Abstract

<p>Functional nanoparticles have been paid attention in various fields due to their specific properties such as transparency, and reactivity, quantum size effect. In this paper, present status and prospects of polymeric nanoparticles for drug delivery system and iron oxide nanoparticles for magnetic tapes are presented. First, polymeric nanoparticles prepared by a spherical crystallization method is reported. To understand the efficacy of polymeric nanoparticles to the biofilms, the interaction between bacteria and polymeric nanoparticles was revealed. Subsequently, cobalt ferrite nanoparticles prepared by solution chemistry method is reported. Different size and shape, magnetic properties of cobalt ferrite nanoparticles were studied according to the amount of surfactant. Finally, various electron microscopy methods which can be applied for characterization of functional nanoparticles are reported.</p>
