Polymeric microcapsules for synthetic applications.
For decades scientists have been working on closed systems for transportation, catalysis and protection, which are inspired by natural cells. Only recently polymer based systems have emerged for these systems, since they are more robust, give protection from the environment and give a more stable membrane. Various methods have been developed to prepare polymer based capsules. They can be made b...

متن کاملAlginic acid sodium hydrogel co-transplantation with Schwann cells for rat spinal cord repair
INTRODUCTION The aim of the study was investigating the influence of Schwann cells-alginic acid sodium hydrogel co-transplantation on a rat model of spinal cord injury. MATERIAL AND METHODS Sprague-Dawley (SD) rats were randomly assigned to 4 groups: control, injury, injury with Schwann cell transplantation, and injury with Schwann cells-alginic acid sodium hydrogel co-transplantation. Gelati...
متن کاملIonomeric Films of Alginic Acid
Transparent, flexible films could be made by casting aqueous solutions of alginic acid, but they dissolved in water. When films were made from a solution of alginic acid and multivalent ions, they were still water soluble. However, when alginic acid films were immersed in a solution of salts with multivalent ions, they dissolved in water much more slowly, if at all. Treatment with calcium and z...
متن کاملHierarchical Porous Interlocked Polymeric Microcapsules: Sulfonic Acid Functionalization as Acid Catalysts
Owing to their unique structural and surface properties, mesoporous microspheres are widely applied in the catalytic field. Generally, increasing the surface area of the specific active phase of the catalyst is a good method, which can achieve a higher catalytic activity through the fabrication of the corresponding catalytic microspheres with the smaller size and hollow structure. However, one ...
