“…On the other hand, quite recently, Badiei and co-workers have established a β-CDbased cross-linked polymer, the CD-nanosponge (62) with pyromellitic anhydride (61) cross-linker for the selective and sensitive detection of diclofenac among various other interfering analytes, such as ibuprofen, morphine, amphetamine, and codeine (Figure 17) [77]. For diclofenac, they have observed a detection limit of 0.92 μM and linear range of 1À33 μM.…”

Owing to the selective recognition ability, exceptional biocompatibility, water solubility, non-toxicity, economically inexpensive, commercial availability, and easy functionalization, cyclodextrins (CDs) act as the main building blocks for the creation of beautifully simple yet much effective supramolecular architectures of fundamental interest. Over the past few decades, CDs have engrossed a noteworthy interest in the scientific community because of their usage in the development of chemical sensors via molecular recognition phenomenon. Bearing the delightful sensing capability of CDs in mind, herewith, we envisioned to disclose the recent developments in the sensing of diverse biologically significant small molecules by CDs through colorimetric, fluorescence, electrochemical, and potentiometric response. Sensing events and corresponding distinguishing optical features in cyclodextrin-based monomers, dimers, clusters, and nano-assemblies have been elaborated in detail. The authors are of the opinion that this chapter will offer new dimensions to supramolecular sensors in general and CDs-based sensors in particular.

“…In the case of using dianhydride linkers alone or with 2-hydroxyethyl disulphide ( Daga et al, 2016 ), the addition of triethylamine (Et 3 N) as basic catalyst is required, and the exothermic reaction occurs quickly at room temperature ( Nazerdeylami et al, 2021 ; Suvarna et al, 2021 ; Yazdani et al, 2021 ). Using other linkers, such as HDI ( Yazdani et al, 2021 ), MDI ( Khajeh Dangolani et al, 2019 ), DMC and DPC ( Singh et al, 2018 ), Et 3 N can also be introduced to increase the rate of the reaction, with or without an increase in temperature.…”

“…The polymeric material has an heterogeneous size distribution with a high polydispersity index. It presents an excellent selectivity for diclofenac (LOD 0.92 µ M) in aqueous solution and tablets, whose value is not significantly influenced by the presence of different drugs, probably due to more hydrophobic behaviour of the diclofenac ( Nazerdeylami et al, 2021 ).…”

Cyclodextrin-Based Nanosponges: Overview and Opportunities

Nanosponges are solid cross-linked polymeric nano-sized porous structures. This broad concept involves, among others, metal organic frameworks and hydrogels. The focus of this manuscript is on cyclodextrin-based nanosponges. Cyclodextrins are cyclic oligomers of glucose derived from starch. The combined external hydrophilicity with the internal hydrophobic surface constitute a unique “microenvironment”, that confers cyclodextrins the peculiar ability to form inclusion host‒guest complexes with many hydrophobic substances. These complexes may impart beneficial modifications of the properties of guest molecules such as solubility enhancement and stabilization of labile guests. These properties complemented with the possibility of using different crosslinkers and high polymeric surface, make these sponges highly suitable for a large range of applications. Despite that, in the last 2 decades, cyclodextrin-based nanosponges have been developed for pharmaceutical and biomedical applications, taking advantage of the nontoxicity of cyclodextrins towards humans. This paper provides a critical and timely compilation of the contributions involving cyclodextrins nanosponges for those areas, but also paves the way for other important applications, including water and soil remediation and catalysis.

“…4,5 At present, detection methods for DCF include high performance thin layer chromatography, 6 high pressure liquid chromatography, 7 gas chromatography 8 and fluorescence sensing. 9 Among these methods, it is well known that luminescence analysis has become a more and more popular technique owing to its simple instrumentation, high sensitivity and wide linear range. [10][11][12] In addition, due to the excellent reproducibility, simplicity and rapidity of the luminescence method, luminescent sensing materials have great potential to be developed into detection devices for point-of-care testing (POCT).…”
