RNA is used to purify carbon nanotubes (CNTs) in a simple, two‐step method that does not require a time‐intensive process or harsh chemical or physical treatments. The purity of the RNA‐purified CNTs is demonstrated by a variety of physical characterization methods such as AFM (see figure), confirming that treatment of the RNA‐wrapped CNTs with ribonuclease A effectively removes the RNA, allowing subsequent recovery of pure CNTs.
