Opis

Opis ogólny

8-Mercaptooctanoic acid (MOA) is an carboxylic acid terminated alkanethiol that forms self-assembled monolayers (SAMs) that facilitate subsequent surface immobilization of other molecular species.[1]

8-mercaptooctanoic acid (MOA) forms a self-assembled monolayer (SAM) on the surface of nanoparticles. MOA consists of thiol and carboxylic groups which helps in the surface treatment of different nanoparticles.[2][3]

Zastosowanie

MOA is a used as a SAM for surface modification of gold electrodes for quartz crystal microbalance (QCMB) measurement.[2] It may be used as a monolayer that facilitates ferritin absorption on gold electrodes for uptake of excess iron in the cell.[3] It may also be used for preparation of nitric oxide based gold nanoparticles (NO-AuNPs) for macrophage photo-thermal therapy under NIR irradiation.[4]

MOA may form SAM that can be used in the surface modification of gold electrodes which are useful for the study of surface characteristics of ferritin.[3] It may also be used to form SAM with hydrophilic end groups to be used as a protective coating on the electrodes for efficient electron transport in semiconductor devices.[5]

This compound is used to produce hydrophilic SAMs. The resulting monolayers which are terminated with carboxylic acids can be further functionalized[6] to introduce more complex end groups. Can also be used to form a protective barrier monolayer to allow deposition of a passivating oxide layer.[7]
