ALEXANDRIA, Va. – ERDC Topographic Engineering Center’s (TEC) Dr. Clint Smith, Fluorescence Spectroscopy Laboratory, recently co-authored an article regarding biosensors and technical expertise in the analysis of biosensor architectural support in Sensors and Transducers, volume 137, issue 2.
The article "Rapid Detection of Escherichia coli O157:H7 Using Competitive Exchange of Fluorescent Surrogate Modified Surfaces in Liquid Media," was co-authored with Dr. Evangelyn Alocilja of Michigan State University (MSU); Michael Anderson, a Science, Mathematics and Research for Transformation doctoral student at MSU; and TEC’s Andmorgan Fisher and Alex Ly.
The article cites a novel fluorescent surrogate based immunosensor that is presented for use in remote detection of Escherichia coli O157:H7. It describes the successful generation of a sensor comprised of fluorescent surrogates with attachment to covalently immobilized antibodies. The sensor design is adaptable for integration into remote sensing-type systems due to its low power requirements, and stability. Future uses include the integration of communication equipment and testing in natural water bodies.
