Nanochips (also known as Microchips) are living alien objects used in Ben 10: Alien Swarm by the hive.
The Nanochips are tiny, mechanical insects. They are yellow/orange/red in Alien Swarm, but are blue in Ultimate Alien.
The Queen produces Nanochips from her body, and after she takes up residence in Victor Validus' body, she produces them from there. They have the ability to take over a person's mind, making that person completely subservient to the Queen's will. They are a hybrid which is part organic matter and part machine as pointed out by Kevin. The Queen was destroyed by Nanomech.
The Nanochips surprisingly returned in Revenge of the Swarm. The team discovered that the Nanochips took over Elena Validus' mind and had made her the Queen of the Hive. After Elena sacrificed herself for Ben by destroying her Nanochip self, the chips still had some life in them.
They re-appeared in The Perfect Girlfriend, in which it was revealed that Elena and the nano chips were still alive.
