Firefly bioluminescence has attracted a lot of attention because of its extremely high efficiency — a quantum yield of 88%, as reported by Seliger and McElroy in 1959. However, two years later ...

In a firefly, on the other hand, nearly 100% of the energy is given off as light. That luminescence, or "cold light," as it's also called, is produced in the light cells and then focused by a ...

Two solutions are combined in a darkened room, producing luminescence that lasts for several seconds. Peroxides act as an oxidizing agent. The luminol is converted to an excited-state product. This ...

“We tried firefly luciferase first, and it was very hard to do the conjugation,” says Rao. “The reason was probably that the firefly luciferase is very fragile and sensitive to any chemical ...

The players behind Firefly, a glow-in-the-dark petunia, share the backstory behind this illuminating discovery and how they ...

The modified plants exhibit a gentle green luminescence in the dark by incorporating ... The genetic modification in Firefly Petunias enables them to produce similar enzymes, replicating the ...
