Nanoparticle Assembled Hollow Spheres


技术优势

The new UC technology provides the following benefits:   Simple and easy to prepare ("one-pot synthesis"); General method to produce organic-inorganic hybrid materials; Achieves different structures of hybrid materials that have desirable encapsulation properties; Organics from hybrid spheres can be removed easily to produce hollow spheres; Operates at low temperatures. Nanoparticle Self-Assembly of Hierarchically Ordered Microcapsule Structures "    R. K. Rana, V. S. Murthy, J. Yu, M. S. Wong,    Advanced Materials 2005


技术应用

This new UC invention has several applications in "nanocapsule" technology, such as:   Drug delivery; Chemical storage and contaminated waste removal; Gene therapy; catalysis; cosmetics; magnetic contrast agents (for use in magnetic resonance imaging) and magnetooptoelectronics.


详细技术说明

Scientists at the University of California have developed a novel approach in which nanoparticles can arrange to form hollow sphere and other complex microstructures using particular block copolypeptides as the structure-directing agent. This improved method eliminates hydrolysis and condensation reactions that occur when producing hollow spheres from tetraethylorthosilicate (TEOS) while focusing on the directed assembly properties of these block copolypeptides.
