23 Jul Magnetic polysaccharide nanometer gel material preparation method
Abstract
The invention discloses a magnetic polysaccharide nanometer gel material and a preparation method thereof, and provides a targeting controlled release means for a cell growth factor based on magnetic force effect. According to the invention, magnetic ferriferrous oxide nano particles are embedded in polysaccharide nano gel, base pairing crosslinking of the nano gel can be realized, and the magnetic polysaccharide nanometer gel material with a stable structure can be obtained. In the invention, the cell growth factor enables targeting controlled release by applying magnetic force externally, and usage of a chemical cross-linking agent can be avoided, biological activity of the embedded medicine can be guaranteed, and material usage security can be obviously improved. The preparation method has the advantages of simple process, easy operation, low temperature, fast solidification speed and short processing period, and has the application value on medicine controlled release, tissue engineering and regenerative medicine.
