“…Overall, FeS 2 can be viewed as consisting of Fe 2+ and S 2 2− in a cubic symmetry with a slight distortion [ 31 ]. The band gap energy of bulk pyrite is 0.95 eV, and the optical absorption coefficient (5 × 10 5 cm −1 ) is high [ 32 ]; thus, pyrite has been found to exhibit semiconducting properties.…”

Recently, iron-based sulfides, including iron sulfide minerals and biological iron sulfide clusters, have attracted widespread interest, owing to their excellent biocompatibility and multi-functionality in biomedical applications. As such, controlled synthesized iron sulfide nanomaterials with elaborate designs, enhanced functionality and unique electronic structures show numerous advantages. Furthermore, iron sulfide clusters produced through biological metabolism are thought to possess magnetic properties and play a crucial role in balancing the concentration of iron in cells, thereby affecting ferroptosis processes. The electrons in the Fenton reaction constantly transfer between Fe2+ and Fe3+, participating in the production and reaction process of reactive oxygen species (ROS). This mechanism is considered to confer advantages in various biomedical fields such as the antibacterial field, tumor treatment, biosensing and the treatment of neurodegenerative diseases. Thus, we aim to systematically introduce recent advances in common iron-based sulfides.
