In the episode "Cold Blood", the Eleventh Doctor experiences excruciating pain when the Silurian attempts to decontaminate him of surface bacteria. The Doctor states this would kill him, most likely due to the scanners being programmed to "detox" humans and therefore being unaware of what elements the Doctor requires.
