Patent number: 6565789Abstract: Hydrophobic polymer surfaces whose level of protein binding is less than about 50-80 ng/cm2 are achieved by: (1) applying a coating solution composed of a solvent and a non-ionic surfactant having a HLB number of less than 5 to the surface; and (2) drying the surface to remove the solvent and thereby bring the surfactant into direct contact with the hydrophobic polymer. The combination of a low HLB number and the drying step have been found to produce low binding surfaces which can withstand multiple washes with water and/or protein-containing solutions. Alternatively, the low binding surfaces can be produced by applying the non-ionic surfactant to the mold surfaces which contact molten polymer and form the polymer into a desired shape, e.g., into a multi-well plate, a pipette tip, or the like. Further, the low binding surfaces may be produced by incorporating non-soluble, non-ionic surfactants having an HLB number of less than or equal to 10 into a polymer blend prior to molding the article.Type: GrantFiled: February 18, 2000Date of Patent: May 20, 2003Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Edward John Fewkes, Jr., James Arthur Griffin, Frances M.

Patent number: 6312656Abstract: The present invention is directed to a method for making silica. A liquid, preferably halide-free, silicon-containing compound capable of being converted by thermal oxidative decomposition to SiO2 is provided and introduced directly into the flame of a combustion burner, which converts the compound to silica, thereby forming finely divided amorphous soot. The soot is vaporized at the site where the liquid is converted into silica by pneumatically atomizing the liquid with a stream of oxygen gas, or a mixture of oxygen gas and nitrogen gas. The amorphous soot is deposited on a receptor surface where, either substantially simultaneously with or subsequently to its deposition, the soot is consolidated into a body of fused silica glass.Type: GrantFiled: July 30, 1997Date of Patent: November 6, 2001Assignee: Corning IncorporatedInventors: Jeffery Lynn Blackwell, Xiaodong Fu, Daniel Warren Hawtof, Dale Robert Powers

Patent number: 6301934Abstract: The invention is a method of making an optical fiber or cane (600) that has optical properties that vary axially. Core glass (100) and clad glass (200) are fed into a furnace to form the cane or fiber. The velocities of the feeding of the clad and core are controlled so that the total combined mass per unit time is constant. The diameter of the core (604) varies along the length of the fiber or cane in accordance with the control of the velocities. The variance in the core diameter results in the variance of the axial optical properties of the fiber or cane.Type: GrantFiled: August 13, 1998Date of Patent: October 16, 2001Assignee: Corning IncorporatedInventor: Michael S. Dobbins
