Prof. Dr. Shatha Abdul Wadood, the late Prof. Dr. Abdul kareem Al-Sammarraie and the lecturer Dr. Ali Saad Aliwi from the department of chemistry at the college of science, has received a patent for their study entitled “Biosensor Design of Hydrogen Peroxide by Restricting the Hemoglobin Protein on the Working Carbon Electrode Imprinted on a Chip and the Axis with Butane and Silver Nanoparticles Material” after the fulfillment of all requirements for obtaining patents from the Central Organization for Standardization and Quality Control.
The study dealt with the use of the hemoglobin protein as a biocompound, which works to solve the problem of interference in the measurement and estimation of hydrogen peroxide electrochemically by the presence of certain compounds in the sample by changing the reduction voltage, as well as the use of silver nanoparticles that increase the surface area of the electrode of a chip containing three Screen Printed Carbon Electrode which increases its adequacy. The results showed that the designed sensor is having a high analysis speed of hydrogen peroxide in biological samples with high adequacy, a linear response to low concentrations, high stability, the possibility of analyzing very small samples up to (10ml) and ease of use, so it is being a suitable sensor in estimating H2O2 in many areas.
