However, significant pi-pi stacking across layers causes graphene to combine and form a hydrophobic compound. To address this issue, graphene is usually oxidized via the Hummers process, resulting in the creation of graphene oxide. Related StoriesHowever, the Hummers technique creates gases with high nanotoxicity, such as nitrogen dioxide and dinitrogen tetroxide. Several changes, commonly known as the modified Hummers techniques, have been explored to lower the nanotoxicity and boost the productivity of the Hummers process.
Important Applications of Graphene Oxide In recent years, graphene oxide and its derivatives have emerged as exceptional carbon-based materials with catalysis, biomedicine, and tissue engineering applications. Graphene oxide has also shown promise in numerous tissue engineering domains, including the regulated development of stem cells and the release of active biological agents from stem-cell-containing delivery platforms.
According to the present research, the most significant nanotoxicity pathway of graphene oxide is the formation of reactive oxygen compounds in target cells. More research is needed to better characterize the nanotoxicity mechanisms, particularly those focusing on the biological interactions of graphene materials with cellular membranes.
