    摘要: Fluorescent phenyl xanthene dyes are described that comprise any fluorescein, rhodamine or rhodol comprising a particular C9 phenyl ring. One or both of the ortho groups on the lower C9 phenyl ring is ortho substituted with a group selected from alkyl, heteroalkyl, alkoxy, halo, haloalkyl, amino, mercapto, alkylthio, cyano, isocyano, cyanato, mercaptocyanato, nitroso, nitro, azido, sulfeno, sulfinyl, and sulfino. In one embodiment, halo and/or hydroxy groups are used. Optimal dyes contain a lower C9 phenyl ring in which both ortho groups are the same and the lower ring exhibits some form a symmetry relative to an imaginary axis running from the phenyl rings point of attachment to the remainder of the xanthene dye through a point para to the point of attachment. The phenyl xanthene dyes may be activated. Furthermore, the phenyl xanthene dyes may be conjugated to one or more substances including other dyes. The phenyl xanthene dyes are useful for a number of purposes, including labels for use in automated DNA sequencing as well the formation of fluorescent “bar codes” for polymeric particles used in the multiplexed analysis of analytes.

    摘要: A method of manufacturing a sensor, the method including forming an array of chemically-sensitive field effect transistors (chemFETs), depositing a dielectric layer over the chemFETs in the array, depositing a protective layer over the dielectric layer, etching the dielectric layer and the protective layer to form cavities corresponding to sensing surfaces of the chemFETs, and removing the protective layer. The method further includes, etching the dielectric layer and the protective layer together to form cavities corresponding to sensing surfaces of the chemFETs. The protective layer is at least one of a polymer, photoresist material, noble metal, copper oxide, and zinc oxide. The protective protective layer is removed using at least one of sodium hydroxide, organic solvent, aqua regia, ammonium carbonate, hydrochloric acid, acetic acid, and phosphoric acid.
