Graphene is considered the ultimate material for applications in many fields, from electronics to composites and biosensors. Biological studies on graphene and graphene oxide are also currently underway in many laboratories for two main aims: (i) the exploitation of the graphene properties in biological applications; (ii) the assessment of the potential toxicity of graphene layers.Graphene is usually prepared by the renowned scotch tape technique or by CVD processes. As such, graphene cannot be dispersed in water of biological media, owing to its complete insolubility. Novel ways to prepare dispersible graphene in water are very much needed. Ball milling of graphite in the presence of melamine has been found in our labs to be a method of choice to exfoliate graphite and generate dispersions of graphene in many solvents, including water.During this talk, we will discuss (i) optimized ways to generate graphene in solvents using ball milling; (ii) the use of graphene in polymer composites for drug delivery purposes; (iii) studies of interaction of so-prepared solutions with cells.
