Immunological detection of hepatocellular carcinoma biomarker GP73 based on dissolved magnetic nanoparticles

- The peroxidase-like activity of DMNPs is higher than WMNPs.
- DMNPs demonstrated the same change trend as standard ferric ion solutions.
- DMNPs were successfully applied in the detection of GP73.
- The method based on DMNPs is more sensitive than the method based on WMNPs.
