ABSTRACT
Liposomes and nanoparticles are currently among the most investigated technologies for drug delivery, diagnostic and treatment of diseases, and for food preservation, processing and optimization of nutritional properties. These nanodevices provide controlled release, improvement of kinetic and diffusion properties, and also vectorized delivery of loaded compounds. In general, in order to guarantee the safety for human or veterinarian use, liposomes and nanoparticles must not induce immunogenicity or toxicity. The aim of this chapter is to review the recent advances in the fields of liposomes and nanoparticles regarding their use in improving drugs and food features. Moreover, the directions that these nanotechnologies are taking in pharmaceutical and food sciences and markets are discussed.
