Naturally occurring. Ore, used by Cardassians in the construction of warp drives.

Submitted by Alex Hoffmann


Laser tool in TNG: "Starship Mine"
Artificially generated by crew. Laser stands for "Light Amplification by Stimulated Emission of Radiation". Today, the laser is a commonly known and in many ways used bit of technology.

Origin unknown. A non-replicatable material, almost definitely an element, typically pressed into bars, like gold.


Naturally occurring. Particle whose "activity" indicates a wormhole shift. In real life, leptons are the "light" class of elementary particles. In the episode, it would have rather made sense if a specific particle had allowed the detection of the wormhole movement. 


Artificially generated by crew. A drug.

Submitted by Chad Eaton


Naturally occurring. Lithium was used in old warp drive systems before the application of dilithium became more common. Lithium is a real-world substance and there's nothing that points to the assumption that it could be penetrated by antimatter in the same way it happens to dilithium (i.e. without getting its atoms annihilated) However, the use of lithium in M/ARAs prior to TOS is contradicted by ENT (maybe it's still used in old warp-3 freighters).

Submitted by Alex Hoffmann


Origin unknown. Highly toxic; alters molecular structure when it comes in contact with glass. Stable in a nitrogen-oxygen atmosphere.




Artificially generated by crew or by aliens. In real life, a magn*e*ton (see below) represents the magnetic dipole moment of a particle. In short, it's a measurement, not a particle. A magnaton must obviously be something else.

Magneton pulse

Artificially generated by crew.

Submitted by Markus Göpfert


Artificially generated by crew. Synthetic alloy, needed in the construction of shield systems, only used by the Federation. Supplement by Bernd: Strangely, this sounds like a word made by combining mercury and potassium.

Submitted by Alex Hoffmann


Artificially generated by aliens. An explosive material used in out-of-date rockets which are no match for Federation weaponry.

Mercurium isochromat

Origin unknown. Used in drive systems. Supplement be Bernd: Equally colored mercury?

Submitted by Alex Hoffmann


Artificially generated by aliens. Sedative, has no effect on patients who took makara herbs.

Submitted by Alex Hoffmann


Naturally occurring. Particle "activity" increased prior to the wormhole reappearing and shifting its position.

Metaphasic particles

Naturally occurring. True nature uncertain.

Metaphasic shield

Shuttle with metaphasic shield in TNG: "Suspicions"
Artificially generated by crew. A subspace technology which involves generating metaphasic properties.


Naturally occurring. Real compound with the formula CH4.

Submitted by Ari "borgboy" schwartz


Artificially generated by crew. A painkiller.


Artificially generated by crew. A drug.

Metreon gas

Naturally occurring. Inflammable gas. High levels of exposure can infect a humanoid with metremia, a blood disease that causes its victims' cells to undergo fission.

Submitted by Alex Hoffmann


Origin unknown. Monotanium is an extremely strong metal used in the construction of starship hulls. The "mono " prefix may refer to the fact that it may be thinner, yet stronger than tritanium.

Submitted by Derek Seewald


Naturally occurring. A particle. Short-lived subatomic particle classified as a lepton.

Update by Alex Hoffmann


Naturally occurring. Assumed naturally occurring (like boridium) seeing as how it was used by the Hill People of the Argus River region of Rigel II. Could be a chemical compound (i.e. native stone).

Submitted by Scott Gray




Nadion pulse in TNG: "The Mind's Eye"
Artificially generated by crew. The TNG Technical Manual identifies "nadion" particles as the output produced by phasers.

Submitted by Matt Anderson

Neodilithium (unconfirmed)

Naturally occurring. Seems to be a different form of dilithium.

Neurogenic field / radiation

Naturally occurring. A resident field that forms by a person's brain as part of the thought process. Each person's pattern varies depending on their current thought.


Naturally occurring. Neuropeptides are chemical substances in the brain. Peptides are, as far as I know, indeed part of our organic system.

Submitted by Fabian W.

Neurozine gas

Artificially generated by crew and by aliens. Anesthetic gas. Fatal if present in the air (similar to anesthezine). The fact that it is used by Starfleet doctors suggests out that this gas should not be the same as the lethal Cardassian "neurocine". On the other hand, it has pretty much the same effect, and the spelling difference is only like that of present day British and American English. Perhaps Starfleet employs a much lower dose of the same substance that would not be lethal.

Submitted by Alex Hoffmann


Artificially generated by crew. A particle involved in several different processes. Real particle with no charge, until recently thought to have no mass.


Naturally occurring. A particle. Neutrons are neutral particles which, along with protons, are constituents of atomic nuclei. Neutrons not contained within a nucleus have a half-life of about 15 minutes.


Naturally occurring or artificially generated by aliens. A very dense and strong material. Matter composed of densely packed neutrons, held together by gravity. The material neutron stars are made of.


