Student Activity: Toward a More Sustainable Campus through Innovative Design and Practical Application
Assist. Prof. Dr. Sewara J. Mohammed, a lecturer and researcher at Cihan University Sulaimaniya, recently authored a groundbreaking research article entitled “Ratiometric fluorescence detection of tetracycline in milk and tap water with smartphone assistance for visual pH sensing using innovative dual-emissive phosphorus-doped carbon dots” This significant contribution has been prominently featured by the reputable international publisher Elsevier, specifically in the Food Control. Food Control an impressive impact factor of 6 and holds a distinguished position in the first quartile (Q1), recognized by both Clarivate and Web of Science.
Tetracycline (TC) is a common antibiotic that poses risks to human and animal health when present in samples. pH is a crucial parameter for assessing water quality and food safety. In our research, we developed an innovative ratiometric probe using dual-emissive phosphorus-doped carbon dots (DE-P-CDs). These DE-P-CDs were synthesized through a green hydrothermal process. The probe demonstrated excellent analytical performance for detecting tetracycline (TC), with a limit of detection of 5.78 μM and 6.18 μM, respectively. Additionally, we employed the DE-P-CDs for visual pH sensing, where color changes indicated variations in pH levels: red to orange, green to dark green, and blue to dark blue. This visual observation facilitates easy assessment of pH . Furthermore, our method proved versatile, detecting TC in milk and tap water samples while maintaining outstanding environmental friendliness. Overall, our contribution lies in advancing analytical chemistry, food safety, and environmental monitoring.
