New technique lets popular houseplants glow for a little while—without genetic engineering



Summary

Scientists have developed a method to make common houseplants glow using silica nanoparticles without genetic modification. These nanoparticles, containing a light-emitting dye, are applied to the plants through their stomata, allowing them to be absorbed into the leaves. When exposed to blue or UV light, the plants emit a visible glow for a short period. The intensity and duration of the glow can be adjusted by varying the concentration and type of nanoparticles used. This technique offers a temporary and non-invasive way to create bioluminescent-like effects in houseplants.
