Table 1:

The total mass of DMPA+TNAP deposited onto the QCM surface and TNAP present in the LB films transferred from monolayers with different lipid:protein molar ratio, and the enzymatic activity for the respective compositions. The mass of TNAP was calculated by subtraction the mass of DMPA calculated from the minimum area of the corresponding π-A isotherms
