Article Synopsis
- The rising interest in graphene derivatives stems from their diverse applications and potential oral entry into the population.
- This study examines the biotransformation and toxicity of reduced graphene oxide (rGO) through simulated digestion, revealing agglomeration during the process.
- Findings indicate that while undigested rGO is toxic to certain cells, digestion appears to mitigate toxicity, suggesting further research is needed on rGO's effects in the gastrointestinal tract.
The interest of graphene materials has increased markedly in the recent years for their promising applications in many fields as food packing. These new applications have caused some concern regarding their safety for consumers since the intake of these materials may increase. In this sense, a battery of in vitro test is required before its use as a food contact material.

The addition of functional groups by means of grafting strategies such as the sulfonation and the addition of nanoparticles such as graphene oxide (GO) were considered to bring new features to PVA. Two series of sulfonated and nonsulfonated composite nanofibers, with different compositions of GO, were prepared by electrospinning.
