Prussian blue nanoparticles have a stable structure and play an important role in in vitro diagnosis and disease therapy due to their unique enzymatic, optical, magnetic and other properties, attracting extensive attention from researchers. Traditional Prussian blue nanoparticles exhibit antioxidant activity, while cesium ion doping can induce a transition in the catalytic mechanism of Prussian blue nanoparticles, resulting in strong pro-oxidant activity.
Aladdin provides cesium-doped Prussian blue nanoparticles (Cs-PBNPs) with good dispersibility, surface functionalization, and strong enzyme-like activity, which can be effectively applied in in vitro diagnosis, tumor therapy, pollutant degradation, and other fields.
