Abstract
Novel nanoparticles-entrapping spherical composites, composed of a metal oxide or semi-metal oxide and a hydrophobic polymer, are disclosed. The spherical composites are characterized by well-defined spherical shape, a narrow size distribution and high compatibility with various types of nanoparticles. Further disclosed are processes for preparing the nanoparticles-entrapping spherical composites and uses thereof.
