In vivo nanotoxicology: Toxicoproteomics

Sabella S., Kote S., Pompa P.P., Italian Institute of Technology, IT

Proteomics applied to nanotechnology is now emerging as an attractive tool to address the still unanswered questions dealing with nano-biointeractions and NPs-induced toxicity in living systems. The unique advantage provided by “omic” techniques (such as, [...]

Cell Culture Media elicit a different dynamic Formation of Protein-NP Complexes: Effects on the Cellular Response

Sabella S., Maiorano G., Sorce B., Brunetti V., Malvindi M.A., Cingolani R., Pompa P.P., Italian Institute of Technology, IT

We show that the dynamics of proteins-NP interactions are differently mediated by different cellular media, which are the liquid environments where NPs encounter cells. We used, as a model, spherical NPs (citrate-capped gold nanoparticles, AuNPs) [...]

Nanomaterials can influence living biological systems with nanometer sensitivity

Sabella S., Brunetti V., Maiorano G., Rizzello L., Sorce B., Vecchio G., Galeone A., Cingolani R., Pompa P.P., Italian Institute of Technology, IT

We show the different response of human neuroblastoma cells line to gold surfaces with different levels of nanoroughness, finding out that neurons are capable to sense and actively respond to these nanotopography features, with a [...]
