Patent number: 9658206Abstract: A method for multiplex characterization of individual particles by their size, shape, mechanical properties (deformability), and chemical affinity to recognition agents. The analysis can be performed from concentrated solutions. The method detects transient sticking of particles in the pore and points to its location along a pore axis. If a pore is decorated with a recognition agent for an analyte present in a solution, it is possible to distinguish specific binding at the place of the recognition agent, and non-specific adsorption of the analyte. The method confirms whether any individual particle or hydrogel completely translocates the pore and allows unambiguous detection and characterization of multiple particles or hydrogels in the pore, which would previously corrupt the results, so that higher analyte concentrations can be used for faster analysis.Type: GrantFiled: May 9, 2014Date of Patent: May 23, 2017Assignee: The Regents of the University of CaliforniaInventors: Zuzanna S. Siwy, Kenneth J. Shea, Ken Healy, Laura Michele Innes, Matthew Schiel, Matthew Pevarnik

Publication number: 20100003204Abstract: The invention discloses and claims a new class of chemical compositions with ideal sunscreen properties. The chemical composition comprises spherical particles between 200 nm and 10 microns in diameter prepared by an emulsion polymerization of tetraalkoxysilanes or organotrialkoxysilanes or organobridged trialkoxysilanes with a dye monomer bearing two or more alkoxysilyl groups attached to the bridging chromophore. The resulting spheres absorb ultraviolet light. The dye can be any organic chromophore capable of receiving multiple trialkoxysilyl groups resulting in multipoint covalent attachment that precludes leaching of the dye from the spheres. The formic acid-toluene-monomer emulsion polymerization allows for large-scale (>100 gram) synthesis of monodisperse particles under acidic, non-aqueous conditions without surfactants. The particles less than 1 micron in diameter are smooth as talc to the touch and will provide a smooth formulation for sunscreen creams or lotions.Type: ApplicationFiled: July 2, 2009Publication date: January 7, 2010Applicant: Energy Materials CorporationInventors: Douglas Anson Loy, Kenneth J. Shea, Dylan J. Boday, Jason T. Wertz
