An Ultrasound ‐Responsive Theranostic Cyclodextrin‐Loaded Nanoparticle for Multimodal Imaging and Therapy for Atherosclerosis

This study reports CD delivery via air-trapped polybutylcyanoacrylate nanoparticles (with diameters of 388  ± 34 nm) loaded with CD (CDNPs). The multimodal contrast ability of these nanoparticles after being loaded with IR780 dye in mice is demonstrated using ultrasound and near-infrared imaging. It is shown that CDNPs enhance the cellular uptake of CD in murine cells. In an ApoE–/– mouse model of atherosclerosis, treatment with CDNPs significantly improves the anti-atherosclerotic efficacy of CD. Ultrasound triggering further improves CD uptake, highlighting that CDNPs can be used for ultrasound imaging and ultrasound-responsive CD delivery. Thus, CDNPs represent a theranostic nanocarrier for potential application in patients with atherosclerosis.
