented by poly-N-isopropylacrylamide (PNIPAm) is the most in-depth study, and its lower critical solution temperature (LCST) is 32Β°C...
