New themed collection on Xenonucleic acids (XNA)

We’re pleased to announce that a new themed collection from RSC Chemical Biology has now been published online.

Read the Collection

Guest-edited by Dennis Bong (Ohio State University), Philipp Holliger (MRC Laboratory of Molecular Biology), and Chaoyong Yang (Xiamen University), this themed collection covers all aspects of modified nucleic acids in chemical and synthetic biology including both in vitro as well as in vivo applications, and new chemistries. Taken together, the papers collected in this themed collection represent the state of the art on XNAs and highlights work at the interface of chemistry and biology.

A selection of the articles has been provided below. All articles in RSC Chemical Biology are open access and free to read.
