A review on natural polymer-based microsphere

Microspheres having free flowing powder characteristics, which are consisting of synthetic polymers and proteins. These biodegradable in nature particle size less than 200um. the multiparticulate drug delivery systems from natural material. received much attention not only for prolonged release, but also targeting anticancer drugs. In future by combining various other strategies, microspheres will find central place novel delivery, particularly diseased cell sorting, diagnostics, gene & genetic materials, safe, targeted effective vivo supplements as miniature versions organ tissues body.
