Graphene is one of the new materials which has shown a large impact on the electronic industry due to its versatile properties, such as high specific surface area, high electrical conductivity, chemical stability, and large spectrum of electrochemical properties. The graphene material-based electronic industry has provided flexible devices which are inexpensive, simple and low power-consuming sensor tools, therefore opening an outstanding new door in the field of portable electronic devices. All these attractive advantages of graphene give a platform for the development of a new generation of devices in both food and environmental applications. Lipid-based sensors have proven to be a good route to the construction of novel devices with improved characteristics, such as fast response times, increased sensitivity and selectivity, and the possibility of miniaturization for the construction of portable biosensors. Therefore, the incorporation of a lipid substrate on graphene electrodes has provided a route to the construction of a highly sensitive and selective class of biosensors with fast response times and portability of field applications for the rapid detection of toxicants in the environment and food products.

“…The results of Raman and IR showed that the polymerization kinetics ended after four hours. The polymerization mechanism and generation of the signal was further on explored by Raman and IR spectroscopy, micro-Raman spectroscopy, DSC, and SEM experiments [2,3,9,10]. These membranes were stable for storage in air for a period of longer than two months.…”

Abstract:This review provides information and details about the fabrication of biosensors composed of lipid membranes that can be used to rapidly detect toxic compounds in food, environmental pollutants, and analytes of clinical interest. Biosensors based on polymeric lipid membranes have been used to rapidly detect a wide range of these analytes, offering several advantages including fast response times, high sensitivity and selectivity, portability for field applications, and small size. A description of the construction of these devices and their applications for the rapid detection of toxic substances in food, environmental pollutants, and analytes of clinical interest is provided in this review.
