The effect of microplastics (MP) exposure on the chironomid species Chironomus riparius Meigen, 1804 was investigated using the OECD sediment and water toxicity test. Chironomid larvae were exposed to an environmentally relevant low microplastics concentration (LC), a high microplastics concentration

Our previous results on the phagocytic activity of alveolar macrophages (Mϕs) toward poly(lactic-co-glycolic) acid microspheres (PLGA MS) loaded with the anti-tuberculosis agent rifampicin (R-PLGA MS) suggest that the phagocytosis of R-PLGA MS enhances the phagocytic activity of Mϕ cells. To

The separation efficiencies of three different asymmetrical flow field-flow fractionation (AF4) channel designs were evaluated using polystyrene latex standards. Channel breadth was held constant for one channel (rectangular profile), and was reduced either linearly (trapezoidal profile) or exponentially (exponential profile)
