Abstract

Emerging applications of nanomaterials are a promising area for the development of new functional food products. However advantages and limitations of nanotechnology applications are not fully understood and it is need to evaluate the potential risks of these nanomaterials. This study evaluates the toxicity of mesoporous silica nanoparticles in life cycle of C. Elegans. Mean life cycle decreased 3 days below normal response confirming the toxic risks of nanoparticles on a primary living model. However the surface functionalization of nanoparticles was able to recover the mean life of nematodes to normal response at 11 days. Lifespan data was correlated with healthspan variables and the surface nanoparticles functionalization recovers the nematode activity related to mobility and its offspring. Those results open an interesting way of research on nanomaterials and its surface functionalization to get useful applications on food technology minimizing risk to human health.
