Abstract
- Abstract 2D MXenes find applications in several technology fields. Solution processing techniques can facilitate the integration of these materials within the technological supply chain. Here, a highly concentrated (up to 1.5 g L−1) and stable dispersion of 2D Ti3C2Tx MXene flakes is produced by an environmentally friendly liquid phase exfoliation process (LPE) in dihydrolevoglucosenone (Cyrene). The flakes preserve their elemental composition after 6 months, while those exfoliated in N‐Methyl‐2‐pyrrolidone (NMP), a commonly used solvent, undergo significant oxidation. The cytotoxicity of the MXene flakes in Cyrene and in NMP is investigated by assessing the cellular viability in a human keratinocyte (HaCaT) cell line, which is a relevant model for skin applications. The data show that the MXene flakes in Cyrene induce cytotoxic effects for a dose > 1 µg cm−2, as similarly observed for the MXene flakes in NMP. Efforts are made to overcome this by collecting the MXene flakes and redispersing them in a solution of bovine serum albumin (BSA). MXene in BSA does not affect cellular viability and cell morphology, possibly due to the formation of a protective protein corona around the individual MXene flakes. These findings illustrate an environmentally friendly strategy to produce biocompatible 2D MXene for biomedical applications.
