Omowunmi Sadik




A core objective of Omowunmi Sadik's research program is to understand the mechanism of the transduction of chemical information at interfaces, and to use this knowledge in the pursuit of innovative biosensing technologies, functional materials and devices. A sensor is a device that responds to physical, chemical or biological quantity, and converts that quantity into a signal or an output. The driving force behind her biosensor research is the need to build sensor systems that quantitatively measure target species in a complex system. Omowunmi Sadik has developed innovative biosensors for ultrasensitive detection of Staphylococci Enterotoxin B (SEB), biofilm, nucleic acids, pain biomarkers, oral proteins, E. coli, Bacillus globigii, chromium VI, polychlorinated biphenyls, environmental pollutants and toxic metals. Aside from biosensors, She has also established a world-class research in conducting polymers and biodegradable membranes. Examples include polyphenols, polyamic acid nanomembranes, polyoxy-dianilines, and sequestered metal nanoparticles within electroconducting polypyrrole. She has been recognized for her research and development of nano-bioanalytical detection platforms for environmental and biological monitoring. Her team's current sensors incorporate transducers that use complementary physical, chemical, and biological phenomena to measure orthogonal characteristics of chemical or biological species of interest.
