Abstract
There is an instructive and simple way to reconcile different measures of van der Waals attraction between phospholipid bilayers. Surface fo rce apparatus (SFA) measurements, qualitatively larger than osmotic st ress (OS) and pipet aspiration (PA) results, probably include a domina ting contribution from the mica on which bilayers are mounted in the S FA.
