Rational structural design of aromatic Azo photoactive small molecules for biomedical applications

heteroaryl Azo derivatives, and highlight the latest biomedical application advances, including biological imaging and detection, drug delivery, photopharmacology, phototherapy, miscellanea photo responsive biomaterials and constructs, and control in chemical biology. Furthermore, we discuss clinical translation challenges and opportunities in this field, proposing innovative strategies to address critical issues. This review aims to substantially advance the burgeoning field of aromatic Azo photoactive small molecules for biomedical applications.
