Biosensor for determining bacterial contamination - an alternative for prevention and early detection of bacterial infections
PhD defence, Wedensday, 10 May 2023. Rimsha Binte Jamal
During her Ph.D. studies, Rimsha Binte Jamal developed novel biosensors for the early and rapid detection of bacterial contamination, which is responsible for food-borne illnesses and infectious diseases. The current methods of microbial culture and PCR tests need a minimum of 12 h waiting time, are costly, and require a large number of bacterial cells to provide a definite answer. These inherent issues make matters worse in the case of bacterial infection, where immediate detection and care are critical. Rimsha addresses these issues by developing biosensors that are based on a cost-effective platform and can detect bacterial RNA and whole cells at levels as low as 2 - 10 bacteria, within 30 minutes.
The developed biosensors demonstrate the true potential of resolving the problem of delayed contamination detection and thus preventing food-borne illnesses and infectious diseases.
The Ph.D. study was completed at the Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.
This summary was prepared by the Ph.D. student.
