About this collection

Guest Edited by Dr Run Zhang (The University of Queensland, Australia), Dr Songjun Zeng (Hunan Normal University, China) and Associate Professor Rona Chandrawati (University of New South Wales, Australia).

To address the challenges in the management of gases (including noxious gas and therapeutic gas), a series of nanoscale materials with fascinating structural, physical, and chemical characteristics have been developed for gas sensing and delivery in recent years. Specifically, nanosensors with a reliable, fast, sensitive, and specific response to target gaseous molecules or vapours are proved to be one of the most direct and effective tools for gas detection and identification. In biomedical and medicinal investigations, theranostic nanoparticles have shown great potential in shuttling drug-like gases (e.g. gasotransmitters, hydrogen, oxygen, etc.) to remote diseased sites for therapeutic purposes. This themed collection in Nanoscale Advances aims to provide a forum for recent trends in the rapidly evolving field of nanomaterials for gas sensing and delivery.
