Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cell membranes. This allows for selectivity and also reversibility—the binding can also be undone. Researchers first found this phenomenon using spheres or colloids, and published their research today in theProceedings of the National Academy of Sciences.
