    <title language="eng">Development of Reference Materials for Determination of Nanoplastics in Aqueous Media</title>
    <abstract language="eng">A lack of harmonised terminology hinders accurate description of many nano-object properties. An overview on nanoscale reference materials for environmental , health and safety measurements has been provided by Stefaniak et al. Since then several nanoscale reference materials were produced as finely dispersed nanoparticles, including catalytic active silver nanoparticles and iron oxide nanocubes. Polymeric nanoparticles made of polypropylene (PP), polyethylene (PE) and poly(ethylene terephthalate) (PET) are ongoing reference materials projects. A first study on PP has shown that mechanical breakdown of macroscopic PP towards nano PP is possible. Hereby the nano PP is stabilized by a strongly negative zeta potential of – 44 mV. This provides a long-term stability of the nanoparticles at ambient conditions in cases of low ionic strength. Since this nano PP has no added colloidal stabilizers, we suggest this as a potential reference materials candidate for reliable determination PP nanoplastics. Moreover, the nano PP may function as a reference for the estimation of possible toxic effects of nanoplastics. Efforts in producing nano PP labeled with ultra-small gold nanoparticles are reported.</abstract>

    <title language="eng">SAXS for the determination of the size distribution of nanoparticles: Application in catalysis</title>
    <abstract language="eng">The open source software packages SASfit1 and McSAS2 are widely used to determine the size distribution of nanoparticles. SASfit is based on classical curve fitting. The type of size distribution needs to be provided as constraint for analysis. Very often the lognormal size distribution is useful as shown for the characterization of single- and multimodal magnetic iron oxide particles. The use of SASfit is part of efforts to standardize analyzing methods for magnetic nanoparticles within the EU project NanoMag (www.nanomag-project.eu). In contrast to SASfit, it is not necessary to provide the type of size distribution when using the program McSAS. Both programs provide tools that allow the user to estimate uncertainties of the derived size distributions. Such is helpful in the development of nanoscale reference materials for environmental, health and safety measurements. As an example, a detailed study on using SAXS in the characterization of ultra-small-silver nanoparticles is presented. These particles are useful in the catalytic reduction of 4-nitrophenol and display an adjustable activity (see Figure).&#13;

    <title language="eng">Self-healing materials: structure elucidation with SAXS</title>
    <abstract language="eng">Healable materials could play an important role in reducing the environmental footprint of our modern technological society through extending the life cycles of consumer products and constructions. Future technologies require smart materials with advanced properties including responsiveness to external stimuli and particularly the ability to autonomously repair inflicted damage. The introduction of reversible connections in the polymer architecture, either in a non-covalent fashion, such as in supramolecular polymers, or by using dynamic covalent chemistry. One facile approach involves the implementation of reversible polymer networks as they offer high mechanical strength and thermal properties that are readily modified by the nature of the connecting dynamic bonds and the crosslinking density. In this context, small-angle scattering allows a detailed insight into the network structure of self-healing polymers either in bulk materials or in form of hydrogels. Here we report on how small-angle scattering can contribute to reveal the network structure. A first example is the conditional repair by locally switching the thermal healing capability of dynamic covalent polymers with light.&#13;
 Typical experimental SAXS curves of a photo- and thermal switchable polymer are shown. The scattering pattern show three characteristics. Region 1 is dominated by a forward scattering interpreted as resultant from large scale inhomogeneities of the bulk polymers (characterized by a first correlation length). The second scattering contribution can be interpreted as resultant from the network and is characterized by its entanglement distance. The mesh size of this network can be described by a second correlation length. Region 3 of the scattering pattern is dominated by a broad peak. Taking all effects into account, we approximate the total scattering as a sum of the three scattering contributions. In particular, the Debye-Büche function is used for I1 the Ornstein-Zernike function for the crosslinking contribution I2 and a Lorentzian peak function. &#13;
 We discussed this simple and more sophisticated approaches for revealing network structures. Examples of studies from hydrogel networks are provided as important materials with polymeric networks in life science applications. Finally, the determination of mesh size distributions as a function of temperature, time and healing efficiency is discussed in detail.</abstract>

