Abstract
- There is currently intense interest in the use of nanoparticles for a wide range of biomedical and technological applications. In this paper, the hierarchical Co doped ZnO nanoflowers were synthesized by a facile wet chemical method and explored as biosensing material. The as-modified novel hydrogen peroxide sensor exhibited a wide linear range (0.25–20 mM), highly reproducible response (R.S.D. of 2.7%) and long-term stability. The doping Co 2+ ions carried out the oxidations rapidly and efficiently for the catalysis of hydrogen peroxide (H 2 O 2 ). A high activity toward H 2 O 2 in the presence of ascorbic acid (AA) and NaNO 2 , which are only common for natural enzymes, has also been demonstrated. The good analytical performance, low cost and straightforward preparation method makes this doped semiconductor promising for a wide range of potential applications in medicine, biotechnology and environmental chemistry.
