Iranian researchers produced electromagnetic nanocomposite made of iron oxide and polyfuran magnetic nanoparticles and succeeded in the synthesis of electrochemical biosensor sensitive to hydrogen peroxide.
By producing the sensor, the researchers overcame some problems, including low conductivity and low thermal stability of polyfuran.
Cardiac disorders increase hydrogen peroxide in body’s tissues, which damages inner layer of arteries and causes blood coagulation and heart and brain attacks. Therefore, it is very important to measure hydrogen peroxide in body tissues and biological liquids such as plasma. Taking into account the fact that the number of deaths caused by cardiovascular diseases is increasing in the country, it is vital to present a simple, fast and effective method for the measurement of hydrogen peroxide concentration to prevent the loss.
Dr. Mehdi Baqayeri, one of the researchers, explained about the importance of this research, and said, “In addition to determination of hydrogen peroxide concentration in order to prevent cardiovascular diseases, we need to measure the amount of hydrogen peroxide in rainwater for the preparation of drinking water. In some parts of the world, including Australia, rainwater is used to provide drinking water due to the shortage in water reservoirs. The amount of hydrogen peroxide in rainwater somehow determines the toxicity, solubility, biocompatibility and even concentration of metals in rainwater.”
Among the advantages of this research, mention can be made of high compatibility, selectivity, sensitivity, low cost, no need for difficult pre-preparation steps and no harm to the sample.
Results of the research have been published in Sensors and Actuators B: Chemical, vol. 202, 31 October 2014, pp. 1200-1208.
