Glowing Plants: Cheap Nanoparticles Turn Succulents into Night Lights

Researchers at South China Agricultural University have developed a low-cost, biocompatible phosphor compound that allows succulents to glow for up to two hours after just a few minutes of sunlight or LED exposure. This inexpensive method, involving injecting nanoparticles into the leaves, avoids complex genetic modification techniques. The team found an optimal nanoparticle size for uniform, bright illumination, even enough to light nearby objects. The technology could revolutionize indoor and garden decor, creating stunning, glowing landscapes at minimal cost (around $1.4 per plant). Long-term safety studies are underway.
