Functionalized Nanoparticles: Advanced Materials for Optoelectronics and Nanomedicine Applications

Author(s): Ilaria Fratoddi

Functionalized nanoparticles depict a suitable platform for the development of efficient multi-functional responsive systems. A wide range of advanced applications are based on the use of metal nanoparticles (MNPs) or polymeric nanoparticles (PNPs), because of their unique chemical and physical properties and versatile synthesis, that allows to obtain functionalized surfaces with neutral or charged, hydrophilic or hydrophobic, organic or organometallic molecules. In particular, the research in biomedicine, catalysis, energy conversion and sensors are strongly influenced by these materials. The aim of this talk is to introduce the chemistry of functionalized nanoparticles with different surface functionalities. In particular, the growth of MNPs and PNPs, obtained by wet chemical methods will be presented together with spectroscopic and structural studies. These systems are particularly suitable for drug delivery applications, thanks to their cytocompatibility and easy preparation of bioconjugates with different drugs. Their chemical versatility offer the opportunity to have electronic conjugation that can be used in optical and electronic applications, such as chemical sensors.
