General description
3-mercaptopropyl trimethoxysilane (MPTMS) is commonly used in surface modification of silica nanoparticles by creating thiol group on the surface.
Application
(3-Mercaptopropyl)triethoxysilane (MPTS) can be used as a reagent to prepare thiol functionalized materials. Silica, SBA-15, alumina, starch, and graphene can be functionalized with MPTS and used in various applications.
MPTS functionalized SBA-15 probe is used to determine dissolved mercury in solution.
MPTS functionalized SBA-15 probe is used to determine dissolved mercury in solution.
