Lipoprotein particles (LPPs) are biological nanoparticles whose physiological roles are greatly influenced by their sizes. The four major classes of LP are: very low density lipoprotein, intermediate density lipoprotein, low density lipoprotein (LDL) and high density lipoprotein. Since the predominance of small, dense LDLs is associated with increased risk of coronary artery disease (CAD) and diabetes mellitus, LPP profiling can be used to predict metabolic risk factors. Highly tunable LPP mimics can be synthesized using nanoparticles to carefully control for size, lipid composition and surface charge to facilitate the study LPPs in CAD. Here, we engineered LPP mimics using gold nanoparticles between 10-50 nm in diameters. We measured the mobility and zeta potential of these LPP mimics and showed that each mimics have distinct electrokinetic properties and are electrostatically stable.
