Forces between nitrogen-containing self-assembled monolayers (SAMs) and zirconia particles in aqueous solutions

An atomic force microscope was used to measure the interaction forces between siloxane-anchored organic self-assembled monolayers (SAMs) with nitrogen-containing surface groups on silicon and micron-sized zirconia spheres in aqueous electrolyte solutions. The surface groups studied were alkylammonium salt and amines (primary, secondary, and tertiary). The pH of the solutions ranged from 2.5 to 9 (controlled by adding NaOH or HCl), and their ionic strength was held constant at 0.022 m (by adding NaCl). The results indicated that the alkylammonium salt surface exhibits a standard Debye double layer, whereas all of the amine surfaces exhibited a Stern layer, i.e. a charge inversion layer. The observed interactions were similar for SAMs formed from surfactants of two different alkyl chain lengths (11 and 16). The corresponding electrostatic interactions comprise the dominant part of the DLVO interactions under the conditions studied. The observed forces were consistent with film deposition results: vanadia films, but not titania films, form on alkylammonium salt surfaces; whereas both titania and vanadia films deposit on amine surfaces.

PROCESS FOR THE STEPWISE SYNTHESIS OF SILAHYDROCARBONS

The invention relates to a process for the stepwise synthesis of silahydrocarbons bearing up to four different organyl substituents at the silicon atom, wherein the process includes at least one step a) of producing a bifunctional hydridochlorosilane by a redistribution reaction, selective chlorination of hydridosilanes with an ether/HCI reagent, or by selective chlorination of hydridosilanes with SiCI4, at least one step b) of submitting a bifunctional hydridochloromonosilane to a hydrosilylation reaction, at least one step c) of hydrogenation of a chloromonosilane, and a step d) in which a silahydrocarbon compound is obtained in a hydrosilylation reaction.

Maleimido-terminated self-assembled monolayers

Four approaches have been explored for the preparation of maleimido-functionalized self-assembled monolayers (SAMs) on silicon. SAMs prepared by self-assembly of maleimido-functionalized alkyltrichlorosilanes (11-maleimido-undecyl-trichlorosilane) on oxide-covered silicon yield higher signals from maleimido functionalities in ATR-IR (attenuated total reflection IR) spectroscopy and XPS (X-ray photoelectron spectroscopy) than the other three methods. The surface composition of maleimido groups was tailored further by the formation of mixed monolayers with nonfunctionalized alkyltrichlorosilanes (decyltrichlorosilane). The order of the alkyl chains within the monolayers only slightly depends on the composition of the mixed monolayers. We utilized the maleimido-terminated SAMs to bind various nucleophilic compounds, alkylamines, alkylthiols, and thiol-tagged DNA oligonucleotides by means of conjugate addition.

Thiol functionalization of surfaces for biosensor development

The immobilization of biomolecules on substrate surfaces for biosensor development requires linking molecules that must meet a specific set of criteria. Two such agents based on bifunctional alkyltrichlorosilane structures, 1-bromo-11-(trichlorosilyl)-undecane and 1-(thiotrifluoroacetato)-11-(trichlorosilyl)-undecane, are employed to generate thiol-functionalized surfaces either by nucleophilic substitution followed by reduction (bromine-containing derivative) or deprotection (fluorine-containing compound). Both molecules have been attached to the surfaces of silicon wafers in conjunction with the diluent silane, octyltrichlorosilane. X-ray photoelectron spectroscopic analysis in the conventional and angle-resolved modes confirms that both silanization reactions were successful. The alkyl-bromine surfaces were subjected to treatment with a set of nucleophilic reactants followed by reduction and derivatization with trifluoroacetic anhydride. The latter in conjunction with surface analysis was used to estimate the level of thiol functionalization achieved. The fluorine-containing undecane surface has been studied by surface analysis both before and after deprotection of the thiol group by hydroxylamine solution. The results indicate that a high coverage of the surface was found for the protected moiety, with approximately 10% of the trifluoro acetate groups remaining after the deprotection procedure.
