Nano-Silver Can Penetrate Human Cells and Cause Damage

Endocrine disrupters are not the only worrying chemicals that ordinary consumers are exposed to in everyday life. Also nanoparticles of silver, found in e.g. dietary supplements, cosmetics and food packaging, now worry scientists. A new study from the University of Southern Denmark shows that nano-silver can penetrate our cells and cause damage.

Major Project to Investigate Safety of Nanoparticles in Facade Paint

Five Empa laboratories were involved in the EU «NanoHouse» project, along with four other European research institutes and four industrial partners. The aim of the project was to investigate the opportunities and risks presented by the nanomaterials used in the surface coatings applied to building façades. For the first time not only were freshly manufactured products studied to see if they set free nanoparticles, but also aged samples.

New Method for Accurate Determination of Nanomaterial Toxicity

EPFL researchers have developed a method for accurately determining the toxicity of nanomaterials. By using optical techniques, they are able to measure the concentration of the oxidizing substances produced by a damaged cell. Furthermore, this research also offers a new way to know more about the mechanisms of oxidative stress.

Nanotoxicology Study Focuses on Effects of Nanoparticles on Human Immune System Cells

In a growing number of industries, workers are often unknowingly exposed to nanoparticles (NPs). Do they enter the body? Could they have an impact on health? Professor Denis Girard from the INRS–Institut Armand-Frappier Research Centre has had the foresight to study the potential toxicity of a wide variety of NPs with a view to setting the record straight before problems occur.