Naturally occurring. A metal used in an important alloy commonly found in starships.


Naturally occurring. A metal. The melting point of one alloy with this metal is 2014°F.

Nucleogenic particle

Naturally occurring. Dust or other particles which attract water vapor, causing rain or other precipitation to form.

Nucleonic particle

Artificially generated by crew. Produced by Federation replicators. Could refer to the nucleus of atoms.

Nucleonic radiation

Artificially generated by aliens. Exact nature unknown. It sounds like it is composed of nuclei, although it does have some biochemical effect.




Omega molecule in VOY: "The Omega Directive"
Artificially generated by aliens. A highly unstable molecule that can serve as a virtually inexhaustible power source.

Omicron particle

Naturally occurring. May be used as a power source.




Origin unknown. Used to power Akritirian ion-based drive systems, can be (as well as dilithium) converted to trilithium. Si-lithium, di-lithium, tri-lithium, para-lithium and even "lithium" itself, and none of these substances has apparently anything to do with the real-world element lithium. It's rather related to all of the above mentioned lithium-variants but silithium.

Submitted by Alex Hoffmann

Particle signature

Naturally occurring. A characteristic unique to each universe.


Artificially generated by crew. Medication used to manage Irumodic Syndrome. Not a cure.

Submitted by Fidel Melgoza


Naturally occurring. Used to regenerate environmental controls filters.

Update by Alex Hoffmann

Phospholipid fibers (unconfirmed)

Naturally occurring. An organic compound. In real life, phospholipids are fatty acids with phosphate groups attached. They are small and naturally occur only as liposomes and bilayer sheets, and as monolayer spheres called micelles. But they never form "fibers." Phospholipid bilayers are what cell membranes are mostly made of.

Photonic energy

Naturally occurring. Emitted from the surface of a protostar. A fancy name for light.


Naturally occurring or artificially generated by crew or aliens. Occurs in several gaseous phenomena. Used to distribute power on starships. A very hot, ionized gas. The atoms in plasma have enough kinetic energy that the electrons are torn from their nuclei, ionizing the gas.

Polaric ion

Artificially generated by aliens. Used as a power generation system.


Polaron beam in DS9: "The Search"
Artificially generated by crew. A particle with various exotic properties. In real-world condensed matter physics, a polaron is a type of mobile crystal defect consisting of an electron coupled to an induced lattice polarization. But this polaron, like the hole familiar from semiconductors, is only a quasi-particle that could be responsible for hardly any of the effects observed in Star Trek.


Artificially generated by crew. Structural material.

Submitted by Michael Warren


Naturally occurring. A particle. Real antimatter version of an electron.

Preanimate matter

Naturally occurring. Matter that is very close to being classified as a form of life, but doesn't quite make the grade.

Naturally occurring. Valuable mineral that glows with an internal light.


Protomatter reaction in DS9: "Second Sight"
Origin unknown. An unstable form of matter used by David Marcus as a shortcut in the construction of the Genesis Device.


Naturally occurring. An elementary particle. Positively charged baryon with a virtually infinite life span. Protons occur in all atomic nuclei.


Naturally occurring. An organic material. Makes up the interior of cells in living matter.


Naturally occurring. A neurotransmitter involved in telepathy.

Pulse compression wave

Naturally occurring. An elongated subatomic object, hundreds of meters long, but possessing almost no mass.


Artificially generated by crew. Used in thruster packs. This is the correct spelling of the substance previously listed as "corudum", according to the Fact Files.

Submitted by Alex Hoffmann



Radioactive radiation

Container with radioactive matter in TNG: "Thine Own Self"
Naturally occurring or artificially generated by crew. Collective term for different forms of radiation. The radioactive radiation consists of alpha rays (helium nuclei), beta rays (electrons) and gamma rays (electromagnetic rays). It occurs wherever nuclei of atoms fall apart (mostly "bigger" atoms like the ones of uranium). The technological ability of using the energy caused by nuclear reactions led to many inventions, like the nuclear power plant and the atomic bomb - inventions which changed our world in more than one way...

Submitted by Bird of Prey

"Red Matter"

Artificially generated by crew. Substance that initiates the formation of a black hole. This may be a nickname, owing to the substance's red color.


Artificially generated by crew. Used to improve eyesight.

Rhodium nitrite

Naturally occurring. Ore of inferior quality. Supplement by Bernd: Someone with better knowledge of chemistry may tell us if this compound would be viable.

Submitted by Alex Hoffmann

Riboviroxicnucleic acid

Naturally occurring. Like DNA, except the number of riboviroxicnucleic acid structures increase as the biological organism ages. In other words, without these structures, we wouldn't be able to "grow up."


Naturally occurring. A mineral.


Naturally occurring. Cast rodinium is the hardest substance known to Federation science.


Origin unknown. A non-toxic crystalline substance. This may have been supposed to be the real-world element rubidium, altered through a typo.
