A Tailored Multifunctional Anticancer Nanodelivery System for Ruthenium‐Based Photosensitizers: Tumor Microenvironment Adaption and Remodeling

Ruthenium complexes are promising photosensitizers (PSs), but their clinical applications have many limitations. Here, a multifunctional nano‐platform PDA‐Pt‐CD@RuFc formed by platinum‐decorated and cyclodextrin ( CD )‐modified polydopamine ( PDA ) nanoparticles (NPs) loaded with a ferrocene‐appended ruthenium complex ( RuFc ) is reported. The NPs can successfully deliver RuFc to the tumor sites. The release of RuFc from the NPs can be triggered...
