“…The application of spICP-MS as a possible means to characterize these materials was first proposed by McCarthy and Degueldre, who cite the prior aerosol literature as well as a personal communication with B. Wernli [21]. This led a decade later to a series of key papers by Degueldre et al [1,[22][23][24][25] that established the basic methodology of the spICP-MS technique as we know it now. It was some years between the publication of these papers and the renewed interest in spICP-MS as a stand-alone method for characterizing NPs [26] and as a powerful means to further characterize size fractionated NPs [27].…”

“…Considerations for the application of single particle ICP-MS for routine nanomaterial analysis Works of Kawaguchi [11], and of Degueldre [1,[22][23][24], demonstrated the feasibility of using ICP-MS for the analysis of colloids, but more work was needed to develop a technique that could provide additional meaningful information about the particles analyzed. In order to characterize and quantify unknown particles samples, several aspects of signal acquisition, data processing, and calibration must be addressed.…”

Single Particle ICP-MS: Advances toward routine analysis of nanomaterials

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.

“…[158] A number of reports on the use of ICP for the characterization of colloidal systems can be found in literature. While some reports describe the elemental analysis of synthetic, inorganic particles, [161][162][163][164] most of the literature reported for ICP characterization of colloids deals with slurry methods for the analysis of sediments for environmental sciences. [155][156][157] Investigations on polymer-based hybrid nanoparticles are rare in literature.…”

This thesis focuses on the controlled assembly of monodisperse polymer colloids into ordered two-dimensional arrangements. These assemblies, commonly referred to as colloidal monolayers, are subsequently used as masks for the generation of arrays of complex metal nanostructures on solid substrates.The motivation of the research presented here is twofold. First, monolayer crystallization methods were developed to simplify the assembly of colloids and to produce more complex arrangements of colloids in a precise way. Second, various approaches to colloidal lithography are designed with the aim to include novel features or functions to arrays of metal nanostructures.The air/water interface was exploited for the crystallization of colloidal monolayer architectures as it combines a two-dimensional confinement with a high lateral mobility of the colloids that is beneficial for the creation of high long range order. A direct assembly of colloids is presented that provides a cheap, fast and conceptually simple methodology for the preparation of ordered colloidal monolayers. The produced two-dimensional crystals can be transformed into nonclose-packed architectures by a plasma-induced size reduction step, thus providing valuable masks for more sophisticated lithographic processes. Finally, the controlled co-assembly of binary colloidal crystals with defined stoichiometries on a Langmuir trough is introduced and characterized with respect to accessible configurations and size ratios.Several approaches to lithography are presented that aim at introducing different features to colloidal lithography. First, using metal-complex containing latex particles, the synthesis of which is described as well, symmetric arrays of metal nanoparticles can be created by controlled combustion of the organic material of the colloids. The process does not feature an inherent limit in nanoparticle size and is able to produce complex materials as will be demonstrated for FePt alloy particles. Precise control over both size and spacing of the particle array is presented.Second, two lithographic processes are introduced to create sophisticated nanoparticle dimer units consisting of two crescent shaped nanostructures in close proximity; essentially by using a single colloid as mask to generate two structures simultaneously. Strong coupling processes of the parental plasmon resonances of the two objects are observed that are accompanied by high near-field enhancements. A plasmon hybridization model is elaborated to explain all polarization dependent shifts of the resonance positions. Last, a technique to produce laterally patterned, ultra-flat substrates without surface topographies by embedding gold nanoparticles in a silicon dioxide matrix is applied to construct robust and re-usable sensing architectures and to introduce an approach for the nanoscale patterning of solid supported lipid bilayer membranes.

“…Moreover, both the particle size and particle number concentration can be measured simultaneously using spICP-MS. Details of the theory have been outlined in the literatures [69,70,[73][74][75]. Usually, the detection limit of spICP-MS is as low as mid ng/L, which is suitable for NP analysis in the environmental and biological samples [76,77].…”

Silver Nanoparticles in the Environment

View full text Add to dashboard Cite

The accurate analysis of silver nanoparticles (AgNPs) in complicated environmental and biological matrix is the premise for the assessment of AgNP risks. In the past few decades, a myriad of methods have been developed for the concentration and determination of AgNPs. In this chapter, methodologies for the separation, characterization, and quantification of AgNPs are introduced, and the advantages and shortcomings of each technique are also discussed. In most cases, multiple schemes are often needed to get comprehensive information of the analytes. To meet the ultra-trace detection of AgNPs in the environment, techniques with higher resolution and sensitivity are required.
