Thanks to nanotechnology the human eye can perceive its surroundings in the highest possible resolution. Now a Spanish startup is looking to nanotechnology to help prevent documents and products from being falsified. The key here: photo-sensitive microparticles. Integrated into ink, they are used to print security features in QR- and barcodes. As in current methods for bank notes, the...

Laser light helps to heal serious burns. A research team from Texas and Portugal has been experimenting with light to fight cancer and has discovered a new, low-cost way to protect healthy cells. The magic formula? Near infrared light from LED lamps combined with tin oxide nanoparticles. During treatment, the light causes the tin oxide particles to vibrate, thus...

Special glasses reduce age-related visual impairment. A healthy human eye can see with an astonishing resolution of 25,000 ppi, a density that no electronic display has ever matched. Until now. Enter a Swedish research team that, with the help of tungsten oxide, has reduced pixel size to 560 nanometres. Corresponding to the size of one light-sensitive receptor cell in...

New glasses make blind spots visible again. In Australia, however, a research team is focusing on how to treat retinal diseases such as macular degeneration in the early stages of the condition. Preferably without the need for the injections. Lipo-soluble pigments from Gac fruit were integrated into a solution similar to eye drops. Using nanotechnology allowed the pigments -...
