The “stickiness" of “dirty molecular velcro” is sufficient to bind selective objects but is weak enough to permit their two-dimensional diffusion.

Model of Nuclear Pore Complex transport selectivity

Video imaging by high-speed atomic force microscopy captures the molecular motions of a nuclear pore complex at work.
