Description

General description

Butyltrichlorosilane (BTS) is a silane based surface modifier that forms a self-assembled monolayer(SAM) by forming a thin outer layer coated on the surface of a variety of metals and metal oxides.

Application

BTS can be coated on the glass substrate to introduce the surface alkyl, which can bind well with 2-methacryloyloxyethyl-4-azidobenzoate (MPAz) to convert hydrophophobic glass surfaces to superhydrophilic surfaces. It can functionalize zinc peroxide nanoparticle/polystyrene sulfonate (PSS) hybrid based sensors to improve the limit of detection by three-folds.
