“…For the latter case, nanoparticles containing high-Z elements (e.g. Au [4] , I, Bi [5] , and rare earth elements [6] ) which are able to interact with and absorb ionizing radiation could be utilized to enhance the efficacy of radiation therapy (RT) [7] , while those with high optical absorbance in the near infrared (NIR) region may convert photon energy into heat to induce photothermal therapy (PTT) of tumors [1d, 8] . The combination of different therapeutic strategies using multifunctional nanomedicine may offer synergistic effects in cancer treatment, so as to effectively treat tumors with decreased therapeutic doses and thus reduced side effects [9] .…”

Multifunctional theranostic agents have become rather attractive to realize image-guided combination cancer therapy. Herein, we develop a novel method to synthesize Bi2Se3 nanosheets decorated with mono-dispersed FeSe2 nanoparticles (FeSe2/Bi2Se3) for tetra-modal image-guided combined photothermal & radiation tumor therapy. Interestingly, upon addition of Bi(NO3)3, pre-made FeSe2 nanoparticles via cation exchange would be gradually converted into Bi2Se3 nanosheets, on which remaining FeSe2 nanoparticles are decorated. The yielded FeSe2/Bi2Se3 composite-nanostructures were then modified with polyethylene glycol (PEG). Taking advantages of the high r2 relaxivity of FeSe2, the X-ray attenuation ability of Bi2Se3, the strong near-infrared (NIR) optical absorbance of the whole nanostructure, as well as the chelate-free radiolabeling of 64Cu on FeSe2/Bi2Se3-PEG, in vivo magnetic resonance (MR)/computer tomography (CT)/photoacoustic (PA)/position emission tomography (PET) multimodal imaging was carried out, revealing efficient tumor homing of FeSe2/Bi2Se3-PEG after intravenous injection. Utilizing the intrinsic physical properties of FeSe2/Bi2Se3-PEG, in vivo photothermal & radiation therapy to achieve synergistic tumor destruction was then realized, without causing obvious toxicity to the treated animals. Our work presents a unique method to synthesize composite-nanostructures with highly integrated functionalities, promising not only for nano-biomedicine, but also potentially for other different nanotechnology fields.

“…Interestingly, NPs were designed to serve as radiosensitization enhancers. [14][15][16] Heavy metal (with high-Z elements such as Au, Pt, Bi, Ta, Gd, and Lu 17,18 ) NPs as promising computed tomography (CT) contrast agents (CAs) could be used in radiosensitizing therapy because of their high X-ray photon capture cross-section and compton scattering effect. When X-rays interact with high-Z NPs, Auger electrons and photoelectrons are emitted, with diameters ranging from nanometers to several micrometers.…”

The inherent radioresistance and inaccuracy of localization of tumors weaken the clinical implementation effectiveness of radiotherapy. To overcome these limitations, hyaluronic acid-functionalized bismuth oxide nanoparticles (HA-Bi 2 O 3 NPs) were synthesized by one-pot hydrothermal method for target-specific computed tomography (CT) imaging and radiosensitization of tumor. After functionalization with hyaluronic acid, the Bi 2 O 3 NPs possessed favorable solubility in water and excellent biocompatibility and were uptaken specifically by cancer cells overexpressing CD44 receptors. The as-prepared HA-Bi 2 O 3 NPs exhibited high X-ray attenuation efficiency and ideal radiosensitivity via synergizing X-rays to induce cell apoptosis and arrest the cell cycle in a dose-dependent manner in vitro. Remarkably, these properties offered excellent performance in active-targeting CT imaging and enhancement of radiosensitivity for inhibition of tumor growth. These findings demonstrated that HA-Bi 2 O 3 NPs as theranostic agents exhibit great promise for CT imaging-guided radiotherapy in diagnosis and treatment of tumors.

“…It was considered that bismuth (Bi) is a biocompatible element with high atomic number (Z), which features with high X-ray attenuation for CT imaging and strong photoelectric absorbance of X-ray radiation for radiotherapy sensitization [150][151][152]. On this ground, Bi 2 S 3 nanoparticles-integrated MoS 2 nanosheets were recently fabricated for simultaneous RT sensitization and PTT enhancement [148].…”
