About this collection
Metal-organic Frameworks (MOFs) first captured the interest of the scientific community due to their remarkable gas adsorption properties. Subsequently, the scope of MOF chemistry swiftly expanded as researchers continued to explore and uncover new applications for these versatile materials. This Editor’s collection, guest edited by Associate Editor Christian Doonan, highlights recent contributions to CrystEngComm that are broadly focussed on bio-applications of MOFs. The selection of articles showcases the wide range of topics where MOFs are being employed to address research challenges and questions in biological science including, cellular imaging, drug delivery and release, chemical sensing, and biocatalysis. While MOFs are the common link between these studies the core concepts of crystal engineering feature prominently and thus point towards the richness and diversity of this area of chemistry.
