    • To be more precise, the infection of cells by animal viruses takes place most commonly along the endocytic pathway. (There are some cases in which the virion instead fuses with the membrane.) For plant or fungal cells-although they are eukaryotes-the mechanisms are quite different due to the profoundly different nature of the cell membrane. Moreover, bacterial cells are infected by viruses (called "phages") that almost always inject their genome into the cytoplasm rather than entering as a whole.

    • 8 found that the initial adhesion process occurs within a few milliseconds (and it can be expected to proceed even more rapidly for smaller colloids). On such short time scales, permeation of water cannot significantly alter the volume of the vesicle, and it may thus be considered as constant. We will make the same assumption in our own model. One should bear in mind, though, that on longer time scales the increased pressure inside the vesicle can relax, thereby lowering the membrane tension and influencing the degree of wrapping.

    • As we have mentioned, there is a second source of tension, which originates from the fact that reducing the excess area of a fluctuating membrane also reduces its entropy. See, for instance: David, F.; Leibler, S. J. Phys. II Fr. 1991, 1, 959. However, we will disregard this contribution in the present work.

    • note
    • If at some point the mean curvature is zero but the surface is not flat, the Gaussian curvature is negative, so the local environment is a saddle point. The only contribution to the bending energy then comes from the second term in eq 7, which in this sense measures the energy cost of a saddle-like deformation. Note, however, that it also contributes to the energy at points that are not saddle-points.
