The extensive research on Liquid-Phase Exfoliation (LPE) over the last 10 years has enabled a low cost and mass scalable approach to the successful production of a range of solution-processed 2-dimensional (2D) materials suitable for many applications. However, direct LPE requires the use of specific solvents, which are typically toxic and expensive. Non-covalent functionalization of 2D materials is therefore an attractive approach enabling to perform LPE of 2D materials in water.<br/><br/>In this talk I will give an overview on the process of LPE assisted by pyrene derivatives, showing that these molecules can provide the production of defect-free, stable and highly concentrate 2D material inks in water, which can be used in printed electronics and bioelectronics. Furthermore, the supramolecular receptors introduced during LPE can be used to carefully tune the surface properties, hence enabling to design the material for biomedical applications and sensing.
