Nano silica in foodstuffs could cause gastrointenstinal inflammation - Reduction required
The anti-caking agent silica E551 has been used for many years in the food industry as well as in toothpaste. Hanspeter Nägeli (UZH) and his... More
Printed 3D-structures from cellulose nanocrystals
Empa researchers have succeeded in developing an environment-friendly ink made of cellulose nanocrystals for 3D printing. As a result, microstructures with outstanding mechanical properties can... More
Nano cigarettes are less harmful
The 31st May is World No Tobacco Day, which was launched by the WHO in 1987. Every year 6 million people die from the consequences... More
Gecko-inspired multipurpose gripper
Robots generally need a gripper that adapts to three-dimensional surfaces. Such a gripper needs to be soft to adapt to a great variety of geometries,... More
Ultimate Natural Sunscreen
Chemists, materials scientists and nanoengineers at UC San Diego have created what may be the ultimate natural sunscreen. In a paper published in the American Chemical... More
The complex interplay of nanosilver and wheat roots
Scientists have hypothesized that silver nanoparticles (Ag-NPs) may act as “Trojan horses” entering living organisms and then releasing silver cations (Ag+) over time, causing toxicity.... More
Nanoparticles can travel from lungs to blood, possibly explaining risks to heart
Tiny particles in air pollution have been associated with diseases in heart or blood vessels (called cardiovascular disease), which can lead to premature death. But... More
Nanoparticles remain unpredictable
The way that nanoparticles behave in the environment is extremely complex. There is currently a lack of systematic experimental data to help understand them comprehensively,... More
