    Unconventional Nuclides for Radiopharmaceuticals by Jason P. Holland, Matthew J. Williamson, Jason S. Lewis

    Published 2010-01-01
    “…Until recently, the majority of clinical and basic science research has focused on the development of 11 C-, 13 N-, 15 O-, and 18 F-radiopharmaceuticals for use with positron emission tomography (PET) and 99m Tc-labeled agents for use with single-photon emission computed tomography (SPECT). With the increased availability of small, low-energy cyclotrons and improvements in both cyclotron targetry and purification chemistries, the use of “nonstandard” radionuclides is becoming more prevalent. …”

    Near-infrared light triggered in situ release of CO for enhanced therapy of glioblastoma by Juan Ge, Miaomiao Zuo, Qirong Wang, Zhen Li

    Published 2023-02-01
    “…Results In this study, a therapeutic nanoplatform (UCNPs@Ce6/3HBQ@CM) with combination of PDT and CO therapy was constructed, in which a photoCORM and a photosensitizer were loaded onto the surface of upconversion nanoparticles (UCNPs) functioning as photon transducer. Benefitting from NIR excitation and multicolor emission of UCNPs, the penetration depth of excitation light is enhanced and meanwhile simultaneous generation of CO and ROS in tumor site can be achieved. …”
