Environmental safety of nanocellulose: an acute in vivo study with marine mussels Mytilus galloprovincialis

Abstract

The growing application of nanocellulose in various industrial sectors with potential release into the natural environment demands for safety assessment and thus ecotoxicity. Here we tested two types of cellulose...

Silver Nanoparticles Supported onto TEMPO-Oxidized Cellulose Nanofibers for Promoting Cd2+ Cation Adsorption

“…As a further characterization, ζ -potential measurements were conducted on the samples. Even if the measurements were not conducted on spheres, but on fibers, so that they cannot be related to DLS-size analysis, they provide a qualitative but clear trend of the ζ- potentia, confirming what has been recently reported in the literature: 61 a negative value is observed due to the introduction of carboxylic groups on the nanofiber backbone ( Table S2 , entry 3 in the SI). Surprisingly, the loading of AgNPs further promotes the decrease of the ζ-potential, suggesting an increment of negative charges on the surface of the resulting nanocomposite ( Table S2 , entry 6 in the SI).…”
