Biological receptors on the surface of cells function as sensors and mediators, which recognize molecules outside the cell and activate inside signal transduction pathways and, ultimately, cellular responses. These receptors have multivalent or cooperative binding sites, leading to highly specific molecular recognition through weak interactions based on hydrogen bonding, van der Waals interactions, etc. They are located in the cellular plasma membrane, the protective lipid bilayer that constitutes the critical barrier of the intracellular components to the extracellular environment. Cell membranes provide a unique platform to sense, respond to, and transduce signals and information. In these biological signaling processes, cooperativity is believed to play a crucial role, offering a mode of achieving selective recognition. The biochemical recognition processes that occur on the membrane surfaces form the basis of the most versatile and specific sensor systems known. By devising the capability of cellular membrane recognition systems, it may be possible to develop rapid, specific and biocompatible sensor systems. Furthermore, the intrinsic and unique functional plasticity of the specific receptor structures in the membrane suggests that synthetic access to artificial receptor in the membrane could lead to the development of controllable nanoscale architecture. Recently, the employment of lipid membranes in electronics such as field-effect transistor (FET) has attracted much attention in the development of sensor system due to the potentiality of superior biosensing and diagnostics tools in nanostructured devices. Here, we reports nanoelectronic sensors based on lipid membrane/single walled carbon nanotube FET hybrids incoprated with biolgical receptors.
