Liquid hydrogen peroxide is difficult to control and inconvenient to use. A solid hydrogen peroxide source can solve this problem. Aladdin provides Zinc Peroxide Nanoparticles, approximately 40‑50 nm in size, with good solubility. In an acidic aqueous environment, they decompose to produce hydrogen peroxide and a small amount of oxygen. They are widely used in biomedical fields such as tumor therapy, bacterial infection therapy, and biosensing in combination with nanozymes.
