Development of the microcapsules for Drug Delivery Systems by Shock Waves

Abstract

This paper describes the developments of microcapsules for Drug Delivery Systems (DDS) by using shock waves. The microcapsules are produced by dropping micro-droplets of Sodium Alginate with Polyvinyl Alcohol into Calcium Chloride. The concentration of Polyvinyl Alcohol is controlled to investigate the material and mechanical properties of produced microcapsule. A small quantity Liquid is injected into the produced micro-capsules for the measurements of the elasticity. Sodium Alginate hardens the micro-capsules, and Polyvinyl Alcohol softens them.
