ClearGraphene-based Nanomaterials: Uses, Environmental Fate, and Human Health Hazards
This review examines graphene-based nanomaterials, which are used in medicine, agriculture, and industry, and finds that increasing human and environmental exposure raises safety concerns. The primary way these materials damage cells is through oxidative stress, similar to the mechanism seen with nanoplastics. While focused on graphene, the toxicity pathways described overlap with those triggered by micro- and nanoplastics, offering insight into how tiny engineered particles broadly affect human health.
