Microencapsulation and Controlled Release from Spherical Ceramic Particles Developed for Drug Delivery and Industrial Processes

摘要

An increasing range of applications, from the targeting of cancer tumors to protecting material surfaces against bacterial attack, require the production of delivery systems in particulate form. Although a range of organic materials are used to manufacture capsules and particles, only a limited number of inorganic controlled-release systems have been developed for industrial products. This is the case for ceramics, which despite a number of intrinsic advantages such as high mechanical strength, resistance to corrosion, thermal and electrical stability, bio-compatibility, and an environmentally benign nature have remained an untapped resource for the manufacture of controlled release systems.
