Improved functional imaging using enzyme-responsive nanoplatforms
In this opinion piece, Yuyu Yao (Southeast University Medical School, Jiangsu, China) and Zhen Cheng (Stanford University School of Medicine, CA, USA) discuss the potential use of enzyme-responsive nanoplatforms to help improve functional imaging in the context of abdominal aortic aneurysms (AAAs). Abdominal aortic aneurysms (AAAs) are characterized by aortic dilation and wall thinning [1]. High matrix metalloproteinase (MMP) activity and inflammation are associated with aneurysm rupture and may predict poor prognosis [2]. Fortunately, AAAs can be treated when diagnosed early. Currently, aneurysm diameter – a diameter greater than 5.5cm – is the main indication for surgical intervention for AAAs....
