Search for: [Abstract = "tested NPs. Hemolytic activity was observed only in case of SiO2 NPs, especially the amorphous form. It was also demonstrated that all NPs, once in solutions, underwent aggregation and showed an instable dispersion.In summary, the results confirmed bioreactivity of airborne particles, which was demonstrated by up\-regulation of genes involved in inflammation and repair processes in both the bronchial epithelium and vascular endothelial cells. It was also shown that the same concentration of PM2.5 collected in different places produced various degrees of cytotoxicity, which strongly depended on chemical composition of particles. Experiments on different types of NPs showed that despite no immediate decrease in cell viability, NPs were able to affect normal cell function, including migration activity. Further studies are needed to elucidate various mechanisms underlying harmful effects of PM2.5 on human health."]
