Summary: This study investigated the long-term effects of silver nanoparticles (AgNPs) on the structure and function of polymethyl methacrylate (PMMA) microplastic biofilms. The results showed that long-term exposure to AgNPs reduced the stability of bacterial communities on microplastics and cumulatively inhibited nitrogen removal and N2O emissions in eutrophic water.

Summary: Safe application of nanoparticles in medicine requires a full understanding of their pharmacokinetics and degradation in the organism. In this study, a magnetic spectral approach was used for in vivo monitoring of magnetic particle degradation, revealing the significant influence of parameters such as dose, size, surface coating, and internal architecture on the degradation process. These findings provide deeper insights into particle degradation in vivo, potentially facilitating the rational design of nano- and microparticles with predictable long-term fate in vivo.

Summary: The aggregation kinetics of fragmental polyethylene glycol terephthalate (PET) nanoplastics in aqueous environment were studied under various chemistry conditions. It was found that the aggregation of PET nanoplastics increased with higher electrolyte concentrations and lower solution pH, especially in the presence of divalent cations. Additionally, the presence of humic acid was shown to significantly inhibit the aggregation of PET nanoplastics.

Summary: This study demonstrates that composting has a persistent passivation effect on Cd for 256 days. The contribution of humic substances (HS) to Cd passivation largely depends on the amount of humic acid-bound Cd (HA-Cd) rather than fulvic acid-bound Cd (FA-Cd). Moreover, the inoculation of Phanerochaete chrysosporium can enhance the binding ability of humic acid (HA) to Cd and improve the maturity of compost.

Summary: This study investigated the dissipation and metabolism of TBBPA in situ, finding that rice-wheat rotation and monocultural reed growth can accelerate the removal of TBBPA by stimulating anaerobic debromination and aerobic O-methylation, especially the oxidative skeletal cleavage pathway.

Summary: The study revealed that blood-mediated silver nanoparticles had minimal impact on fish behavior at the highest concentration, but resulted in histological alterations. Additionally, bioaccumulation of silver nanoparticles was observed in different organs of the fish, with the highest accumulation in the liver, followed by the intestine, gills, and muscles. Furthermore, the study showed that bioaccumulation of silver nanoparticles led to histopathological alterations, including damaged gill tissue and necrosis, predominantly at the highest concentration tested.

Summary: The evolution of nanotechnology has driven the growth of regenerative medicine and sparked great interest in studying the interaction between stem cells and nanoparticles. This study used Prussian blue nanoparticles as model probes to investigate the fate of nanoparticles in living cells. By combining live cell imaging and a pixel-based colorimetry method, the researchers achieved long-term monitoring and dynamic quantification of nanoparticles in living stem cells at the single-cell level. The results revealed the asymmetrical inheritance of nanoparticles during mitosis and their reduction during interphase, mainly due to lysosomal digestion. This study provides important insights into the fate of nanoparticles in cell cycles, which are essential for the rational design of nanoparticles in the future.

Summary: The study examined the effects of exposure to un-coated AgNPs or silver nitrate on the benthic deposit-feeding polychaete Capitella teleta. The results showed tolerance towards both AgNPs and AgNO3, with significant effects on reproduction and growth observed after eight weeks. Further investigations into the long-term effects of un-coated AgNPs on sediment-dwelling organisms are needed.

Summary: The developmental exposure to AgNPs results in increased likelihood of engaging in repetitive behaviors and reductions in resident microglial cells in offspring. Additionally, offspring exposed to AgNPs exhibit increased body fat, along with significant changes in gut microbial profiles, which are linked to behavioral and metabolic alterations.

Summary: The study found that the interaction between silver nanoparticles (AgNPs) of different sizes (10nm and 40nm) and the aquatic higher plant Salvinia minima under different exposure media conditions exhibited size-dependant effects, impacting plant growth and chlorophyll production. The toxicity pattern was linked to the dissolution rate of AgNPs, with smaller particles being more toxic relative to larger ones.
