by a zwitterionic N-oxide surfactant is proposed
as the core of a pH-responsive artificial gland model. The viscosity
and pH variations, induced by pulse additions of acid and base, are
investigated by a pyridinium salt and alizarin red S, respectively.
The artificial gland model is implemented by enclosing the gel within
a dialysis membrane, and its secretory action is tested by monitoring
the release of a fluorescent acridinium salt.
