2. 1. Toxicity and biological impact of metal and metal oxide nanoparticles : Focus on the vascular toxicity of ultra-small titanium dioxide nanoparticles

   Author : Narges Bayat; Susana Cristobal; Janeck James Scott-Fordsmand; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Nanotoxicology; Ultra-small nanoparticles; Biochemistry; biokemi;

   Abstract : The application of nanoparticles (NPs) in different technologies has led to tremendous advancement in those fields.  Moreover, there is growing interest in application of ultra-small NPs (USNPs) at 1-3 nm due to their distinct molecule like features. Parallel to these promises, there is a growing concern regarding their safety. READ MORE

4. 2. Engineered nanomaterials in in vivo and in vitro models

   Author : Laura Abariute; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

   Abstract : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. READ MORE

5. 3. Raman Spectroscopy and Hyperspectral Analysis of Living Cells Exposed to Nanoparticles

   Author : Linnea Ahlinder; Lars Österlund; Ioan Notingher; Uppsala universitet; []
   Keywords : Raman spectroscopy; Hyperspectral analysis; Multivariate data analysis; Nanotoxicology; Graphene oxide; Iron oxide; Titanium dioxide; Cells;

   Abstract : Nanoparticles, i.e. particles with at least one dimension smaller than 100 nm, are present in large quantities in ambient air and can also be found in an increasing amount of consumer products. It is known that many nanomaterials have physicochemical properties that differ from physicochemical properties of the same material in bulk size. READ MORE

6. 4. Probing the Nano-Bio Interface Using Surface Based Analytical Techniques

   Author : Rickard Frost; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanotoxicology; cell membrane; nanomedicine; melanophores; QCM-D; nanomaterial; DPI; AFM; supported lipid bilayer;

   Abstract : In recent years, the use of manufactured nanomaterials has been rapidly increasing in a wide range of application areas. Among others, these areas of application include cosmetics, medicine, clothing, and sporting goods. The small size of nanomaterials offers unique properties that are not possible to obtain by the same material in bulk. READ MORE
