The rapid development of nanotechnology has led to an increase in the number and variety of engineered nanomaterials in the environment. Gold nanoparticles (AuNPs) are an example of a commonly studied nanomaterial whose highly tailorable properties have
We reported previously that uptake of polystyrene nanoparticles (PNP) from apical fluid into primary cultured rat alveolar epithelial cell monolayers (RAECM) takes place in a manner dependent on exposure time and dose. Classical endocytosis pathways do not appear to play a role in the uptake of ...
In our research, the main focus is the aspect ratio-dependent internalization mechanism of rod-like nanoparticles, which have the monodispersed diameter and behave the same physiochemical nature. Whether the TMV short rods still have bio-activity after ultrasonication treatment is very important. TMV ...
This study focuses on the size-dependent uptake of MP by two freshwater Ciliophora, Tetrahymena pyriformis, Paramecium caudatum and one Amoebozoa, Amoeba proteus, serving also as predator for experiments on potential trophic transfer. Size-dependent uptake of MP in all three unicellular eukaryotes was...
GoldMag nanoparticles (GMNPs) possess the properties of colloid gold and superparamagnetic iron oxide nanoparticles, which make them useful for delivery, separation and molecular imaging. However, because of the nanometer effect, GMNPs are highly toxic. Thus, the biosafety of GMNPs should be fully...
The size-dependent mechanisms that contribute significantly to a shortening of T2 and typical dephasing times for gold, silver, and sodium nanoparticles for three different nanoparticle sizes are summarized in Table 1. After the initial dephasing processes, which occur on the fs-time scale, further ...
For silica nanoparticles of spherical and rod-like shape it has been shown that they were all taken up by macrophages, although the endocytosis pathway was dependent on the particle g eometry54. The localization of internalized silica particles inside NR8383 cells after 24 h of exposure ...
Mice instilled with silica nanoparticles (NPs) of 50 nm diameter without surface modification (50 nm-plain) exhibited a significant time-dependent reduction in body weight up to 72 h (Fig.1A). Mice instilled with silica NPs of 50 nm diameter with amine surface modifications (50 nm...
