Phytoplankton disturbed by nanoparticles

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.

Vibrational encounters - phonon polaritons meet molecules

Scientists have employed a spectroscopic nanoimaging technique to study how infrared nanolight and molecular vibrations interact with each other. The images reveal that vibrational strong coupling can be achieved, which is a phenomenon that recently attracts wide attention for its potential use to control fundamental physical and chemical material properties.
