Surface-Modified Oxide Nanoparticles: Synthesis and Application

This review deals with one of the most important classes of nanomaterials — oxide nanoparticles. Preparative methods for the synthesis of nanooxides, their hydro- and organosols, and methods for the chemical surface modification of oxide nanoparticles are comprehensively reviewed. The high surface area of nanooxide particles and their relatively low porosity allows efficient modification of the surface to obtain highly selective sorbents, microheterogeneous catalysts, biocompatible magnetic and fluorescent labels, means of drug delivery or removal of harmful components from living systems, and objects of environmental monitoring.
