  • Publication number: 20120111117
    Abstract: The present invention provides embodiments relating to novel methods for determining, monitoring or detecting particle size distribution of a medium. In a preferred embodiment, the method comprises comparing a measured ultrasound attenuation spectrum of the medium with a calculated attenuation spectrum, where the calculated attenuation spectrum is obtained by accounting for the scattering of ultrasound waves into the receiver. The methods of the present invention can be used to determine particle size distribution in a dense suspension of particles in the intermediate wavelength regime. In other aspects, methods of the present invention may also be used to monitor changes in particle size distribution, infer the shape of particles, provide feedback to a process involving a change in particle size, and determine the completion of a dissolution process.

  • Publication number: 20090311332
    Abstract: A method for synthesizing a mesoporous silica nanoparticle, a mesoporous silica nanoparticle, and applications thereof are provided. The method includes fractionating a mesoporous silica nanoparticle suspension to produce size-fractionated mesoporous silica nanoparticle. The method further includes etching the size-fractionated mesoporous silica nanoparticle to produce synthesized mesoporous silica nanoparticle having a hollow, porous morphology configured to receive one of a therapeutic agent and an imaging material. The etching includes differential etching of silica from areas of low polymeric density within the mesoporous silica nanoparticle and re-depositing of the silica in areas of higher polymeric density existing near the surface of the mesoporous silica nanoparticle. A target material is loaded into the synthesized mesoporous silica nanoparticle and a controlled released of the target material is provided by decreasing the physiological pH of the surface of the mesoporous silica nanoparticle.
