**5. Conclusions**

We prepared essential oil-loaded nanocapsules with broad-spectrum antifungal activity. The obtained results sugges<sup>t</sup> the efficacy of nanoencapsulation for enhancing pure essential oil activity. These ecofriendly nanosytems could be a valid alternative to synthetic antifungals and could find effective applications in various industrial sectors concerning health, agri-food and the environment.
