Abstract

Statement of Purpose: Gold nanoparticles (AuNP) are of considerable interest as CT contrast agents. AuNP have favorable characteristics for this application such as strong X-ray attenuation, excellent biocompatibility, and tunable sizes and shapes. However, there have been conflicting reports on the role of gold nanoparticle size on their performance as contrast agents for CT, despite the fact that physics indicates that there should be no effect of AuNP size. Therefore, we herein sought to test the hypothesis that AuNP size would not affect AuNP CT contrast properties. On the other hand, pharmacokinetics and biodistribution may vary significantly as AuNP size changes, and will impact their potential utility as CT imaging contrast agents. We therefore sought to understand the role of size on pharmacokinetics and biodistribution via in vivo studies of AuNP ranging in size from 4 to 79 nm.
