Photoactivation of Anticancer Ru Complexes in Deep Tissue: How Deep Can We Go?
Activation of anticancer therapeutics such as ruthenium (Ru) complexes is currently a topic of intense investigation. The success of phototherapy relies on photoactivation of therapeutics after the light passes through skin and tissue. In this paper, the photoactivation of anticancer Ru complexes wi...
