Materials and methods for effective in vivo delivery of DNA nanostructures to atherosclerotic plaques

摘要

Provided are DNA-coated nanoparticles (DNA-NPS), superparamagnetic nanoparticles (DNA-SPNs), and superparamagnetic iron oxide nanopa rticles (DNA-SPIONs) as efficient imaging agents for targeting and imaging atherosclerotic lesions and treating atherosclerotic disease. The DNA-NS, DNA-SPNs, and DNA-SPIONs can enter macrophage cells via the Class A scavenger receptor (SR-A)-mediated pathways and can be used to specifically target atheroscleortic plaques.
