Diagnosis application of bioactive glasses. A) Schematic illustration of the structure of UCNP@SiO2@MBG NPs. B) The luminescence in vivo imaging of athymic nude mice with intravenous injections of UCNPs@SiO2@MBG. Resolution/sensitivity of in vivo imaging enhanced by incorporating Ca (top row of in vivo imaging combined with Ca). All images were obtained under the same instrumental conditions (powder density ≈ 120 mW cm−2 on mice's surfaces). C) The loading capacity range of UCNPs@SiO2@MBG/ZnPc. D) MBG/UCNP nanocomposites' intensity versus release of ZnPc. E) Linear range of I/I o response for each release percentage. UCNPs: upconversion nanoparticles; ZnPc: zinc phthalocyanine.
