    Rich drug transportation ability of serum albumin protein has inspired scientists to obtain drug nanocarriers from albumin. In the literature, different methods have been developed to prepare albumin nanoparticles and their drug delivery properties have been studied. Here, this study aims to obtain albumin nanoparticles for a first time using ionic liquid (IL) included systems. Goal of this project is using imidazolium based ionic liquids (green solvent) to prepare albumin nanoparticles as alternative solvents for the commonly used organic solvents. The use of volatile, toxic and flammable organic solvents in the albumin nanoparticle production has various negative effects on both human health and environment. Ionic liquids as non-flammable, non-volatile and non-toxic solvent candidates have attracted considerable attention in recent years both in the literature and in industry. Their ability to solve different types of solutes, designability, special mixing ability with water in IL/water binary systems and environmentally friendly properties cause ILs to overtake traditional organic solvents. This thesis study proposed a novel and environmentally friendly microemulsionlike method for producing albumin nanoparticles in IL/water binary systems. Various experimental parameters such as pH effects, albumin concentrations, water amount, surfactant effects, glutaraldehyde effects, homogenizer effects, etc. were investigated to obtain uniform albumin nanoparticles. As a result, we achieved to synthesize uniformly distributed 200 nm average size albumin nanoparticles at pH 9.0 using 1.5% (w/w) of bovine serum albumin (BSA) in 1-butyl-3-methylimidazolium tetrafluoroborate using TX-100/n-butanol surfactant mixture.
