A QCM-D study gave a thickness of the wet [(PLL/PLGA).sub.3] film of 100 [+ or -] 10 [Angstrom] .
This is similar to what was seen in a QCM-D study of the same system .
Whereas the QCM-D measurements were performed at 32[degrees]C, which was intended to mimic the temperature of a typical wound, the ellipsometry experiments were performed at ambient temperature.
