Resumen:
Here we present the features that modify nanoparticles movility and consequent changes in bioavailability. This changes are modified by different patways of degradation that can be used for removal of such materials from compromissed environmental organic matrixes.The toxicity and ecotoxicity of the most used nanomaterials are presented and case studies like the effect of TiO2 on Daphnia or the interaction of fullerenes with Eschericcia coli are summariazed. The main physiological pathway thourgh which NMs affect living organisims is the generation of reactive oxygen species that trigger infflamatory responses and DNA alterations that could lead to cancer. Finally a pool of bioassays that are currently used to test nanomaterials toxicity is presented, like Ames test, micronucleus assay, High-throughput screening, Screen-printed electrodes and others.
