Title: Controlled microwave assisted synthesis of functionalized silica nanoparticles

Abstract

A method of synthesizing silica nanoparticles. The method includes hydrolyzing a silica precursor to form a plurality of monomers, each monomer of the plurality comprising a microwave reactive silicon species. The plurality of monomers is irradiated by an energy source configured to generate microwave frequency energy. Irradiation cases the plurality of monomers polymerize into a silica nanoparticle.

Magnetic agglomeration method for size control in the synthesis of magnetic nanoparticles

Patent Huber, Dale L [Albuquerque, NM]

A method for controlling the size of chemically synthesized magnetic nanoparticles that employs magnetic interaction between particles to control particle size and does not rely on conventional kinetic control of the reaction to control particle size. The particles are caused to reversibly agglomerate and precipitate from solution; the size at which this occurs can be well controlled to provide a very narrow particle size distribution. The size of particles is controllable by the size of the surfactant employed in the process; controlling the size of the surfactant allows magnetic control of the agglomeration and precipitation processes.
