Imagine shrinking barcodes a million times, from millimetre to nanometre scale, so that they could be used inside living cells to label, identify and track the building blocks of life or, blended into inks to prevent counterfeiting. This is the frontier of nanoengineering, requiring fabrication and controlled manipulation of nanostructures at atomic level.

Colder than in outer space, higher pressure than 30 sperm whales on a stamp, and super magnets that could hold two Eiffel Towers: The search for new quantum materials - the materials of the day after tomorrow - is taking place today under extreme conditions. Yet it is often difficult to understand what the researchers actually do in their high-performance laboratories.

Researchers have investigated the effects of nanosilver, currently used in almost 450 products for its antibacterial properties, on the algae known as Poterioochromonas malhamensis. The results show that nanosilver and its derivative, ionic silver, disturb the alga's entire metabolism. Its membrane becomes more permeable, the cellular reactive oxygen species increases and photosynthesis is less effective.