    <title language="eng">Nanoplastics Aqueous Dispersions as Polymer Reference Materials for a Sustainable Future</title>
    <abstract language="eng">The undesirable presence of micro and nanoplastics in our environment and in food is now common knowledge. However, it is unclear whether serious dangers and risks are posed by nanoplastics. A scientifically based reliable determination of the type and quantity of nanoplastics in complex matrices is of considerable importance for the future sustainable use of polymers. Here, reference materials help in the determination of nanoplastics. In particular, colloidally stable aqueous dispersions of nanoplastics appear suitable for this purpose. We report on the current status of the development of nanoplastics as reference materials. A detailed example of reference materials for characterizing nanoplastics is provided in the form of aqueous dispersion of polypropylene. The nanoplastics samples are colloidal stable for at least two years at ambient conditions. A low zeta potential of -35 mV at a neutral pH value provides stability. An overview of their colloidal properties in different environmental conditions is presented. Next, polyethylene nanoplastics will be compared to polypropylene nanoplastics. Nanoplastics consisting of poly(ethylene terephthalate) will be discussed and finally, we report on poly(L-lactic acid) as a typical and important representative of biodegradable polymers.</abstract>

    <title language="eng">A look inside nanoparticles</title>
    <abstract language="eng">Small-angle scattering is the method of choice when it comes to obtaining information about the interior of nanoparticles. The aim is to make nanotechnology safer. While the use of small-angle neutron scattering (SANS) is limited to a few instruments in the world, small-angle X-ray scattering (SAXS) is widely accessible, with an upward trend. The example of core-shell particles shows how simple their analysis is with data from an Anton Paar laboratory system. Here, SAXS is a central tool for the development of new reference materials based on poly(methyl) acrylate-PVDF core-shell particles. The dimensions of the cores and shells can be precisely determined. A detailed analysis makes it possible to show that the cores contain fluorinated and nonfluorinated polymers, whereas the shell consist only of PVDF. This core-shell particles with a diameter around 40 nm show a significantly higher PVDF beta phase content than the PVDF homopolymer when using an emulsion polymerization technique. This finding is of importance with respect to applications in electroactive devices.</abstract>

    <title language="eng">The Single Chain Architecture of (Bio)Polymers in Contact with Nanoplastics</title>
    <abstract language="eng">In contrast to microplastics, little is known about nanoplastics (1 to 100 nm). In order to make the dectecability of nanoplasics more reliable, we started to develop nanoplastic reference materials. This project also aims to anser the question of how the single chain conformation of bio(polymers) changes in contact with nanoplastics. Small-angle X-ray and neutron scattering methods are suitable methods for studing this topic. Recently the soft and hard interactions between polystyrene nanoplasics and human serum albumin corona was investigated with small-angle neutron scattering. Here we concentrate on small-angle X-ray scattering as our favorite method to study how (bio)polymers change their conformation in contact with nanoplastics. The scattering of bovine serum albumin in its native state can be detected easily. The scattering pattern of this biopolymer changes dramatically when its globular stucture changes to a coil structure. Modeling of chain conformations and the calculation of the scattering pattern is relatively easy to perform. Numerous model calculations will be provided to predict the changes of conformation of single bio(polymer) chains when in conatact with nanoplastics. These predictions will be compared with recent experimenal results from in situ measurments of bio(polymers) in contact with nanoplastics. The impact of temperature, polymer concentration and salt on the single-chain conformation changes will be discussed.</abstract>

    <title language="eng">(Bio)polymers tune the catalytic activity of silver nanoparticles</title>
    <abstract language="eng">We report on the development of ultra-small core-shell silver nanoparticles synthesized by an up-scaled modification of the polyol process. It is foreseen to use these thoroughly characterized particles as reference material to compare the catalytic and biological properties of functionalized silver nanoparticles. Small-angle X-ray scattering (SAXS) analysis reveal a narrow size distribution of the silver cores with a mean radius of RC = 3.0 nm and a distribution width of 0.6 nm. Dynamic light scattering (DLS) provides a hydrodynamic radius of RH = 10.0 nm and a PDI of 0.09. The particles’ surface is covered with poly(acrylic acid) (PAA) forming a shell with a thickness of 7.0 nm, which provides colloidal stability lasting for more than six months at ambient conditions. The PAA can be easily exchanged by biomolecules to modify the surface functionality. Replacements of PAA with glutathione (GSH) and bovine serum albumin (BSA) have been performed as examples. We demonstrate that the particles effectively catalyze the reduction of 4-nitrophenol to 4-aminophenol with sodium borohydride. The tunable catalytic activity of (436 ± 24) L g-1 s-1 is the highest reported in literature for silver nanoparticles.</abstract>

