TL;DR: In this paper , the effect of PET nanoparticles (PET-NPs) (≤ 250 d.nm) was assayed on mouse macrophages cell line (RAW 264.7) in in vitro experiments, and the results showed that 15 μg/mL of nanoparticles concentration had exhibited effects in cell proliferation and a slightly increased production of reactive oxygen species (ROS), which seems to trigger cell response as foreign particles related to upregulation of PCDH12, IGH-V10, ROBO1 genes, and cell maintenance functions, related to FTSJ2 gene upregulation.

Unraveling the potential human health risks from used disposable face mask-derived micro/nanoplastics during the COVID-19 pandemic scenario: A critical review
TL;DR: In this article , the potential toxicity of mask-derived MP/NPs, such as gastrointestinal toxicity, pneumotoxicity, neurotoxicity, hepatotoxicity and reproductive and transgenerational toxicity, and the underlying mechanism were discussed.
Journal ArticleDOI
Data analysis in spectroscopic STXM
TL;DR: In this article , the basics of how to go from raw data to information about the sample are discussed, including data reduction, descriptive and model-based analysis, and available software, with examples taken from the literature.

Spectro‐Microscopic Techniques for Studying Nanoplastics in the Environment and in Organisms
TL;DR: It is argued that an analysis procedure should involve both particle imaging and correlative or direct chemical characterization of the same particles or samples, and methods that can do both simultaneously but have as downside that large particle numbers and statistics cannot be obtained.

Method for nanoparticles uptake evaluation based on double labeled fluorescent cells scanned in enhanced darkfield microscopy.
Mona Mihailescu,Luminita-Claudia Miclea,Ana Maria Pleava,Nicolae Tarba,Eugen Nicolae Scarlat,Mihaela G. Moisescu,Tudor Savopol +6 more
TL;DR: In this article , a method that integrates the standard imaging tools for locating and detecting unlabeled nanoparticles (NPs) with computational tools for partitioning cell volumes and NPs counting within specified regions to evaluate their internal traffic is presented.
