Summary:Adhesion has significant impacts in life sciences, such as, cell adhesion, bacterial aggregation and drug delivery vesicles in micro-scale, and contact lens adhesion in macro-scale. In order to quantify adhesion, several classical models for solid adhesion were constructed and widely adopted by the scientific community over the past decades, such as the celebrated Johnson-Kendall-Roberts (JKR), Derjaguin-Muller-Toporov (DMT), and the Tabor-Muller-Maugisfs JKR-DMT transition models. However, nano-shells / particles, vesicles and biological cells are shells instead of solid spheres, rendering the classical models invalid. A new mechanics model is necessary for shell adhesion.
