Paper Abstract

Molecular recognition processes are very important in the investigation of biological phenomena as well as development of fiber optic biosensor. As promising materials, biofunctionalized polydiacetylene lipids have many special properties. p-10,12-pentacosadiyne-1-N-(3,6,9- trioxaundecylanide)-a-D-mannopyranoside (MPDA) was synthesized from 10,12-pentacasadiynoic acid (PDA). The mixed monolayer MPDA/PDA was prepared by using Langmuir- Blodgett technique on glass and optical fiber, respectively. Molecular recognition of Escherichia coli (E. coli) resulted in a change of the film color and can be quantified by UV- Visible absorption spectroscopy. The properties might be used for screening drugs and diagnosis.
