Escherichia Coli
Research findings from J.O. Nagy et al update understanding of Escherichia coli
May 20th, 2008
"Shiga toxin-producing Escherichia coli organisms (STEC) were detected by Gal-alpha 1,4-Gal glycopolydiacetylene (GPDA) nanoparticles through the selective binding between Shiga toxin and GPDA nanoparticles," investigators in the United States report. "The binding produced a colorimetric change in the absorption wavelength of the GPDA nanoparticles," wrote J.O. Nagy and colleagues.

Nagy and colleagues published their study in Bioorganic & Medicinal Chemistry Letters...
