NanoSight was founded in 2004 by Dr Bob Carr and John Knowles after Carr discovered a technology which allows particles so small they were below the normal optical microscope limit to be seen, sized and counted in less than a minute for a fraction of the cost of electron microscopes.

SiO2 nanoparticles dispersed in water can be prepared from ..

Poly(methyl methacrylate) was also used as a ZnO surface modifier by Hong []. Nanoparticles of zinc oxide with a diameter of approximately 30 nm were synthesized by means of homogeneous precipitation followed by calcination. In order to introduce reactive groups onto the ZnO surface, a reaction was carried out between the hydroxyl groups and a silane coupling agent (3-methacryloxypropyltrimethoxysilane). Graft polymerization was effected by means of a reaction between the ZnO, containing silanol groups, and the monomer. Tests showed that the polymerization does not alter the crystalline structure of the ZnO nanoparticles. Their dispersion in the organic solvent can greatly improve the graft polymerization of PMMA, and further improvement can be achieved by the addition of other surfactants. Modification of ZnO nanoparticles by grafted PMMA increases the degree of lyophilicity of the inorganic surface and reduces the formation of aggregates. The work of Hong , showed that ZnO nanoparticles grafted with PMMA can increase the thermal stability of polystyrene.

Tang [] modified zinc oxide using poly(methacrylic acid) (PMAA). The hydroxyl groups on the ZnO surface reacted with the carboxyl groups of the PMAA, producing a complex of poly(zinc methacrylate) on the surface of the zinc oxide. Interpreting the particle size distributions, it was found that the ZnO modified with PMAA contains particles with smaller diameter ( 70 nm) compared with unmodified ZnO ( 300 nm). Analysis of the dispersive stability of the ZnO showed that the modified particles of zinc oxide dispersed better in water than unmodified particles. Conventional inorganic nanoparticles have hydroxyl groups (-OH) on their surface, due to the effect of humidity and the environment and type of precipitation. These groups react with COO- groups to form small complexes of poly(zinc methacrylate) on the surface of the zinc oxide. Analysis using the FTIR, TGA, TEM and XRD techniques confirms the presence of polymer molecules on the zinc oxide surface.

Silica Nanoparticles: Preparation, Properties and Uses

On the basis of the high biocompatibility and long blood circulation half-life of albumin, many studies have been devoted to the development of albumin-stabilized nanoparticles for biomedical applications [-]. Albumin could be introduced during nanoparticle synthesis or stabilizer replacement [-].
