7683 446 Au@Co-Fe NPs 25 nm TEM The TEM image also confirmed that Au@Co-Fe NPs are spherical and about 25 nm. 253 U/mg The Au@Co-Fe NPs activity (units) calculated based on the Eq. 4:(4)bnanozyme=Vε×l×(ΔAΔt) In the Eq. 4, b nanozyme is the catalytic activity of Au@Co-Fe NPs defined in units. V is the total volume of reaction solution (μl), ε is the molar extinction coefficient (39,000 M−1 cm−1) of the oxidized TMB, at 652 nm, l is the path length of light traveling in the cuvette (cm), A is the absorbance after subtraction of the blank value and ΔA/Δt is the initial rate of change in absorbance at 652 nm min−1.
