“…Thus, with the particle-size calibration method, any change in nebulized aerosol transport efficiency or absolute sensitivitieseither from a changing sample matrix or from driftwill result in an inaccurate mass quantification. To improve the accuracy of particle quantification, approaches based on internal standardization, , standard addition, isotope dilution, , and matrix-matched standards have been used. Here, we demonstrate the use of online microdroplet calibration − (Figure ) as an accurate calibration strategy for spICP-TOFMS that eliminates the need for exhaustive sample preparation and matrix removal procedures.…”

Single particle inductively coupled plasma time-offlight mass spectrometry (spICP-TOFMS) is a powerful analytical technique for quantifying elements in nanoparticles and microparticles; however, like most ICP-MS-based measurements, matrix effects can be a major challenge for accurate quantification in spICP-MS. Here, we report the use of online microdroplet calibration to overcome extreme matrix effects observed for the analysis of nanoparticles and microparticles in seawater. With online microdroplet calibration, particle-containing samples are introduced into the ICP along with monodisperse microdroplets containing known element mass amounts. The microdroplet standards, which experience the same plasma conditions as the analyte particles, are used to measure matrix-matched absolute element sensitivities. With online microdroplet calibration, one multielemental standard can be used to determine the element mass amounts in diverse types of analyte particles independent of the sample matrix. We evaluate the matrix tolerance of spICP-TOFMS with online microdroplet calibration through the analysis of metal nanoparticles, polystyrene microplastic beads doped with rare-earth elements, and metaloxide submicrometer particles in artificial seawater. Our results demonstrate mass recoveries of 98−90% for the analysis of individual gold NPs in ultrapure water to 99% seawater. In the analysis of food-grade TiO 2 submicron particles, accurate Ti-mass per particle is determined with matrix-caused signal attenuation up to 80% in a pure seawater matrix. We also demonstrate accurate diameter determinations of individual 3.4 μm polystyrene beads at concentrations of up to 80% simulated seawater. Furthermore, simultaneous and accurate quantification of rare-earth elements in the polystyrene beads is achieved.

“…Jiménez-Lamana et al [ 15 ] used cysteine to stabilize Ag(I) and Triton X-100 as a surfactant to stabilize AgNPs. The use of surfactants was reported in other studies [ 22 , 24 , 25 ] to prevent the loss of NPs and to recover the total spiked Ag. Gao et al [ 24 ] also studied the process of sample grinding and concluded that it improved NP extraction leading to recoveries of nearly 100% for gold nanoparticles in mice organs.…”

“…Generally, enzymatic extraction is conducted using proteinase K [ 26 ], but this enzyme can partially dissolve AgNPs, and the presence of matrix residues leads to a lower nanoparticle recovery [ 17 ]. Comparisons between alkaline and enzymatic extractions were reported [ 25 , 27 ], obtaining better results with the alkaline extraction. Sung et al [ 27 ] observed that TMAH gave higher recoveries (102%) than enzymatic extraction (74%) for the extraction of AgNP and AuNP from zebrafish liver samples.…”

Extractions methods based on ultrapure water, tetramethylammonium hydroxide (TMAH), and tetrasodium pyrophosphate (TSPP) were applied to faeces collected from two in vivo experiments of pigs and chickens fed with a silver-based nanomaterial to study the fate and speciation of silver. For TMAH extraction, cysteine and CaCl2 were used to evaluate their stabilization effect on the silver forms. The analytical techniques single-particle inductively coupled plasma mass spectrometry (SP-ICP-MS), hydrodynamic chromatography hyphenated to ICP-MS (HDC-ICP-MS) and asymmetric flow field flow fractionation coupled to ICP-MS (AF4-ICP-MS) were applied to the simultaneous detection of particulate and dissolved silver. Results have shown that water extraction was a suitable option to assess the environmental release of silver, with percentages of 3 and 9% for faeces of pigs and chickens, respectively. The use of TMAH extraction combined with SP-ICP-MS analysis was useful to characterize Ag-containing particles (less than 1%). Both stabilizers, cysteine and CaCl2, have a similar effect on silver nanoparticle preservation for chicken faeces, whereas cysteine-Triton was better for pig samples. In any case, silver extraction efficiency with TMAH was low (39–42%) for both types of faeces due to a matrix effect. TSPP followed by ICP-MS enabled the fractionation of the silver in the faeces, with silver sulphide (41%) and ionic silver (62%) being the most abundant fractions. Graphical Abstract

“…34 nm for lysates of green algal cells). 7 This can be overcome by application of hyphenated techniques, such as HPLC-ICP-MS, which enable detection of smaller particles (from ∼1 nm). The chromatographic separation of the nano and dissolved forms of silver was performed on a reversed-phase column (Nucleosil C 18 ) with relatively wide pore sizes (1000 Å and 4000 Å) [8][9][10] or amino column (Venusil Durashell-NH 2 ) with pore sizes of 500 Å and 1000 Å.…”
