This article presents a survey of some of the main research on the development of self-replicating loops. The defining feature of these cellular automata is their ability to create identical copies of themselves by constantly executing a set of instructions dynamically stored within their structure. Interest in these structures has grown in recent years as a possible solution to tackle some of the issues relative to the introduction of next-generation molecular scale electronics.
