“…Since the discovery of planar, Plateau‐Gibbs border‐supported bilayer (black) lipid membranes (BLMs) separating two aqueous solutions in the early 1960s, this biomembrane mimicking system has been extensively studied in an attempt to apply it toward desired basic and practical utilization (2, 25). Since then numerous studies have been carried out with such a system, some of the most recent studies involving doping of BLMs with, for example, azo pyridinium with a large lanthanide complex counterion or metallochlorophylls for photoelectric response (57, 58, 108), spiropyran alkyl chain substituted derivatives for the purpose of photochemical regulation of their electrical properties (59) or azobenzene derivatives for the regulation of “quasi‐channels” incorporated in the membrane (60). The use of BLMs as a sensor for the direct electrochemical detection of some toxins, like aflatoxin M 1 (61), has also been reported, as well as electrochemical studies of electron‐transfer processes across BLMs mediated by the ubiquinone 10 (62) or TCNQ (tetracyanoquidodimethane) (46).…”

Supported bilayer lipid membranes (BLMs) and lipid monolayers have been known for quite sometime and are attracting sustained interest since they open new research vista and offer practical approaches in biosensor development and molecular device applications. Central to these areas of interest are electric processes and redox reactions where the movement of ions and electrons plays a pivotal role. In this paper an overview of the major findings in this field is presented. Further, we summarize the work on planar lipid bilayers and monolayers that have been done in the past few years in a number of laboratories. Supported planar BLMs and their closely related systems provide the foundation for a variety of lipid bilayer-based molecular sensors that are sensitive, versatile, as well as potentially inexpensive (i.e., disposable), and open to all sorts of experimentation.
