“…One of the approaches is based on the use of receptor units immobilized on an electrode surface to bind selectively analyte species, resulting in changes of interfacial properties (electrical, optical, piezoelectric, etc.) [85][86][87]. Further advances in the design of signal-responsive materials and their immobilization on solid supports [88,89] resulted in the new switchable electrodes reversibly activated and deactivated by chemical or biochemical signals [19,50].…”

IntroductionModified electrodes functionalized with various organic monolayers and thin films attached to their conducting surfaces have found numerous applications in electrocatalysis, sensors, and fuel cells [1][2][3][4][5][6][7]. Particularly, active research was directed to the applications of modified electrodes in different bioelectrochemical systems [8,9], including biosensors [10-13] and biofuel cells [14][15][16][17]. In the past decade, different modified electrodes functionalized with signal-responsive molecules [18], polymers [19], or supramolecular complexes [20] were developed to ''switch on demand'' electrochemical properties of electrode surfaces. Their applications in switchable biosensors [21], fuel cells [22], and electrochemical systems processing information [23] have been suggested. Various physical and/or chemical signals as well as their combinations were used to switch electrochemical properties of the modified interfaces between active and inactive states for specific electrochemical, electrocatalytic, and bioelectrocatalytic reactions. Light signals (irradiation of electrodes with visible or ultraviolet light) [24-31], magnetic field applied at electrode surfaces loaded with magnetic particles or magnetic nanowires [32][33][34][35][36][37][38][39][40][41][42][43], and electrical potentials producing chemical changes at the electrode surfaces [44][45][46][47][48] were used to reversibly alternate electrochemical properties of the modified electrodes. Chemical [29,[49][50][51] or biochemical [52] signals resulting in reversible changes of the interfacial properties were also used to switch the electrode activity ON/OFF for specific electrochemical transformations. The present chapter gives an overview of different signal-responsive electrochemical interfaces, emphasizing the importance of scaling up the complexity of the signal-processing systems and their applications in unconventional information-processing systems.

“…Owing to its unique structure, b-CD can easily form stable host-guest complex with certain organic molecules wherein the organic molecule fits into the hydrophobic cavity of b-CD [15,16]. Zhang et al used b-CD functionalized reduced graphene oxide hybrid nanosheets (b-CD-RGO) for separating and enrichment of DES: b-CD-RGO is a host-guest complex in which hybrid nanosheets of RGO get attached to the hydrophobic cavities of b-CD [8].…”

“…Molecular imprinting is a representative technique to memorize the shapes and functionalities of given molecules in matrices that include pre-designed recognition sites [6,7]. The matrix for imprinting has mostly been cross-linked polymers, and the imprinting effect was enhanced by the spatial fixation of functional monomer units that interact with template molecules.…”
