Graphical Abstract
Peripheral Vascular Interventions
In article number 2404251, Jin-young Kim, Hongsoo Choi, and co-workers investigate a quantum dot (QD) magnetic guidewire and system for non-fluoroscopic peripheral vascular interventions. By leveraging HgCdSe/HgS/CdS/CdZnS/ZnS/SiO2 core/multi-shell QD-embedded elastomeric composites with real-time short-wave infrared (SWIR) imaging and magnetic manipulation, the guidewire enables SWIR detection upon near-infrared excitation for X-ray-free imaging and can be precisely guided through complex blood vessels using an external magnetic field.
