Description

Application

• Application of copper (I) selective ligands for PET imaging of reactive oxygen species through metabolic trapping: Bathocuproinedisulfonic acid disodium salt is utilized in the synthesis of copper (I) selective ligands. These ligands are essential for PET imaging to detect reactive oxygen species, highlighting its role in advanced medical imaging and research. This application is pivotal in understanding cellular mechanisms and disease pathologies where oxidative stress is involved (Tada, Mizuno, Shibata, Yasui, Kuge, 2024).
