The rapidly growing applicability of metal-containing engineered nanoparticles (MENPs) has made their environmental fate, biouptake, and transformation important research topics. However, considering the relatively low concentration of MENPs and the high concentration of background metals in the environment and in organisms, tracking the fate of MENPs in environment-related scenarios remains a challenge. Intrinsic labeling of MENPs with radioactive or stable isotopes is a useful tool for the highly sensitive and selective detection of MENPs in the environment and organisms, thus enabling tracing of their transformation, uptake, distribution, and clearance. In this review, we focus on radioactive/stable isotope labeling of MENPs for their environmental and biological tracing. We summarize the advantages of intrinsic radioactive/stable isotopes for MENP labeling and discuss the considerations in labeling isotope selection and preparation of labeled MENPs, as well as exposure routes and detection of labeled MENPs. In addition, current practice in the use of radioactive/stable isotope labeling of MENPs to study their environmental fate and bioaccumulation is reviewed. Future perspectives and potential applications are also discussed, including imaging techniques for radioactive- and stable-isotope-labeled MENPs, hyphenated multistable isotope tracers with speciation analysis, and isotope fractionation as a MENP tracer. It is expected that this critical review could provide the necessary background information to further advance the applications of isotope tracers to study the environmental fate and bioaccumulation of MENPs.

“…Chemical method is the most frequently applied method for the preparation of metallic nanoparticles. This method can be categorized into chemical reduction methods [ 29 , 30 ], electrochemical methods (electrolysis) [ 31 ], and radiochemical methods [ 32 , 33 ]. Among these, radiochemical methods offer great advantages over other methods and particularly provide a clean technique for synthesis of noble metal nanoparticles.…”

Recent Advances in Shape-Controlled Synthesis of Noble Metal Nanoparticles by Radiolysis Route

et al. 2016

This paper focuses on the recent advances on radiolysis-assisted shape-controlled synthesis of noble metal nanostructures. The techniques and protocols for producing desirable shapes of noble metal nanoparticles are discussed through introducing the critical parameters which can influence the nucleation and growth mechanisms. Nucleation rate plays a vital role on the crystallinity of seeds while growth rate of different seeds’ facets determines the final shape of resultant nanoparticles. Nucleation and growth rate both can be altered with factors such as absorbed dose, capping agents, and experimental environment condition to control the final shape. Remarkable physical and chemical properties of synthesized noble metal nanoparticles by controlled morphology have been systematically evaluated to fully explore their applications.

“…Surface modifications, e.g., using chelators for attaching radiolabels, should be avoided, especially for small NPs. Radiolabeling can be achieved either by diffusive introduction of radioactive isotopes (Hildebrand and Franke 2012), by using radioactive precursor material for NP synthesis (Cydzik et al 2012;Ichedef et al 2013;Laycock et al 2014), by activation of NPs (Abbas et al 2010(Abbas et al , 2013Cydzik et al 2012;Holzwarth et al 2012;Marmorato et al 2011;Simonelli et al 2011) or implantation of radionuclides using recoil phenomena (Holzwarth et al 2014).…”

Strategies for radiolabeling of commercial TiO2 nanopowder as a tool for sensitive nanoparticle detection in complex matrices

Detection and quantification of engineered nanoparticles (NPs) in complex environmental or biological media is a major challenge since NP concentrations are generally expected to be low compared to elemental background levels. This study presents three different options for radiolabeling of commercial titania NP (TiO 2 -NP, AEROXIDE Ò P25, Evonik Industries, mean diameter 21 nm) for particle detection, localization, and tracing under various experimental conditions. The radiolabeling procedures ensure stability and consistency of important particle properties such as size and morphology. With the presented radiolabeling methods, detection (and quantification) limits for TiO 2 -NPs in concentrations as low as 0.5 ng/L can be realized in complex systems without the necessity of intense sample purification or pretreatment.
