Iodide sensitive sensor based on a supported bilayer lipid membrane containing a cluster form of carbon (fullerene C60)

The iodide ion sensitivity of a solid-supported bilayer lipid membrane (s-BLM) containing buckminsterfullerene(C60) as an electron mediator has been investigated using the cyclic voltammetry technique. We have shown that C60 in a lipid bilayer environment produces a unique and simple system for the detection of iodide. The sensitivity of C60-containing s-BLM to I is excellent with a linear response in the range from 10(-8) to 10(-2) M. The use of fullerene C60-doped s-BLMs as sensors and devices for detecting other species is proposed.
