An artificial glycolipid was designed and applied to quartz crystal microbalance technique for the detection of verotoxins produced by highly toxic bacteria: Escherichia coli O-157. We have successfully detected both types of verotoxins (type-1 and 2) within 30 – 40 min in crude sample solutions and to determine the binding constants, associate and dissociate constants.
