Nanites are nanotechnology that can be used to briefly affect an individual's biological systems, especially a meta-human's, such as disable a speedster's connection to the Speed Force for a limited time. It was created by Ray Palmer sometime between 2014 and 2015.
When a speedster is injected with nanites, he partly loses his connection to the Speed Force for a limited time, disabling his ability to move at super speed.
However, nanites can be disabled by the injected speedster if he vibrates his body at an incredible speed.
In 2015, at Barry Allen's request, Oliver (as Al Sah-him) came to Central City to help the Flash and Firestorm defeat the Reverse-Flash. During the fight, knowing that he can't beat the evil speedster moving at super speed, Oliver shot Reverse-Flash with a Trick arrow filled with nanites, temporarily disabling his powers. He then explained to the speedster what it was before fighting him hand-to-hand. However, Reverse-Flash eventually managed to vibrate his body fast enough to disable the nanites, thus giving him the ability to run again and attack the archer.
Months later, in order to defeat Zoom, Harrison Wells created a speed-dampening serum out of the nanites Oliver used. When Barry fought the demonic speedster, he tried to inject him with the serum, but couldn't catch up to Zoom's incredible speed. Later in the fight, when Zoom was about to hit Barry with a lethal strike, Wells tried to shoot him using a dart containing the serum, but the speedster easily caught it and used it on Barry instead, thus temporarily disabling his speed.
In 2018, after Iris West-Allen made Oliver (whom she believed to be Barry due to the reality change) faint by putting something in his drink, she jokingly stated, "Nanites; courtesy of Ray Palmer," the same thing he said while fighting Reverse-Flash three years prior.
Behind the scenes
- The phrase "Nanites, courtesy of Ray Palmer," said by Oliver Queen in "" became an internet meme. Iris West-Allen quoting it again in "" was a clear reference to the meme.
