An optical chemical sensor based on a transparent membrane of polyelectrolyte complex (PEC), composed of alginate-chitosan membrane and 2,6-dichlorophenol-indophenol (2,6-DCPIP), coated on transparent mica was coupled with UV-Vis spectrophotometry and used for colorimetric measurements of ascorbic acid (AA). The transparent membranes of PEC were characterized using scanning electron microscopy (SEM) technique. The experimental parameters of the biosensor were optimized. Here, the optical chemical sensor showed maximum response at wavelength of 545 nm, with the optimum pH at 3. The calibration curve had a dynamic working range at 0.0 to 5.0 mM of AA with a limit of detection (LOD) of 0.13 mM AA. The membrane sensor has a long life time in the defined condition (4 o C). The developed optical chemical sensor correlated well with the standard method, HPLC for the determination of Ascorbic acid concentration in real samples.

“…113 There was no evidence of leakage of the reagents from the membranes and no drifts in the signal were observed for 7 and 5 h for CN -and ascorbic acid sensors, respectively. 90,91 The application of imidazolium ILs in the SAMs on gold surfaces in SPR sensors provided the native conformation of the proteins/enzymes in the course of their chemical immobilization to be maintained that resulted in greater catalytic activity than those for other surfaces. 50 Moreover, the use of a binary monolayer of the IL-biotin and 11-mercaptoundecanol significantly reduced the nonspecific adsorption of streptavidin and, consequently, improved the selectivity of its binding by the sensor's surface.…”

This paper reviews the primary literature reporting the use of ionic liquids (ILs) in optical sensing technologies. The optical chemical sensors that have been developed with the assistance of ILs are classified according to the type of resultant material. Key aspects of applying ILs in such sensors are revealed and discussed. They include using ILs as solvents for the synthesis of sensor matrix materials; additives in polymer matrices; matrix materials; modifiers of the surfaces; and multifunctional sensor components. The operational principles, design, texture, and analytical characteristics of the offered sensors for determining CO2, O2, metal ions, CN -, and various organic compounds are critically discussed. The key advantages and disadvantages of using ILs in optical sensing technologies are defined. Finally, the applicability of the described materials for chemical analysis is evaluated, and possibilities for their further modernization are outlined.
