Dojindo,FOPA/100/F329,膦酸衍生物同样在金属氧化物上形成SAM

Product Description

膦酸衍生物用于氧化金属的表面改性,如 Al2O31)、TiO22)、ZrO23)、SiO24)、Mica5)、不锈钢(SS316L)6)、镍钛诺7)、羟基磷灰石8)、AgO9)、ZnO10)、ITO11、12 ). 长期以来,有机硅烷一直被用于在金属氧化物上形成自组装单层 (SAM)。然而,由于试剂之间的稳定性和聚合性差,在应用中并不总是适用。另一方面,膦酸衍生物同样在金属氧化物上形成SAM,尽管它们是非常稳定的化合物。此外,据报道,膦酸衍生物使用形成比有机硅烷更稳定和致密的 SAM。克劳克等。人。和 Sekitani 等。人。显示 Al2O3 上的烷基膦酸酯 SAM 比三氯硅烷衍生物 SAM 作为有机晶体管的导体膜更有用13)。Sharma 等。人。已经报道了通过氧等离子体处理或用含有全氟烷基的膦酸(FOPA)修饰ITO衬底来增加ITO衬底的功函数。然而,提高的功函数水平在 FOPA 改性衬底上保持 246 小时,而在氧等离子体处理的衬底上功函数立即降低 11)。此外,使用具有 FOPA 的改性 TO 制造的有机薄膜太阳能电池提高了光强度、驱动电压和寿命的稳定性。有三种不同烷基长度的全氟膦酸可供选择。

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。
