We describe the apparently first reversible unbinding transition of fluid
phosphatidylcholine bilayers. It is induced by minute concentrations of
in aqueous 0.1
solution. Mutual adhesion sets in at a
threshold of 
. The adhesion energy increases steeply with
concentration up to 
. It continues to rise
with a much smaller slope until the transition becomes irreversible at ca.
