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.

Researchers have created a serpentine path for electrons, imbuing them with new properties that could be useful in future quantum devices.
The quantum sensing abilities of nanodiamonds can be used to improve the sensitivity of paper-based diagnostic tests, potentially allowing for earlier detection of diseases such as HIV.
Scientists have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods.
