    【摘要】动脉粥样硬化是一种常见的血管疾病，其特征是脂质的沉积及发生相关的炎性反应。动脉粥样硬化易损斑块是急性心血管事件的主要病理原因。因此，易损斑块的早期发现和及时干预治疗具有重要的临床意义。尽管临床上已开发出多种针对易损斑块的诊疗方法，但其导致的急性临床事件仍居高不下，而纳米颗粒在这方面表现出了巨大的潜力。纳米颗粒在影像学中应用广泛，因其独特的光学特性，可以高效标记组织和细胞以检测疾病状态；金属纳米颗粒能实现高分辨率成像；还可用作药物递送载体，提高治疗效果。文章回顾了纳米颗粒用于动脉粥样硬化易损斑块靶向诊断的研究进展，探讨纳米颗粒在相关领域的未来发展以及向临床转化的挑战与机遇。

    【Abstract】Atherosclerosis is a common vascular disease， which is characterized by lipid deposition and related inflammatory reactions. Vulnerable atherosclerotic plaque is the main pathological cause of acute cardiovascular events. Therefore， early detection and timely interventional treatment of vulnerable plaques are of clinical significance. Although a variety of clinical methods have been developed for the diagnosis and treatment of vulnerable plaques ......
