“…These results compare favorably with our previous report, which applied gold nanoparticles as adsorbents for radioactive iodine [ 40 ]. In the previous study, approximately 1.6 mg of gold was necessary to prepare the desalination membrane filter [ 41 ]; the present method uses approximately 0.1 mg AgNPs to achieve high desalination performance. Because silver is much cheaper than gold, the proposed Ag-CAM is more practical for the treatment of radioactive iodine wastes.…”

Increasing concerns regarding the adverse effects of radioactive iodine waste have inspired the development of a highly efficient and sustainable desalination process for the treatment of radioactive iodine-contaminated water. Because of the high affinity of silver towards iodine species, silver nanoparticles immobilized on a cellulose acetate membrane (Ag-CAM) and biogenic silver nanoparticles containing the radiation-resistant bacterium Deinococcus radiodurans (Ag-DR) were developed and investigated for desalination performance in removing radioactive iodines from water. A simple filtration of radioactive iodine using Ag-CAM under continuous in-flow conditions (approximately 1.5 mL/s) provided an excellent removal efficiency (>99%) as well as iodide anion-selectivity. In the bioremediation study, the radioactive iodine was rapidly captured by Ag-DR in the presence of high concentration of competing anions in a short time. The results from both procedures can be visualized by using single-photon emission computed tomography (SPECT) scanning. This work presents a promising desalination method for the removal of radioactive iodine and a practical application model for remediating radioelement-contaminated waters.

“…For example, surface-modified iron oxide (Fe 3 O 4 ) nanoparticles have been applied to selectively adsorb toxic heavy metals such as Cr(III), Co(II), Ni(II), Cd(II), Pb(II), and As 3+ from aqueous media [ 108 ]. Furthermore, engineered Au nanomaterials have been developed that are excellent adsorbents for the desalination of non-radioactive and radioactive iodine anions [ 109 , 110 , 111 ]. However, there are still several problems in the practical application of these methods.…”

As concerns about the substantial effect of various hazardous toxic pollutants on the environment and public health are increasing, the development of effective and sustainable treatment methods is urgently needed. In particular, the remediation of toxic components such as radioactive waste, toxic heavy metals, and other harmful substances under extreme conditions is quite difficult due to their restricted accessibility. Thus, novel treatment methods for the removal of toxic pollutants using extremophilic microorganisms that can thrive under extreme conditions have been investigated during the past several decades. In this review, recent trends in bioremediation using extremophilic microorganisms and related approaches to develop them are reviewed, with relevant examples and perspectives.

“…There are several nonmetallic radionuclides adsorbed onto MNPs by this method, such as 18 F (Cao et al, 2015; Jauregui‐Osoro et al, 2011; Q. Liu et al, 2011; J. Zhou et al, 2011), 125 I (M. Chen, Guo, et al, 2018; Chrastina & Schnitzer, 2010; Clanton et al, 2018; Farrag et al, 2017; Shao et al, 2011; Zhu et al, 2015), and 211 At (Cedrowska et al, 2016; L. Dziawer et al, 2017; Ł. Dziawer et al, 2019; Kučka et al, 2006). These radionuclides are attached to the surface of MNPs based on the strong affinity between halogen and metal surface (M. H. Choi et al, 2016, 2017; Mushtaq et al, 2017). For instance, Au nanorods were radiolabeled with 125 I by leveraging the strong interaction of the radionuclide with AuNPs and its capability to replace citrate functionalization on the surface of AuNPs (Clanton et al, 2018).…”

Radiolabeled metal‐based nanoparticles (MNPs) have drawn considerable attention in the fields of nuclear medicine and molecular imaging, drug delivery, and radiation therapy, given the fact that they can be potentially used as diagnostic imaging and/or therapeutic agents, or even as theranostic combinations. Here, we present a systematic review on recent advances in the design and synthesis of MNPs with major focuses on their radiolabeling strategies and the determinants of their in vivo pharmacokinetics, and together how their intended applications would be impacted. For clarification, we categorize all reported radiolabeling strategies for MNPs into indirect and direct approaches. While indirect labeling simply refers to the use of bifunctional chelators or prosthetic groups conjugated to MNPs for post‐synthesis labeling with radionuclides, we found that many practical direct labeling methodologies have been developed to incorporate radionuclides into the MNP core without using extra reagents, including chemisorption, radiochemical doping, hadronic bombardment, encapsulation, and isotope or cation exchange. From the perspective of practical use, a few relevant examples are presented and discussed in terms of their pros and cons. We further reviewed the determinants of in vivo pharmacokinetic parameters of MNPs, including factors influencing their in vivo absorption, distribution, metabolism, and elimination, and discussed the challenges and opportunities in the development of radiolabeled MNPs for in vivo biomedical applications. Taken together, we believe the cumulative advancement summarized in this review would provide a general guidance in the field for design and synthesis of radiolabeled MNPs towards practical realization of their much desired theranostic capabilities.
