Studies in the Area of Peroxidases Reported from Northeast Forestry University (Catalase Mimic Property of Co3O4 Nanomaterials with Different Morphology and Its Application as a Calcium Sensor)

By a News Reporter-Staff News Editor at Biotech Week -- Researchers detail new data in Enzymes and Coenzymes. According to news originating from Harbin, People's Republic of China, by NewsRx correspondents, research stated, "The applications of inorganic nanomaterials as biomimetic catalysts are receiving much attention because of their high stability and low cost. In this work, Co3O4 nanomaterials including nanoplates, nanorods, and nanocubes were synthesized."

Our news journalists obtained a quote from the research from Northeast Forestry University, "The morphologies and compositions of the products were characterized by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The catalytic properties of Co3O4 nanomaterials as catalase mimics were studied. The Co3O4 materials with different morphology exhibited different catalytic activities in the order of nanoplates > nanorods > nanocubes. The difference of the catalytic activities originated from their different abilities of electron transfer. Their catalytic activities increased significantly in the presence of calcium ion. On the basis of the stimulation by calcium ion, a biosensor was constructed by Co3O4 nanoplates for the determination of calcium ion. The biosensor had a linear relation to calcium concentrations and good measurement correlation between 0.1 and 1 mM with a detection limit of 4 mu M (S/N = 3). It showed high selectivity against other metal ions and good reproducibility."

According to the news editors, the research concluded: "The proposed method was successfully applied for the determination of calcium in a milk sample."
