Three-dimensional β-cyclodextrin functionalized graphene aerogels: An enhanced electrochemical sensing platform for quantification of Ponceau 4R

Two-dimensional material-based functional aerogels for treating hazards in the environment: synthesis, functional tailoring, applications, and sustainability analysis

“…Ma et al modified b-cyclodextrin (b-CD) onto GAs for electrochemical detection of carmine 4R in food. 123 The asprepared b-CD/GAs composites can recognize carmine 4R by host-guest interaction. In addition, there was an excellent (c and d) SEM images of MoS 2 @C 3 N 4 aerogels.…”

Recent Advances of Porous Materials Based on Cyclodextrin

“…The gifted detection range of β ‐CD modified graphene aerogel for Ponceau 4R is as wide as 1 × 10 ‐9 m –1 × 10 ‐6 m , and the detection limit reaches as low as 0.3 × 10 ‐9 m . [ 101 ]…”

Improved food additive analysis by ever-increasing nanotechnology

“…Thus, food colorants are essential for food manufacturing industry because they can excite the purchase interest of consumers. Many colorful compounds can be used as food colorants, including sunset yellow, allure red, lemon yellow, erythrosine, carmine, amaranth, tartrazine, acid orange, and so on [ 25 – 36 ]. In general, natural food colorants are harmless or even beneficial to the human body.…”

“…In addition to MWCNTs, other nanomaterials (bimetallic nanoparticles, transition metal oxides, graphene oxide, etc.) can also be used as good candidates for electrode modification and electrochemical activity enhancement [ 27 , 30 , 36 , 50 ]. For example, in order to detect amaranth in soft drinks, Wang et al .…”

“…The small relative standard deviation (3.5%, n π 7, three different electrodes) proves the high accuracy of the proposed method. In addition, the organic molecule β-cyclodextrin can also be used to modify the electrode to enhance the electrochemical detection in soft drinks due to its good adsorption capacity [ 36 , 53 ]. Although the most commonly used method for detecting colorants in soft drinks is to modify the working electrode with nanotechnology, in recent years, some methods other than electrochemical sensing have been reported to better detect colorants in soft drinks [ 54 – 57 ].…”
