“…This compound forms a pore, where the inner side is hydrophobic while the exterior is hydrophilic. A strong interaction between indoles and β-cyclodextrin has been demonstrated, showing promise for their incorporation to tailor the selectivity of colorimetric devices [ 27 ]. When CD was incorporated in the sensing mixture along with chromogenic dyes, the average signal response to indoles increased by 195%.…”

Paper-Based Multiplex Sensors for the Optical Detection of Plant Stress

The rising population and the ongoing climate crisis call for improved means to monitor and optimise agriculture. A promising approach to tackle current challenges in food production is the early diagnosis of plant diseases through non-invasive methods, such as the detection of volatiles. However, current devices for detection of multiple volatiles are based on electronic noses, which are expensive, require complex circuit assembly, may involve metal oxides with heating elements, and cannot easily be adapted for some applications that require miniaturisation or limit front-end use of electronic components. To address these challenges, a low-cost optoelectronic nose using chemo-responsive colorimetric dyes drop-casted onto filter paper has been developed in the current work. The final sensors could be used for the quantitative detection of up to six plant volatiles through changes in colour intensities with a sub-ppm level limit of detection, one of the lowest limits of detection reported so far using colorimetric gas sensors. Sensor colouration could be analysed using a low-cost spectrometer and the results could be processed using a microcontroller. The measured volatiles could be used for the early detection of plant abiotic stress as early as two days after exposure to two different stresses: high salinity and starvation. This approach allowed a lowering of costs to GBP 1 per diagnostic sensing paper. Furthermore, the small size of the paper sensors allows for their use in confined settings, such as Petri dishes. This detection of abiotic stress could be easily achieved by exposing the devices to living plants for 1 h. This technology has the potential to be used for monitoring of plant development in field applications, early recognition of stress, implementation of preventative measures, and mitigation of harvest losses.

“…CDs can form complexes with a wide range of molecules, including alkyl glycosides [125][126][127], chiral compounds [128][129][130][131][132][133], branched or cyclic alkyl groups [134,135], aromatic molecules [130,136,137], and proteins [138][139][140][141]. Interactions between cyclodextrins (host) and guest molecules may yield a stable complex with a high equilibrium constant; for example, β-CD forms a highly stable inclusion complexes with adamantyl derivatives with a binding constant of ~10 4 -10 5 M −1 [142,143] (See Table 6 for more examples).…”

Cyclodextrins: Structural, Chemical, and Physical Properties, and Applications

Due to their unique structural, physical and chemical properties, cyclodextrins and their derivatives have been of great interest to scientists and researchers in both academia and industry for over a century. Many of the industrial applications of cyclodextrins have arisen from their ability to encapsulate, either partially or fully, other molecules, especially organic compounds. Cyclodextrins are non-toxic oligopolymers of glucose that help to increase the solubility of organic compounds with poor aqueous solubility, can mask odors from foul-smelling compounds, and have been widely studied in the area of drug delivery. In this review, we explore the structural and chemical properties of cyclodextrins that give rise to this encapsulation (i.e., the formation of inclusion complexes) ability. This review is unique from others written on this subject because it provides powerful insights into factors that affect cyclodextrin encapsulation. It also examines these insights in great detail. Later, we provide an overview of some industrial applications of cyclodextrins, while emphasizing the role of encapsulation in these applications. We strongly believe that cyclodextrins will continue to garner interest from scientists for many years to come, and that novel applications of cyclodextrins have yet to be discovered.

“…Among the functional materials, β-Cyclodextrin (β-CD) has attracted particular attention, due to its unique availability, physic-chemical characteteristics and low cost [12]. The central cavity of cyclodextrins, which is lined with methylene hydrogens and glycosidic oxygen bridges, is relatively hydrophobic compared to water [13].…”

Abstract. An unique pretreatment and detection of rhodamine B in chilli sanples was described. The pretreatment method was based onβ-Cyclodextrin modified polystyrene (PS) nanofiber. The modified nanofiber obtained was studied by scanning electron microscopy and fourier transform infrared spectroscopy, respectively. The modified PS nanofiber extraction efficiency was higher than unmodified PS nanofiber.
