Abstract
We investigate numerically and on the scaling level the adsorption of a\ncharged colloid on an oppositely charged flexible membrane. We show that the\nlong ranged character of the electrostatic interaction leads to a wrapping\nreentrance of the complex as the salt concentration is varied. The membrane\nwrapping depends on the size of the colloid and on the salt concentration and\nonly for intermediate salt concentration and colloid sizes we find full\nwrapping. From the scaling model we derive simple relations for the phase\nboundaries between the different states of the complex, which agree well with\nthe numerical minimization of the free energy.\n
