Thrombin Activatable CT/NIRF Dual Imaging Probe Based on Gold Nanoparticles |
초록 |
Gold nanoparticles (AuNPs) are a unique material because of their controllable morphology, low cytotoxicity, surface plasma resonance effect and high X-ray absorption. For these reasons, AuNPs have attracted scientist’s attention that developed AuNPs as an imaging probe. In this study, we developed thrombin activatable CT/NIRF imaging probe which can detect thrombosis in the blood stream. The particles were coated with silica layer to have stability and biocompatibility in human body. Then thrombin activatable peptide conjugated dye (Thr-dye) was conjugated to the nanoparticle surface. When the probe interact with thrombin, which it is well known as serine protease, the enzyme cleaves the peptide and dequenches NIRF dye which makes detecting thrombosis possible. These feasibilities of biocompatible AuNPs as CT/NIRF dual imaging probe were showed promising results for detecting thrombosis. |
