A cloning vector is a small piece of DNA, taken from a virus, a plasmid, or the cell of a higher organism, that can be stably maintained in an organism and into which a foreign DNA fragment can be inserted for cloning purposes. In the context of nanotechnology, cloning vectors are crucial for the manipulation of genetic material at the nanoscale, which can be used for various applications, including gene therapy, synthetic biology, and biomedical engineering.
