The silk is produced by transgenic silkworms with embedded jellyfish or coral GFP-like genes. By processing the silk at low-temperature, luminescent material remains in the silk and provides fluorescence, e. g., on LED illumination. The manufacturing process has been cleared according to the Carthagena protocol and is said tob e implemented in summer 2014.
