  • Patent number: 9925515
    Abstract: A chromatographic stationary phase or solid phase extraction (SPE) sorbent are sol-gel metal oxide particles comprising metal oxide network units with organic functionality bonded to the metal of the metal oxide and possess a higher performance or capacity than that of conventional ligand coated silica particles. The organic functionality is distributed throughout the metal oxide particle and wherein the mole percent of metals of the metal oxides with bonded organic functionality is in excess of nine mole percent of the particle. The particles are prepared from sol-gel processing employing an acid catalyst or an acid catalyst followed by a base catalyst to metal oxide precursors, at least nine mole percent of which have organic functionality. The particles are processed from a sol-gel condensation product into a size depending on the intended use.

  • Patent number: 8607989
    Abstract: A filter and a method of forming a suture structure. The filter includes layered structure(s) interior to the filter. Each layered structure includes a carbon structure comprising carbon and a coating on a surface of the carbon structure. Each layered structure may further include a heparin layer that includes heparin and is on the coating. The coating of the filter includes cellulose, PMMA, PEMA, or PHEMA. The carbon structure may include an activated charcoal layer or carbon nanotube(s). The layered structure is configured to remove a contaminant flowing through the filter. The method of forming the suture structure includes forming a film on a suture that has been previously formed on a mammal. The film includes both a coating on the suture and a heparin layer that includes heparin and is on the coating. The coating of the suture structure includes cellulose, PMMA, PEMA, or PHEMA.
