Comparison of the stability of antigen-labeled Au@Pt@SiO₂ nanozyme and antigen-labeled HRP. a antigen-labeled Au@Pt@SiO₂ nanozyme and antigen-labeled HRP were treated at a wide range of temperatures between 20 and 80 °C for 3 h, and the peroxidase activity was measured under standard conditions. b antigen-labeled Au@Pt@SiO₂ nanozyme and antigen-labeled HRP were treated in media with a range of pH from 3 to 9 for 3 h, and then their peroxidase activities were measured under standard conditions
