“…Using spICP-MS, the rate at which the diameter decreases can also be correlated to an increase in dissolved signal, allowing a mass balance to be calculated to ensure an accurate depiction of Ag NP transformation [112]. These dissolution processes have also been demonstrated in natural systems where Ag NPs were dosed into a littoral lake mesocosm [133]. This capability is also important for monitoring transformation of nanomaterials in consumer products.…”

From its early beginnings in characterizing aerosol particles to its recent applications for investigating natural waters and waste streams, single particle inductively coupled plasma-mass spectrometry (spICP-MS) has proven to be a powerful technique for the detection and characterization of aqueous dispersions of metal-containing nanomaterials. Combining the high-throughput of an ensemble technique with the specificity of a single particle counting technique and the elemental specificity of ICP-MS, spICP-MS is capable of rapidly providing researchers with information pertaining to size, size distribution, particle number concentration, and major elemental composition with minimal sample perturbation. Recently, advances in data acquisition, signal processing, and the implementation of alternative mass analyzers (e.g., time-of-flight) has resulted in a wider breadth of particle analyses and made significant progress toward overcoming many of the challenges in the quantitative analysis of nanoparticles. This review provides an overview of spICP-MS development from a niche technique to application for routine analysis, a discussion of the key issues for quantitative analysis, and examples of its further advancement for analysis of increasingly complex environmental and biological samples.

“…Furtado et al [50] investigate the persistence and transformation of silver nanoparticles in a littoral lake mesocosm Although this review focuses on ENMs, natural nanoparticles cannot be forgotten because natural nanoparticles of different or similar composition are going to be found mixed with ENPs, as in the case of environmental samples [218,219]. This means that the identification of ENPs in the presence of natural ones involves an additional challenge.…”

“…1 nm) are available. Thus free ionic species can be easily isolated from nanoparticles, whereas the separation of the corresponding complexes can be difficult depending on the molecular weight of the complexes and the size of the NPs [49,50]. Moreover, depending on their composition and surface functionality, ENMs and the corresponding dissolved species can show interactions with the membrane surfaces, affecting their recoveries [51].…”

“…SP-ICP-MS in combination with alkaline or enzymatic digestions has proven to provide reliable information about size distributions and number concentrations in laboratory studies involving food matrices spiked with silver or gold nanoparticles [32, 38, 40, 41], in tissues from organisms exposed to nanoparticles [33,37,42,124], and native nanoparticles in foods and consumer products [95]. SP-ICP-MS has also been applied to study the fate of silver nanoparticles in in vitro human digestion [104], lake mesocosms [50] and washing solutions from commercial detergents [90], to track their dissolution [127] and agglomeration [128] in natural waters or their release from food additives [129].

The increasing demand of analytical information related to inorganic engineered nanomaterials requires the adaptation of existing techniques and methods, or the development of new ones.The challenge for the analytical sciences has been to consider the nanoparticles as a new sort of analytes, involving both chemical (composition, mass and number concentration) and physical information (e.g. size, shape, aggregation). Moreover, information about the species derived from the nanoparticles themselves and their transformations must also be supplied. Whereas techniques commonly used for nanoparticle characterization, such as light scattering techniques, show serious limitations when applied to complex samples, other well-established techniques, like electron microscopy and atomic spectrometry, can provide useful information in most cases. Furthermore, separation techniques, including flow field flow fractionation, capillary electrophoresis and hydrodynamic chromatography, are moving to the nano domain, mostly hyphenated to inductively coupled plasma mass spectrometry as element specific detector.Emerging techniques based on the detection of single nanoparticles by using ICP-MS, but also coulometry, are in their way to gain a position. Chemical sensors selective to nanoparticles are in their early stages, but they are very promising considering their portability and simplicity.Although the field is in continuous evolution, at this moment it is moving from proofs-of-2 concept in simple matrices to methods dealing with matrices of higher complexity and relevant analyte concentrations. To achieve this goal, sample preparation methods are essential to manage such complex situations. Apart from size fractionation methods, matrix digestion, extraction and concentration methods capable of preserving the nature of the nanoparticles are being developed. This review presents and discusses the state-of-the-art analytical techniques and sample preparation methods suitable for dealing with complex samples. Single-and multimethod approaches applied to solve the nanometrological challenges posed by a variety of stakeholders are also presented.

“…[16,17] The paper by Furtado et al [18] has succeeded in analysing silver nanoparticles under the near natural conditions of a lake mesocosm using SP-ICPMS (along with other confirmatory techniques). Another solution examined by several researchers has been the coupling of field flow fractionation [18][19][20] or hydrodynamic chromatography [21] with ICPMS in order to reduce some of the problems associated with matrix effects. The paper by Proulx and Wilkinson couples HDC with SP-ICPMS in order to detect nAg in a spiked natural river water sample.…”
