As nanotechnology and nanomaterials continue to be further developed, particularly in nanomedicine, not only are new approaches being researched to treat complex diseases, but they are also becoming available in large quantities for everyday use. This accessibility offers many novel possibilities to contextualize nanomaterials in applications for hygiene and medical products, such as cleaners, dressings, and plasters. Weighing the potential versus the risks of using this technology in everyday products provides multiple learning opportunities, which have already been presented in some articles about silver nanomaterials [1, 2]. The focus in chemistry classes here is often on synthesis, unique properties, the possible benefits, and the potential hazards to humans and the environment.

Further, more in-depth learning opportunities in chemistry lessons can be initiated with the integration of modern instrumental analysis methods. On the one hand, the use of low-cost technology can make otherwise cost-intensive equipment such as spectrometers more accessible in STEM lessons. On the other hand, the digital networking of this equipment can be used to discuss the measurement results and their relevance in a collaborative approach. The LabPi measuring station serves as an example of such a cost-effective solution [3].

The combination of nanotechnology and measuring stations thus enables better connection of current research topics with related analytical methods like spectro- and photometry. This creates further learning opportunities for meaningfully embedding the topic of nanotechnology in chemistry lessons and deepening knowledge of important chemical analysis methods.

In this article, the quantitative determination of silver nanoparticles using commercially available silver nanoparticles will be compared to those from a synthesis suitable for school use and presented for photometric determination in an everyday product.
