“…The latest research showed that exposure of adult zebrafish ( Danio renio ) to 70 nm NP-PS at doses of 0.5 and 1.5 ppm for 7 days resulted in their accumulation in tissues, among others in the liver, intestines, brain and gonads, lead to disorders of lipid and energy metabolism and induced oxidative stress [ 43 ]. In other studies, an increase in the activity of CAT, SOD and GSH enzymes in visceral fat, gills and mantle was observed in Corbicula fluminea mussels exposed to 80 nm polystyrene nanoparticles at concentrations of 0.1, 1 and 5 mg/L [ 48 ].…”

With the ongoing commercialization, human exposure to plastic nanoparticles will dramatically increase, and evaluation of their potential toxicity is essential. There is an ongoing discussion on the human health effects induced by plastic particles. For this reason, in our work, we assessed the effect of polystyrene nanoparticles (PS-NPs) of various diameters (29, 44 and 72 nm) on selected parameters of oxidative stress and the viability of human peripheral blood mononuclear cells (PBMCs) in the in vitro system. Cells were incubated with PS-NPs for 24 h in the concentration range of 0.001 to 100 µg/mL and then labeled: formation of reactive oxygen species (ROS) (including hydroxyl radical), protein and lipid oxidation and cell viability. We showed that PS-NPs disturbed the redox balance in PBMCs. They increased ROS levels and induced lipid and protein oxidation, and, finally, the tested nanoparticles induced a decrease in PBMCs viability. The earliest changes in the PBMCs were observed in cells incubated with the smallest PS-NPs, at a concentration of 0.01 μg/mL. A comparison of the action of the studied nanoparticles showed that PS-NPs (29 nm) exhibited a stronger oxidative potential in PBMCs. We concluded that the toxicity and oxidative properties of the PS-NPs examined depended to significant degree on their diameter.

“…Atomic force microscopy (AFM) can be used to characterize the NPs separated by ultracentrifugation, while transmission electron microscopy (TEM) images can be used to characterize the morphology changes of nanoparticles (Weinberg et al, 2011). Li et al (2020a) observed the size and morphology of NPs by scanning electron microscope (SEM) and transmission electron microscope (TEM). Optical microscopy techniques such as electron microscopy and confocal laser scanning microscopy (CLSM) can be used to characterize the structures and particles of several NPs (Picó et al, 2017).…”

“…Some studies showed that the toxicity of NPs to organisms was mainly due to the oxidative damage induced by NPs (Sun et al, 2018;Zhu et al, 2019). Li et al (2020a) showed that the freshwater benthic Corbicula fluminea would undergo excessive oxidative stress reaction with the increase of exposure concentration, and the change of enzyme activity was the main manifestation of oxidative stress and damage. Excessive oxidative stress will lead to oxidative damage, and ROS will induce lipid peroxidation.…”

“…Although there are some controversies about the definition of NPs, the definition of NPs with a particle size of 1-100 nm is generally accepted by researchers (Gigault et al, 2018;Li et al, 2020c;Zhang et al, 2020a;Qu et al, 2019a). NPs have higher cell affinity, smaller size and surface curvature, and higher surface area and volume, making it easier to penetrate freshwater biological barriers and accumulate in organs (Au et al, 2017;Kolandhasamy et al, 2018;Li et al, 2020a).…”

“…NPs are widely used in cosmetics, electronics, biosensors and medicine (Li et al, 2020a;Wagner et al, 2015;Cedervall et al, 2012;Fabricius et al, 2014). Especially in the field of medicine, they have great potential in diagnosis and treatment, such as drug delivery (Cedervall et al, 2012;Chen et al, 2011).…”

Fibre‐based wearables for embroidery, chemosensing, and biofluid's unidirectional draining with good flexibility, tunability, and designability drive technological advance. However, synthetic polymer fibres are non‐degradable, threatening the environment and human health. Herein, we have developed versatile microfibre‐based wearables by combining many advantages in one platform of biodegradable polylactic acid (PLA) and melt electrowriting strategy. Diverse potential applications of PLA wearables are achieved by flexibly designing their printing files, components and structures. Three‐dimensional printing files are generated from two‐dimensional images to fabricate ‘embroidery‐like’ patterns. PLA/aggregation‐induced emission fluorogens (AIE) chemosensors exhibit colorimetric and fluorescent colour changes upon exposure to amine vapours. Janus PLA‐cotton textiles with a hydrophobic/hydrophilic structure could facilitate unidirectional draining of sweats which is favourable for the management of temperature and humidity on the surface of skin. The proposed platform can not only broaden the design possibilities in 3D/4D printing but also offer wide potential applications for functional wearables.
