1. Abstract
Based on the fact that if present graphene in vials of nanolipids of biopharmaceutical the aspects must to be coloured the reported findings by some independet researcher of graphene like particle in viasl of m Rna covid-19 vaccine seem to suggest that this impurity can be present only inside the nanolipids. The production for this encapulated biotecnological product imply the mixing of an acqueos phases (mRna) with an lipidic phases (nanolipids).
