Graphene oxide is known to cause:
cardiotoxicity (1),
may function as an electrochemical biosensor (2) using radio frequency or microwaves (3) to detect certain chemicals in the body (4,5).
Its use in drug delivery has shown to create a cytokine storm immune response (6),
facilitates drug delivery across the BBB (Blood Brain Barrier) (7), and may cause cellular changes such as increased neuronal firing (8).
Interestingly, it may be used in Electromagnetogenetics as a basis for mind control (9,10).
Graphene nano particles have unique physical, electrical, and chemical properties, and the biological applications are far-reaching.

Safety Assessment of Graphene-Based Materials: Focus on Human Health and the Environment
Abstract
Graphene and its derivatives are heralded as “miracle” materials with manifold applications in different sectors of society from electronics to energy storage to medicine. The increasing exploitation of graphene-based materials (GBMs) necessitates a comprehensive evaluation of the potential impact of these materials on human health and the environment. Here, we discuss synthesis and characterization of GBMs as well as human and environmental hazard assessment of GBMs using in vitro and in vivo model systems with the aim to understand the properties that underlie the biological effects of these materials; not all GBMs are alike, and it is essential that we disentangle the structure–activity relationships for this class of materials.
