  • Patent number: 10442932
    Abstract: Novel, nano-structured particles are formed by introducing a selected solid of interest into a structured fluid matrix formed by a dispersion of a small molecule host vessel components, such as a native or modified polysaccharide, cavitand, simple sugar, simple polyol or other similarly structured molecule known to be useful as a host vessel, in an acidic medium or other solvent, whereby the particle size of the introduced solid is reduced and or limited in the structured fluid matrix, by incorporation into or attachment to, the host vessel. The simple, one-step mixing process results in stabilized colloidal dispersions of the nanoparticles useful in a wide variety of applications.
    Type: Grant
