Biogenic weapons in liquid form

Biogenic weapons, bioweapons, or biogenic devices were a classification of weapon that caused little or no damage to starships or infrastructure, but instead were designed to biogenically interfere with lifeforms, most commonly to attack people. This category included genetically-engineered viruses, poisonous chemical compounds, and other similar materials. Examples of biogenic weapons included cobalt diselenide, which was deadly to Cardassians, and trilithium resin, which was deadly to Humans. (DS9: "For the Uniform")

Bio-mimetic gel could be used to make biogenic weapons when combined with retroviral vaccines. (DS9: "In the Pale Moonlight"; TNG: "Preemptive Strike")


One of the options pursued by the Xindi for the destruction of Humanity was a deadly bio-weapon, which they attempted to unleash on Earth in the year 2004. (ENT: "Rajiin", "Carpenter Street")

The Harvesters, developed by the T'Lani and the Kellerun, were nanobiogenic weapons. (DS9: "Armageddon Game")

In 2373, while in the employ of Hagath and Gaila, Quark claimed he'd arranged to procure a quantity of Varaxian LM-7, an experimental biogenic weapon that could wipe out millions of people within the space of a week. (DS9: "Business as Usual")

The Dominion was known to use biogenic weapons as well. One example is the Teplan blight, a virus that afflicted the people of the Teplan system when they resisted the Jem'Hadar. (DS9: "The Quickening", "Inter Arma Enim Silent Leges")

The Maquis gained possession of biogenic weapons after capturing the cargo of several freighters. Michael Eddington used them in attacks on Cardassian planets in the Demilitarized Zone until he was stopped by Benjamin Sisko. Several months later, Sisko was concerned the remaining Maquis biogenic weapons could have been placed on cloaked missiles. (DS9: "For the Uniform", "Blaze of Glory")

Thalaron radiation had biogenic properties that made it useful as a weapon. The Reman warbird Scimitar was designed to emit thalaron radiation as a biogenic weapon capable of destroying all life on a class M planet. (Star Trek Nemesis)

The Federation generally disapproved of the use of such weapons. (DS9: "For the Uniform")

In The Voyager Encounter holoprogram, The Doctor designed biogenic weapons for the warship Voyager to use against the Kyrians. His bioweapons resulted in eight million casualties during the Great War. (VOY: "Living Witness")

In 2377, the Lokirrim accused the crew of the Delta Flyer of manufacturing viral weapons, after discovering biomatter onboard that The Doctor had been studying. (VOY: "Body and Soul")

According to the script for "Blaze of Glory", the pronunciation for biogenic was "bi-oh-GEN-ik". [1]
