Aortic aneurysms are bulges in the aorta, the largest blood vessel in the body, and can be caused by factors such as smoking, high blood pressure, diabetes, or injury. Currently, there is no treatment for aortic aneurysms, and surgery is the only option once the aneurysm reaches a certain size. However, researchers at Lehigh University are working on developing minimally invasive ways to regenerate and repair the elastic fibers in blood vessels using nanoparticles. These nanoparticles can deliver regenerative therapeutics directly to the affected tissue, potentially slowing, reversing, or even stopping the growth of aneurysms. The researchers have also found that rod-shaped nanoparticles with a high aspect ratio are more effective at penetrating the endothelial cell barrier and reaching the affected tissue. The ultimate goal of this research is to develop a nonsurgical regenerative therapy that can slow or even regress the growth of aortic aneurysms. [Extracted from the article]
