Organic matter
From Tardis Wiki, the free Doctor Who reference
Organic matter was matter formed from organic compounds. Species formed from it were known to be referred to as "organics". (TV: The Timeless Children)
Wormholes would destroy organic matter, forcing organic species to travel through them in metallic protection. (TV: Planet of the Dead)
Dalek nanoclouds automatically processed any organic matter, living or dead, into Dalek puppets. (TV: Asylum of the Daleks)
The Cyberium's death particle was capable of destroying all organic matter in the universe. Following it being shrunk by the Tissue Compression Eliminator, its range became limited to a single planet. When it was detonated, it wiped out all organic matter left on Gallifrey. (TV: The Timeless Children)
