Nano-coating to protect buildings against pollution
Nano-coating to protect buildings against pollution The photocatalytic properties of anatase , one of the three naturally occurring forms of titanium dioxide , were discovered in Japan in the late 1960s.
Designing ultra-sensitive biosensors for early personalised diagnostics
Designing ultra-sensitive biosensors for early personalised diagnostics Personalised medicine is one of the new developments that is deemed to revolutionise health care. A key component is the detection of biomarkers, proteins in blood or saliva, for example, whose presence or abnormal concentration is caused by a disease.
Pietro Gucciardi – Working towards a single-molecule biosensor
Pietro Gucciardi – Working towards a single-molecule biosensor Until now, few biosensors have had the required sensitivity to detect single molecules. A novel approach for improved biosensor sensitivity has opened new avenues for developing new kinds of biosensors.
Nanosilver in textiles – friend or foe?
Nanosilver in textiles – friend or foe? Silver has been used as biocide for medical purposes since the 1930s. Today nanometric size silver particles are used to prevent unpleasant odour caused by bacteria in sport shirts or socks .
Jànos Nagy: On nanopportunities
Jànos Nagy: On nanopportunities These cylinders of precisely ordered carbon atoms are finding uses in a wide variety of industries due to their unique mechanical, electrical and thermal properties. Jànos B.
Revamping nanotubes
Revamping nanotubes Carbon nanotubes (CNTs) are set to become an important material for the future. That’s because they are light, robust, and highly conductive, both electrically and thermally whilst still being chemically stable.
Gold nanoparticles enhance cancer diagnostics
Gold nanoparticles enhance cancer diagnostics Gold nanoparticles ( AuNPs ) present the many advantages of displaying relative biocompatibility, high light absorption and strong optical scattering properties. They are therefore good candidates to be used as probes for cancer imaging .
Regenerating the Ear and the Eye
Regenerating the Ear and the Eye Finnish researchers have designed tiny nano-particles which can deliver a specific drug to cells of the inner ear. Once brought into position, this drug helps to repair damaged cells .
Nanoparticle therapeutics helping hearing disorders
Nanoparticle therapeutics helping hearing disorders Due to different anatomic and physiological barriers it is hard to treat hearing disorders by using conventional systemic drug delivery. Therefore scientists are investigating different ways to locally apply drugs using nanoparticles.
Nanoparticles in our cities: any risks for our health?
Nanoparticles in our cities: any risks for our health? Dr. Anne Beeldens and colleagues at the Belgian Road Research Centre have tested air purification efficiency by TiO2 NP-containing pavement blocks on parking lanes in Antwerp.
Could nanoparticles in cosmetics be toxic?
Could nanoparticles in cosmetics be toxic? NPs in cosmetics are especially used as UV filters in sunscreens. Nano-sized titanium dioxide (TiO2) and zinc oxide (ZnO) have been widely used for years.
Uncertainties surrounding nanoparticles aimed for medical use
Uncertainties surrounding nanoparticles aimed for medical use Researchers are trying to find out more about the relationship between different NPs’ shapes, sizes and surface chemistries and how they behave in the human body.
