Overview
Graphene oxide (GO) is a nanomaterial with significant bioeffects that require active detoxification through oxidative degradation.
Biochemical Properties
- Semiconductor behavior: Holey rGO acts as a potent semiconductor, requiring complete oxidation for safe elimination
- Multilayer structure: GO exists as multilayer graphene polymers requiring basal layer disruption
- Xenobiotic classification: GO is classified among mutagenic and teratogenic xenobiotics that affect gene expression across generations
Degradation Pathway
1. HRP initiation: Horseradish peroxidase creates holes in the basal plate level
2. H2O2 oxidation: Hydrogen peroxide from mitochondria and immune cells oxidizes holey rGO residues
3. MPO enhancement: Myeloperoxidase produces HOCl for complete degradation
4. Final products: Harmless CO2 and H2O
Exercise Synergy
Aerobic activity increases mitochondrial H2O2 production through electron transport chain leakage, providing the oxidative "combustion" needed to degrade holey rGO completely.
