Le nanotecnologie sono tecnologie trasversali e abilitanti che costituiscono un modo radicalmente nuovo di realizzare materiali, prodotti e dispositivi con caratteristiche estremamente migliorate o del tutto nuove. Nella breve presentazione saranno illustrate le potenzialità del laboratorio in termini di supporto allo sviluppo di prodotti e di processi anche mediante alcuni casi reali di collaborazione con aziende.
