Water Wire (IMAGE) Rensselaer Polytechnic Institute Caption Details of a water wire (central channel) embedded in a self-assembled immidazole channel (blue) in a lipid-bilayer. The summation of the incident visible (green) and IR (red) beams produce a resulting SFG (sum frequency generation) beam that characterizes the hydrogen bonding of the water wire at the molecular level (courtesy of Poul Petersen, Cornell University).
