    摘要: Intermediates and methods for forming passivated surfaces on oxide layers and articles produced thereby are described. Hydroxyl or hydroxide groups on the oxide surfaces are reacted with a metal reagent of the formula Y(L-Pol)m, where Y is a transition metal, magnesium or aluminum, L is oxygen, sulfur, selenium or an amine, and “Pol” represents a passivating agent such as a polyethylene glycol, a hydrocarbon, or a fluorocarbon. The resulting modified surface can be further reacted with a passivating agent having a phosphate functional group or a polyvalent reagent comprising a passivating moiety and a plurality of functional groups that are reactive with or that form complexes with Y. The passivating agent can also include a functional group such as biotin to provide surfaces with a desired functionality. The passivated surfaces exhibit minimal binding to bio-molecules and can be used in single-molecule detection schemes.

    摘要: Intermediates and methods for forming activated metal complexes bound to surfaces on oxide layers, immobilizing beads to the modified surface and articles produced thereby are described. Hydroxyl groups on the oxide surfaces are reacted with a metal reagent complex of the formula Y(L-Pol)m, where Y is a transition metal, magnesium or aluminum, L is oxygen, sulfur, selenium or an amine, and “Pol” represents a passivating agent such as a methoxyethanol, a polyethylene glycol, a hydrocarbon, or a fluorocarbon. The resulting modified surface can be further reacted with a passivating agent having a phosphate functional group or a plurality of functional groups that are reactive with or that form complexes with Y. The metal oxide surfaces exhibit minimal binding to bio-molecules, exhibit uniform deposition and immobilization of beads at high density, can be subsequently modified to create surfaces having a variety of properties, and can be used for nucleic acid sequencing and other analyses and in single-molecule detection schemes.

    摘要: A system for detection of nucleic acids can include an excitation source configured to transmit excitation energy to a reaction site including a single molecule of nucleic acid reacted with a two-photon absorption moiety. The system also can include an optical system configured to focus the excitation energy transmitted from the excitation source to a focal region containing the reaction site, wherein said excitation energy within the focal region is sufficient to cause two-photon absorption by the two-photon absorption moiety. The system can further include a detector configured to detect emissions generated at the reaction site resulting from two-photon absorption of the excitation energy by the two-photon absorption moiety.
