Skin protection against ultraviolet (UV) radiation is necessary to reduce sunburn damage (erythema) and has been recognized as an important preventive measure against the development of cancer. Many sun-blocking pharmaceutical products are based on titanium dioxide nanomaterials (TiO2 NMs) due to their UV barrier properties. This study aimed to assess if the UV protective efficiency of TiO2 NMs depends on their shape. We prepared TiO2 nanowires (TNW), TiO2 nanotubes (TNT), and TiO2 nanoplates (T...

Abstract This study, motivated to fill the knowledge gap on environmental safety of selenium nanoparticles (SeNPs), provides information on the stability and environmental safety of four differently coated SeNPs rendering both positive and negative surface charges. The stability and dissolution behaviour of SeNPs were determined in an aquatic model media of different ionic strength to provide information regarding the environmental fate of SeNPs in different environmental conditions. The environ...

Abstract Silver nanoparticles (AgNPs) represent one of the most abundant biocidal nanomaterials contained in more than 30% of nano-enabled consumer products and 75% of nanomedical products. The cumulative exposure of the general population may therefore reach critical and potentially hazardous levels. Due to data gaps on AgNP effects in humans, it is urgent to further evaluate their possible toxicity, particularly in vulnerable systems like the nervous one. As AgNPs may cross the blood brain and...

This study was designed to evaluate the nano–bio interactions between endogenous biothiols (cysteine and glutathione) with biomedically relevant, metallic nanoparticles (silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs)), in order to assess the biocompatibility and fate of nanoparticles in biological systems. A systematic and comprehensive analysis revealed that the preparation of AgNPs and AuNPs in the presence of biothiols leads to nanoparticles stabilized with oxidized forms of biot...

Using alkaline comet assay, DNA damage tail length (TL) and tail intensity (TI) parameters were compared between fresh whole blood and 1-year frozen small volume whole blood in EDTA at -80 oC without cryo-preservation. The studied group consisted of 25 volunteers with different health conditions who served as their own controls for frozen blood results. Without the purification step after thawing, the results and the usefulness of this protocol for future/retrospective (including re-analysations...
