• 中文摘要： 本篇論文的主要目的在以理論分析一表面電位會自我調整的細胞體吸附至一球形收集器表面的變化行為。溶液中陽性電解質對其吸附行為的影響也列入理論模式中。理論分析結果發現,當細胞體與收集器之間的距離小於一特定值時,陽性電解質會增加其間的電荷排斥力,此增加的電荷排斥力同時也會降低細胞體的吸附速率。理論結果同時也顯示,Hamaker常數的值對於細胞體的吸附速率有非常顯著的影響,特別是在高電解質強度的溶液中。當溶液離子強度為定值時,Peclet常數值的增加和 Aspect ratio值的降低會具有增強細胞體吸附速率的作用。在一定值的Peclet常數, Aspect ratio和陽性電解質濃度控制之下,細胞體的吸附速率會隨著溶液離子強度的增加而增強。
• 英文摘要： The adhesion rate of cells under charge regulation onto a spherical collector with constant potential has been theoretically investigated in this paper. The effect of the presence of cationic electrolytes towards the suspension medium on adhesion rate was of particular focus. The result of numerical simulation reveals that the presence of cationic electrolytes in the suspension medium raises the electrostatic repulsion force between cell and collector surface, whenever the separation distance between them was smaller than a critical value. This has created the effect of decreasing the adhesion rate of cells. It is found that the adhesion rate of cells is quite sensitive towards the value of the Hamaker constant, especially at a high ionic strength value. For a fixed ionic strength, the adhesion rate of cells could be increased by either increasing the Peclet number or decreasing the aspect ratio. The adhesion rate increased with an increase of ionic strength for fixed values of Peclet number, aspect ratio and cationic concentration.
