Abstract/OtherAbstract:
Dumbbell-like Pt(48) Pd(52) -Fe(3) O(4) nanoparticles are synthesized and functionalized with oleylamine-polyethyleneglycol to serve as an efficient catalyst for H(2) O(2) reduction and tetramethylbenzidine (TMB) oxidation in biological solutions. The Pt(48) Pd(52) -Fe(3) O(4) /TMB kit is even more active than the natural enzyme for H(2) O(2) detection with a detection limit reaching 2 μM, and is successfully used to quantitatively monitor the extracellular H(2) O(2) generated by neutrophils.
