Usage

General Description

11-Bromoundecyltrichlorosilane is a chemical compound that features a long linear carbon chain which is attached to a silicon atom with three chlorine attachments on one end, and a bromine atom on the other end. It is a type of organic silane, and it is typically employed in the realm of surface chemistry, primarily as a reagent to create thin monolayer films on surfaces using a process known as silanization. The product created, a silane film, provides modified surfaces with unique properties such as hydrophobicity, biocompatibility, and adhesive properties. It plays a significant role in industries such as biotechnology, microelectronics, and material science.

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.

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.
