Abstract
Surfactants useful for enhancing the electrical conduction of electrodes attached to the surface of a patient. The surfactants are also useful in transport of materials in and out of the body of a patient (animal or human) and in the measurement of disease states. Typical surfactants particularly useful in the invention are broadly represented by protein/fatty acid based compounds. The protein/fatty acid compounds may be lipopolypeptides. In some embodiments the lipopolypeptides may be acyl peptides. Typical acyl peptides are Lamepon S™, MayTein C™ and MayTein CT™.
