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.

The purpose of this study was to devise a novel electrochemical immunosensor for ultrasensitive detection of alfa-fetoprotein based on Fe(3)O(4)/Au nanoparticles as a carrier using a multienzyme amplification strategy. Greatly enhanced sensitivity was achieved using bioconjugates containing horseradish peroxidase (HRP)

Nanoparticle based chemical sensor arrays with four types of organo-functionalized gold nanoparticles (AuNPs) were introduced to classify 35 different teas, including black teas, green teas, and herbal teas. Integrated sensor arrays were made using microfabrication methods including photolithography and lift-off
