“…However, to get a sensitive enough signal, AgNPs need to be efficiently close to the electrode surface, in a method usually called voltammetry of immobilized particles. This has been exploited for the quantification and characterization of AgNPs from commercial products using SPEs [60]. Interestingly, the oxidation peak potential recorded from linear sweep voltammetry (LSV) could also be related to the diameter of the nanoparticles.…”

Innovative methods to achieve the user-friendly, quick, and highly sensitive detection of nanomaterials are urgently needed. Nanomaterials have increased importance in commercial products, and there are concerns about the potential risk that they entail for the environment. In addition, detection of nanomaterials can be a highly valuable tool in many applications, such as biosensing. Electrochemical methods using disposable, low-cost, printed electrodes provide excellent analytical performance for the detection of a wide set of nanomaterials. In this review, the foundations and latest advances of several electrochemical strategies for the detection of nanoparticles using cost-effective printed devices are introduced. These strategies will equip the experimentalist with an extensive toolbox for the detection of nanoparticles of different chemical nature and possible applications ranging from quality control to environmental analysis and biosensing.

“…These nanomaterials exhibit their intrinsic electronic properties and high surface-to-volume ratios and can be exploited for a number of applications like sensors, electronics, and especially for catalysis. 1,2 The syntheses of silver nanomaterials are more important due to their physical properties which can be tailored for a specic application by controlling their size, shape, morphology, orientation, composition and surrounding microenvironments. [3][4][5][6] A variety of desired nanostructures with different morphologies including monodispersed nanoparticles, [7][8][9] nanoprisms, 10 nanocubes, 11 nanowires, 12 nanospheres, 13 nanoleaves 14 and nanodisks 15 have been constructed.…”

“…Although most of the work with these techniques involves proofs-ofconcept with conventional electrodes configuration, disposable screen printed electrodes have been used by Cheng et al [197] and Cepriá et al [196], and applied to the analysis of seawater and consumer products, respectively. A flexible hybrid polydimethylsiloxane-polycarbonate microfluidic chip with integrated screen printed electrodes have also been fabricated and applied for the electrochemical detection of quantum dots [211].…”

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.
