  • TRIOXYETHYLENE GOLD NANOCLUSTERS FUNCTIONALIZED WITH A SINGLE DNA
    Publication number: 20090269853
    Abstract: A method of making a nanoclusters functionalized with a single DNA strand comprising the steps of providing nanoclusters, combining said nanoclusters with thiolated DNA, incubating said nanoclusters and thiolated DNA mixture, combining said mixture with a solution comprising ethanol and dichloromethane; separating said mixture into an aqueous phase and an organic phase, mixing said aqueous phase with a solution comprising dicholormethane and NaCl, and separating the mixture into an aqueous phase and an organic phase; wherein said organic phase comprises said nanoclusters functionalized with a single DNA strand. Further, provided is a nanocluster functionalized with a single DNA strand comprising a nanocluster, said nanocluster being functionalized with a single DNA strand, said DNA strand having a length of about 10 to about 50 bases.

  • Thiol terminated monodisperse ethylene oxide oligomer capped gold nanoclusters
    Patent number: 7404928
    Abstract: A thiol terminated ethylene oxide oligomer and the method of substituting the oligomer onto a gold nanocluster surface using a thiol-exchange reaction to form a charge-neutral, non-ionizable, water soluble, ethylene oxide protected gold nanocluster. The thiol terminated ethylene oxide oligomer has the formula CH3(OCH2CH2)xSH where x varies from one to ten. Also disclosed is the related method of making the thiol terminated ethylene oxide oligomer.

  • Fluoroalkyl carbinol generating silane surface treatment agents
    Publication number: 20080087197
    Abstract: The compound is a silane surface treatment agent and is useful for modifying the surfaces of silicon oxide and other metal oxides with hexafluorodimethyl carbinol functional groups. Additionally provided is a surface treatment procedure that effectively bonds it and other alkoxysilanes via homogeneous and heterogeneous amine catalysis onto metal oxide surfaces.
