TABLE 2.

Results obtained from the non-linear fittings performed to the average permeated protein per skin area ($\mu g_{protein}/m{m}_{skin}^2$) as a function of permeation time, for both plain mixtures of human insulin and ionic liquids and for the biofilms integrating ionic liquid (choline geranate 1:2) and loaded (or not) with human insulin.
