Researchers develop nanosensor for faster E. coli detection

September 26, 2016

Researchers at Pittsburg State University in Pittsburg, KS, have developed a hybrid nanosensor to detect bacterial contamination from E. coli or other pathogens at concentrations as low as one colony-forming unit and to do it more quickly than existing methods.

The nanosensor uses a combination of magnetic relaxation and fluorescence measurements to both detect and quantify broad-spectrum contaminations in samples ranging from aquatic reservoirs to commercially produced food, according to an abstract posted Sept. 4 by the American Chemical Society in its ACS Infectious Diseases.

The method was developed by PSU Chemist Tuhina Banerjee, PSU Assistant Professor of Chemistry Santimukul Santra, and their colleagues Shoukath
