MOA 是一种用于石英晶体微天平 (QCMB) 测量的金电极表面修饰 SAM。可作为单层细胞，促进细胞摄取过量铁的金电极上铁蛋白的吸收。也可用于近红外辐射下巨噬细胞光热疗法一氧化氮纳米金 (NO-AuNPs) 的制备。该化合物可用于产生亲水性SAM。所产生的羧酸封端单层膜可以进一步官能化，从而引入更复杂的端基。也可用于形成保护屏障单层，以便沉积钝化氧化层。MOA可形成SAM，后者可用于金电极的表面改性，金电极对研究铁蛋白的表面特性很有用。也可用于形成SAM，将亲水性末端基团用作电极保护涂层，用于在半导体器件中有效传输电子。

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.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.MOA is a used as a SAM for surface modification of gold electrodes for quartz crystal microbalance (QCMB) measurement. It may be used as a monolayer that facilitates ferritin absorption on gold electrodes for uptake of excess iron in the cell. It may also be used for preparation of nitric oxide based gold nanoparticles (NO-AuNPs) for macrophage photo-thermal therapy under NIR irradiation.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. 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.This compound is used to produce hydrophilic SAMs. The resulting monolayers which are terminated with carboxylic acids can be further functionalized to introduce more complex end groups. Can also be used to form a protective barrier monolayer to allow deposition of a passivating oxide layer.