    <title language="eng">Challenges of synthesis and analysis of core-shell nanoparticles for reference materials</title>
    <abstract language="eng">Core-shell nanoparticles are widespread in nature, industrial applications and nanotechnology research. Facile ways of modern synthesis will be discussed and possibilities to reveal their structures with small-angle X-ray scattering (SAXS). A recent review on using block copolymer templates as one of the most reliable routes for tuning size and shape of nanoparticles is provided by Li et al.1 Ferritin and apoferritin are archetypical examples for protein-based core-shell nanoparticles. Their structures are easily accessed by synchrotron SAXS2 but also with commercial instruments and allow fast performance tests.3 SASfit4 is a suitable program tool based on classical curve fitting and McSAS5 is a complementary program based on a Monte Carlo technique. Detailed refinements of SAXS data evaluation are on the way for better data analysis.6 A sub nanometer resolution is state-of-the-art for quantification of the size distribution of polyacrylic acid stabilized silver nanoparticles.3 Such particles are useful in catalysis.7 It was observed that the catalytic activity can be tuned easily by varying the shell material of the particles.</abstract>

    <title language="eng">SAXS for the development of reference materials: Silver nanoparticles, a case study</title>
    <abstract language="eng">Today there are hundreds of products available containing silver in form of nanoparticles, so-called nanosilver. This situation and the foreseeable future growing market of nanosilver will supposedly cause an increased release of silver into the environment. In this way, silver can be also incorporated into the human body and accumulated in different organs, which can be toxic or at least an unknown risk to human health. For these reasons, it is important to constantly study materials containing silver nanoparticles, their production, application in products and technical processes, dissemination of silver nanoparticles in the environment, and effects on humans and nature. The state-of-the-art nanoparticle size and concentration characterization are illustrated in an extensive interlaboratory comparison. To guarantee the traceability of measurements and to secure the comparison of results of different analytical methods, reference materials (RM) and certified reference materials (CRM) are essential. As a case study, the objective of the presented project was to provide an aqueous suspension of silver nanoparticles as a reference material with a nominal diameter below 10 nm for application in the determination of the size and concentration of nanoparticles in an aqueous surrounding. Measurands are the particles’ diameter D, size distribution width σ, number density N, and concentration c. Target uncertainties, defined as one sigma of the measurand values, are 5% for D, 10% for σ, 20% for N, and 20% for c. The certification was carried out based on ISO 17867 and the relevant ISO-Guides to produce reference material. The process of using SAXS as a reliable method for testing homogeneity and short-term and long-term stability of the material is reported. The particle preparation is described in detail so that the user can carry out the steps of synthesis and characterization in his own laboratory if required. Optionally, one can also contact the author for the provision of the silver nanoparticles. Detailed information can be found elsewhere (BAM Certification Reports, BAM-N008 (2022)).</abstract>

    <abstract language="eng">Hydrogel properties are largely determined by their network structure. Here, we report on the capabilities of SAXS methods for characterizing polymer-network gels. SAXS provides rich insight into different types and levels of nanostructural inhomogeneities in these soft matter materials. The structure analysis of alginate hydrogels, typically utilized in tissue engineering applications, will be discussed in detail.</abstract>

    <title language="eng">Developtment of Nanoplastics Reference Materials at BAM</title>
    <abstract language="eng">Engineered particles are essential for sustainable innovation and modern industrial applications, but their reliable, number‑based characterisation remains a major challenge. Regulatory frameworks in healthcare, personal care (EU 745/2017, 749/2017, 1223/2009), and environmental monitoring—such as the EU Drinking Water Directive 21840/2020—demand robust particle measurements across complex matrices. Yet standardised methods currently exist only for simple particle systems, leaving significant gaps for technologically relevant materials and for micro‑ and nanoplastics as emerging pollutants. These challenges are amplified by the lack of well‑defined input parameters, particularly density and refractive index, which are critical for many analytical and modelling approaches.&#13;
This talk highlights BAM’s work on developing nanoplastics reference materials to support validated, traceable, and harmonised measurement methods. I will outline strategies for producing stable, well‑characterised polymeric nanoparticles, establishing accurate material parameters, and integrating these reference materials into interlaboratory and standardisation activities. These efforts provide the metrological foundation urgently needed for regulatory testing, environmental monitoring, and industry innovation.</abstract>
