Abstract Sepiolite is a nanofibrous natural silicate that can be used as a nanocarrier for DNA transfer thanks to its strong interaction with DNA molecules and its ability to be naturally internalized into mammalian cells through both non‐endocytic and endocytic pathways. Sepiolite, due to its ability to bind various biomolecules, could be a good candidate for use as a nanocarrier for the simultaneous vectorization of diverse biological molecules. In this paper, we review our recent work, issued from a starting collaboration with Prof. Ruiz‐Hitzky, that includes diverse aspects on the characterization and main features of sepiolite/DNA nanohybrids, and we present an outlook for the further development of sepiolite for DNA transfer.
