Interaction of nanoparticles and biological fluids

Abstract

Recent studies have shown that the behavior of nanoparticles in in vivo conditions is not solely dependant on their physical properties, such are size and shape. The surface of nanoparticles in biological fluids interacts with biomolecules such are proteins, adsorbs these molecules, and leads to formation of nanoparticle-biomoelcular complex known as “protein corona”. This protein corona changes the properties of nanoparticles and their behavior in vivo. In this work three types of nanomaterial based on Hap and polymers were incubated in rats plasma, and the identification and quantification of proteins in protein corona that had formed around these nanoparticles, was done by means of electrophoresis and mass spectrophotometery.
