Biomed Gel

Bio med gel or biogel, designed to accelerate organic tissue's regeneration processes, was used in the biomedical field as a healing agent before the Great War. It is possible that the biogel used by the United States Armed Forces was based on the alien biogel.

Robobrains use the bio med gel as part of their internal repair systems. Although the organic brain inside the robot is a biological organism and cannot be repaired mechanically, a special reservoir filled with the gel is used to repair tissue damage, restoring the bot to combat functionality.

When a staff member of the Sierra Army Depot, General Clifton was wounded by an exploding attack mine, his damaged right eye was surgically removed and placed in Bio Med Gel by the medical staff, hoping that the eye would regenerate to the point where implantation would be successful. However, the Depot was evacuated before the surgery could commence. Evidently, the gel does work, seeing that Clifton's Eye repaired itself enough to be convincing to retinal scanners.

However when fully submerged in the same formula it had an unpleasant effect of dissolving Dobbs shortly after revival

When the Chosen One broke into the Sierra Army Depot, he used the gel as one of three components to complete a partially finished Robobrain. The other two components were a motivator (acquired from another brainbot) and a cybernetically enhanced brain which was procured from Level 4 bio-storage. After the activation, the brain acted as a storage medium for the Depot's resident AI.

Appearances in games
 only appears as an item in Fallout 2. It is mentioned in Fallout: New Vegas as the substance preserving Rex's brain, and his brain can be seen suspended in it.
