Scientists develop tunable gold-polystyrene tracer nanoparticles that allow nanoplastics to be tracked in freshwater ecosystems, supporting critical research on plastic pollution.
Researchers developed hypothermal opto-thermophoretic tweezers that use low laser power and cooling to precisely manipulate cells and nanoparticles without damage.
This discovery could lead to devices that store and process information in novel ways using this technology without the need to keep them at ultra-low temperatures.
