Health risk assessment of nanomaterials is a new and important area emerging; obtaining nanoparticles by green synthesis method and performing cytotoxicity, genotoxicity and antimicrobial testing is an important endpoint. In vitro studies for nanoparticles (NPs) obtained by the non-toxic method offer many advantages, such as the study of the bioavailability of nanomaterials to sensitiv...

OBJECTIVES The cytotoxicity induced by cobalt ions (Co2+) and cobalt nanoparticles (Co-NPs) which released following the insertion of a total hip prosthesis, has been reported. However, little is known about the underlying mechanisms. In this study, we investigate the toxic effect of Co2+ and Co-NPs on liver cells, and explain further the potential mechanisms. METHODS Co-NPs were characterise...

Abstract Background Bioanalytical tools have been shown to be useful in drinking water quality assessments. Here, we applied a panel of vitro bioassays assess the treatment efficiency two pilot-scale treatments: ozonation and granular activated carbon (GAC) filtration at plant (DWTP). The systems were studied alongside full-scale process consisting biological (BAC) filtration, UV disinfection, ...

Potentially, the toxicity of multiwalled carbon nanotubes (MWCNTs) can be reduced in a safe-by-design strategy. We investigated if genotoxicity and pulmonary inflammation MWCNTs from same batch were lowered by a) reducing length b) introducing COOH-groups into structure. Mice administered: 1) long pristine MWCNT (CNT-long) (3.9 μm); 2) short CNT (CNT-short) (1 3) modified with high ratio (CNT-C...
