Application


  • Electrochemical detection applications: A study on La-based perovskites incorporated with functionalized carbon nanofibers highlights the use of arsenic trioxide for the electrochemical detection of roxarsone in water and food samples, providing a method to improve safety and environmental monitoring (John Felix MA et al., 2024).

  • Antiproliferative effects in cancer research: Research demonstrates the inhibitory effects of arsenic trioxide, combined with metformin, on KG1a cell proliferation, suggesting its potential utility in developing antineoplastic strategies (Huang-Li WH et al., 2024).

  • Environmental remediation: A review on manganese oxide-based materials for arsenic removal discusses the application of arsenic trioxide in environmental remediation, focusing on the effectiveness and advancements in arsenic decontamination technologies (Younas M et al., 2024).

General description

Arsenic(III) oxide (ATO) is an inorganic form of arsenic that is used as a therapeutic compound for treating patients with acute promyelocytic leukemia (APL). Many drug-delivery methods are currently being developed using nanotechnology to overcome its poor bioavailability due to rapid clearance from blood.
