Electrochemical receptor operation

Receptor Action In Analytical Membranes. This work has Identified the Importance of some of the relevant parameters associated with organized lipid matrix ion conduction. Receptors embedded In these matrices should function to perturb one or more of the three compartmenta 1 zones of the BLM. A number of features significant to electrochemical receptor operation follow ... 

Unfortunately, these aza-ethers showed limited solubility in the polar solvents that are typically preferred in nonaqueous electrolytes, and the electrochemical stability window of the LiCl-based electrolytes is not sufficient at the 4.0 V operation range required by the current state-of-the-art cathode materials. They were also found to be unstable with LiPFe. Hence, the significance of these aza-ether compounds in practical applications is rather limited, although their synthesis successfully proved that the concept of the anion receptor is achievable by means of substituting an appropriate core atom with strong electron-withdrawing moieties. 

Figure 9.1 A general scheme of ligand-receptor contact interaction. The operation of an electrochemical biosensor which is based on the properties of a modified BLM or s-BLM. L, ligand (substrate, antigen, hormone, ion or electron, donor or acceptor) R, receptor (enzyme, antibody, receptor site, carrier or channel, acceptor or donor).

Chemical sensors can be of gas, liquid, and solid particulate sensors based on the phases of the analyte. Depending on the operating principle of transducer in a chemical sensor, it can be used as optical, electrochemical, thermometric, and gravimetric sensor. Chemical sensors also include a special branch referred to as biosensors for the recognition of biochemicals and bio-reactions. The use of biological elements such as organisms, enzymes, antibodies, tissues, and cells as receptors differentiates biosensors from conventional chemical sensors.
