RT Journal Article SR Electronic T1 Advances in Reactive Oxygen Species (ROS) Imaging JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP jnumed.120.245415 DO 10.2967/jnumed.120.245415 A1 Niren Murthy A1 Eli Misael Espinoza A1 Joachim Justad Roeise A1 I-Che Li A1 Riddha Das YR 2020 UL http://jnm.snmjournals.org/content/early/2020/12/31/jnumed.120.245415.abstract AB Reactive oxygen species (ROS) play a pivotal role in many cellular processes and can either be beneficial or harmful. Design of ROS sensitive fluorophores has allowed for imaging of specific activity and has helped elucidate mechanisms of action for ROS. Understanding the oxidative role of ROS in the many roles it plays allows us to understand the human body. This review provides a concise overview of modern advances in the field of ROS imaging. Indeed, much has been learned about the role of ROS throughout the years, however it has recently been shown that using nanoparticles, rather than individual small organic fluorophores, for ROS imaging can further our understanding of ROS.
