“…In ultrapure water, silver nanoparticles prepared with colloidal silver were adsorbed on the surface of the NPs. After being dried, the NPs act as nuclei to attract surrounding silver nanoparticles, and the latter play a role in amplifying signals [ 34 ]. After scanning, the characteristic peaks of the PP group were at 841, 971, 1149, and 1451 cm −1 , that of the GCPP group were at 971, 1322, and 1451 cm −1 , and in the PE group, they were at 1059, 1125, 1289, and 1429 cm −1 ( Figure 6 a–c).…”

Understanding of the potential leaching of plastic particles, particularly nanoplastics (NPs), from food packaging is crucial in assessing the safety of the packaging materials. Therefore, the objective of this study was to investigate potential exposure risks by simulating the release of NPs from various plastic packaging materials, including polypropylene (PP), general casting polypropylene (GCPP) or metalized casting polypropylene (MCPP), polyethylene (PE), polyethylene terephthalate (PET), and polyphenylene sulfone (PPSU), under corresponding food consumption scenarios. Surface-enhanced Raman scattering (SERS) and scanning electron microscopy (SEM) were utilized to identify and characterize the NPs leached from plastic packaging. The presence of separated NPs was observed in PP groups subjected to 100 °C hot water, GCPP plastic sterilized at a high temperature (121 °C), and PE plastic soaked in 100 °C hot water, exhibited a distorted morphology and susceptibility to aggregation. The findings suggest that the frequent consumption of takeaway food, hot beverages served in disposable paper cups, and foods packaged with GCPP materials may elevate the risk of ingestion of NPs. This reminds us that food packaging can serve as an important avenue for human exposure to NPs, and the results can offer valuable insights for food safety management and the development of food packaging materials.

“…Although the LOD achievable with Ag-perovskite SERS substrates may not be as low as that of Ag deposited on other materials such as glass or Si, 39 the standalone measurement of the latter typically captures unwanted fluctuations in the Raman signal, which are regarded as noise and can significantly impede the detection of low-concentration analytes when using such substrates for SERS detection. In contrast, Agperovskite SERS substrates exhibit a significantly low Raman background signal, substantially mitigating this drawback.…”

Metal nanoparticles are currently one of the most researched materials in the field of science and technology. These materials are up to one hundred nanometers in size and differ from ordinary metals in their unique physical and chemical properties.The use of metal nanoparticles in biomedicine is one of the most promising areas of theire application. For example, gold nanoparticles can be used to diagnose and treat cancer. Gold nanoparticles can be coated with various molecules that can target and interact with cancer cells, allowing cancer to be detected and staged. Silver nanoparticles can be used as antimicrobial agents, since silver has a high activity against bacteria and fungi. Also, silver nanoparticles can be used to treat wounds, as they promote rapid healing and prevent infections.Metal nanoparticles are also applied in other industries e.g. to produce electronics, improve the properties of materials, manufacture catalysts, and many other things that are used both in everyday life and in the production and improvement of technological processes. This article discusses the use of metal nanoparticles of silver (AgNPs), zinc (ZnNPs), titanium oxide (TiO 2 NPs), and gold (AuNPs) in biomedicine and other fields.
