纳米粒子（NPs）的疏水性是决定纳米粒子在各种环境和生物条件下的团聚状态的重要物理化学性质。它在确定纳米颗粒的毒性以及环境、健康和安全影响方面发挥着主导作用。然而，迄今为止，还没有一种公认的标准方法来表征纳米粒子的疏水性。在这里，我们开发了一种用于测定纳米颗粒疏水性的相对染料吸附方法。该方法是对传统染料分配方法的改进，传统染料分配方法使用疏水性染料孟加拉红 (RB) 或亲水性染料尼罗蓝 (NB)。通过研究 RB 和 NB 的分配商，相对染料吸附方法消除了通过估计分散在液相中的纳米粒子的表面积而引入的不确定性。通过与最大颗粒分散法测定的纳米粒子的疏水性进行比较，我们证明了该方法的适用性和准确性。结论是相对染料吸附法可以作为比 RB 或 NB 分配更可靠的技术来确定 NP 的疏水性。
The hydrophobicity of nanoparticles (NPs) is a crucial physicochemical property that determines the agglomeration state of NPs under various environmental and biological conditions. It plays a predominant role in determining the toxicity and environmental, health, and safety impact of NPs. However, to date, there is not yet a well-accepted standard method for characterizing the hydrophobicity of NPs. Here, we developed a relative dye adsorption method for determining the hydrophobicity of NPs. This method is modified from the traditional dye partitioning method that uses either the hydrophobic dye, rose bengal (RB), or the hydrophilic dye, Nile blue (NB). By studying the partitioning quotient for both RB and NB, the relative dye adsorption method eliminates the uncertainty introduced by estimating the surface area of NPs dispersed in liquid phases. We have demonstrated the applicability and accuracy of this method by comparing them to the hydrophobicity of NPs determined with the maximum particle dispersion method. It is concluded that the relative dye adsorption method can be used as a more reliable technique than RB or NB partitioning for determining the hydrophobicity of NPs.
