对于含有带电或可电离分子的二元自组装膜(m-SAM NPs)包裹的纳米颗粒(m-SAM NPs)，可以直接用相反电荷的纳米颗粒标准滴定这些NPs，直到沉淀到总的电中性点，从而获得m-SAM组分的相对平衡常数和自由吸收能差。
For nanoparticles coated with binary SAMs (m-SAM NPs) containing charged or ionizable molecules, the relative equilibrium constants and the difference in the free energies of absorption of the m-SAM's components can be obtained in a straightforward way by titrating such NPs with oppositely charged nanoparticle "standards" until precipitation at the point of overall electroneutrality.
