DescriptionReferencesS.D.SStructural FormulaProduct DescriptionPhosphonic acid derivatives are used for surface modification on oxidized metals such as Al2O31), TiO22), ZrO23), SiO24), Mica5), stainless(SS316L) 6), nitinol7), hydroxyapatite8), AgO9), ZnO10), ITO11,12).For a long time, organosilanes have been used to form self assembled monolayer (SAM) on the metal oxide. However, it is not always adaptable in the applications due to the poor stability and polymerization of the reagent with each other. On the other hand, phosphonic acid derivatives equally form a SAM on the metal oxide despite being very stable compounds. Also, phosphonic acid derivatives have been reported to use formation of more stable and dense SAM than organosilanes. Klauk et. al. and Sekitani et. al. show alkyl phosphonate SAM on Al2O3 is more useful than the trichlorosilane derivatives SAM as an conductor film of an organic transistor13).Sharma et. al. have reported the work function of ITO substrate increases by the oxygen plasma treatment or modifying ITO substrate with phosphonic acid (FOPA) containing perfluoroalkyl group. However, the increased level of work function maintains with FOPA modified substrate for 246 hours, while the work function immediately decreases with the substrate treated by oxygen plasma11). In addition, the organic thin-film solar cell fabricated using the modified TO with FOPA increase the stability of light intensity, the driving voltage, and life time.There are three perfluoro based phosphonic acids available with different alkyl lengths.1) T.

Dojindo细胞分析
细胞活力和细胞毒性测定用于药物筛选和化学物质的细胞毒性测试。Dojindo开发了高度水溶性的四唑盐，称为WST。WST-8是高度稳定的WST，用于Cell Counting Kit-8（CCK-8）。由于WST-8甲maz是水溶性的，因此不会形成晶体。因此，不需要诸如MTT测定的增溶过程。此外，CCK-8的检测灵敏度高于其他四唑盐，例如MTT，XTT，MTS或WST-1。
