Patent number: 8580533Abstract: The present invention provides methods for enhancing chemical reactions of molecules, e.g., biomolecules, with destructible surfactants. The chemical reactions may involve and/or be associate with analysis, e.g., solubilizing, separating, purifying and/or characterizing the molecules. In one aspect, the anionic surfactants of the present invention may be selectively broken up at relatively low pH. The resulting breakdown products of the surfactants may be removed from the molecule/sample with relative ease. The invention has applicability in a variety of analytical techniques.Type: GrantFiled: May 30, 2003Date of Patent: November 12, 2013Assignee: Waters Technologies CorporationInventors: Edouard S. P. Bouvier, Bruce J. Compton, John C. Gebler, Martin Gilar, Ying-Qing Yu, Peter Jeng-Jong Lee, Elizabeth K. Brown

Patent number: 7294831Abstract: A MALDI sample plate 1 is disclosed which comprises a metallic substrate 2 having a circular groove or moat 3. A hydrophobic polytetrafluoroethylene layer 4 is applied to the substrate 2 and a central portion 5 of the substrate 2 is laser etched which roughens the surface of the substrate 2. A thin polystyrene layer is then applied to the polytetrafluoroethylene layer 4 and the central portion 5.Type: GrantFiled: August 3, 2005Date of Patent: November 13, 2007Assignee: Micromass UK LimitedInventors: Jeff Brown, Dominic Gostick, Edouard S.

Publication number: 20060189059Abstract: A plurality of N-doped strip portions are formed alternating with a plurality of P-doped regions. When a voltage is applied to the N-doped strip portions, a capacitance is created between the N-doped strip portions and the P-doped strip portions. A capacitance is also created between the N-doped strip portions and the underlying epitaxial silicon layer. A larger interface area between N-doped and P-doped regions generally increases the capacitance. By providing the N-doped strip portions, as opposed to a continuous N-doped region, the combined interface area between the N-doped strip portions and the underlying epitaxial silicon layer is reduced. However, more interface area is provided between the N-doped strip portions and the P-doped strip portions. A circuit simulation indicates that junction capacitance per unit peripheral length is 0.41 fF/?m, while the junction capacitance per unit area is 0.19 fF/?mˆ2.Type: ApplicationFiled: February 23, 2005Publication date: August 24, 2006Inventors: Jung Kang, Peter Jeng, Michael DeSmith, Md Hossain, Yi-feng Liu
