Laser and Optical Electronics Engineering Department grants MSC to the student Sarah Jammal for her thesis "Construction of a Laser Biosensor Based on the LMA-10 Fiber Mach-Zehnder Interferometer"
The student found that the presence of pregnancy hormone leads to increased refractive index of the urine sample and decrease the intensity of the laser beam outside. Through this test, a calibration of the biological sensor biosensor system was found to examine the pregnancy. Sensitivity to this sensor was 58.407ABS / RIU. In the blood test, the results showed that increased blood hemoglobin concentration increases the absorption of the blood sample of the laser beam. A calibration curve for the biosensor system was found to examine the hemoglobin concentration.
The sensor was also used to detect different types of anemia, such as anemia caused by iron deficiency and anemia. Different blood samples were taken for healthy people and samples for people with anemia. The results showed that the presence of anemia leads to an increase in the severity of the external beam. The sensitivity of iron deficiency anemia and anemia were 28.934ABS / RIU and 23.78ABS / RIU.
The discussion committee was chaired by Prof. Ziad Tariq Mahmood from Nahrain University Assc.Prof.Dr. Eyad Zouen Mohammed from the University of Technology, and Assc.Prof.Dr. Tahreer Safa from Baghdad University as members. Prof.Dr. Fareed Faris from university of technology and Lect.Dr.Layla Mohamed from Baghdad University as supervisors.
