We synthesize a novel prospective nanocomposite material for X-ray induced photodynamic therapy. ZnO:Ga core is coated by the SiO2 shell facilitating a functionalization by a photosensitizer, protoporphyrin PpIX layer. By steady-state and time resolv

Singlet oxygen is a highly reactive species which is involved in a number of processes, including photodynamic therapy of cancer. Its very weak near-infrared emission makes imaging of singlet oxygen in biological systems a long-term challenge. We add
