"I need those nanites to create a delivery mechanism for the cure."
Samuel Sterns[src]

Nanites were objects that could be used for multiple purposes.


Unable to get accurate data from a sample of Bruce Banner's blood, Samuel Sterns asked Banner to find the source of the interference and move it out of range. Transforming into the Hulk, Banner found the jamming device that had been planted by the United States Armed Forces and threw it into a lake in Central Park. At this point, several Enclave soldiers appeared and killed the soldiers at the army barracks. They stole a drum of nanites and returned to their base.

Sterns soon contacted Banner and informed him that the radio waves concealed nanites and needed them to created a delivery mechanism for the cure that he was working on. Becoming the Hulk once again, Banner was informed by Rick Jones that the nanites had been loaded into a garbage truck somewhere in the city. The army were also seeking the nanite drum, but Hulk reached it first and returned it to Sterns at Empire State University.[1]
