Patent number: 8283156Abstract: The present invention relates to a method and apparatus for detecting analytes in a medium, and more particularly the present invention relates to an assay based on light diffraction which appears or changes upon the binding of analytes to their specific receptors laid out in patterns on a substrate, which has high sensitivity due to the appropriate choice of such patterns. The present invention is based on the principle that the pattern of recognition elements, which gives rise to the diffraction of the incident light in a diffraction-based assay, can be chosen in such a way so as to facilitate detection, and to enhance the signal to be detected compared to known gratings such as parallel straight lines. In one aspect the substrate itself has a surface topography designed to enhance the diffraction pattern signals. In another aspect the substrate is a diffractive optic element having the analyte-specific receptors affixed to the optic element.Type: GrantFiled: October 28, 2010Date of Patent: October 9, 2012Assignee: Axela Inc.Inventors: Cynthia M. Goh, Richard Loo, Jane B. Goh, Richard McAloney

Patent number: 8257785Abstract: A method for producing a composite nanoparticle, including the steps of: changing the conformation of a dissolved polyelectrolyte polymer from a first extended conformation to a more compact conformation by changing a solution condition so that at least a portion of the polyelectrolyte polymer is associated with a precursor moiety to form a composite precursor moiety with a mean diameter in the range between about 1 nm and about 100 nm; and cross-linking the polyelectrolyte polymer of the composite precursor moiety to form a composite nanoparticle.Type: GrantFiled: June 17, 2011Date of Patent: September 4, 2012Assignee: Vive Crop Protection, Inc.Inventors: Cynthia M. Goh, Jose Amado Dinglasan, Jane B. Goh, Richard Loo, Darren Anderson
