 The results of this study suggest that there is no correlation between in vivo residents and in vitro measurements, such as water resistance or adhesion. Furthermore, the surface energy of the lacquer films was not predictive of in vivo residents. Instead, a suitable model for the nail plate was found in high-density polyethylene sheet, which was used in further experiments.
