“…Current applications focus on site-specific drug/gene delivery and protein separation and analysis. Considering the avant-garde developments in CD chemistry, glycobiology and nanotechnology, a much broader range of progress is expected in the near future from their synergistic blend, including fields as diverse as catalysis [199,200], bioremediation [201], sensing [202][203][204][205], diagnostics [206,207], theranostics [208,209], vaccines [210,211] or personalized medicine [212,213]. Structures and schematic representation of the strategy developed by Riela, Lazzala and coworkers to assemble hybrid glycoCD/halloysite nanotubes to achieve functional glyconanomaterials for the co-administration of curcumin (Cur) and silibinin (Sil) in thyroid cancer cells [196,197].…”

Cyclodextrins (CDs) have long occupied a prominent position in most pharmaceutical laboratories as “off-the-shelve” tools to manipulate the pharmacokinetics of a broad range of active principles, due to their unique combination of biocompatibility and inclusion abilities. The development of precision chemical methods for their selective functionalization, in combination with “click” multiconjugation procedures, have further leveraged the nanoscaffold nature of these oligosaccharides, creating a direct link between the glyco and the nano worlds. CDs have greatly contributed to understand and exploit the interactions between multivalent glycodisplays and carbohydrate-binding proteins (lectins) and to improve the drug-loading and functional properties of nanomaterials through host–guest strategies. The whole range of capabilities can be enabled through self-assembly, template-assisted assembly or covalent connection of CD/glycan building blocks. This review discusses the advancements made in this field during the last decade and the amazing variety of functional glyconanomaterials empowered by the versatility of the CD component.

Lately, scandals associated with the illegal addition of poisonous chemicals to food for commercial interests have been gradually disclosed to the public. Problems related to food safety do not only harm public health but also affect the stability of economic and social development. Food safety has become a common issue in society, and strengthening the related regulations have become increasingly important. Although conventional techniques are accurate and sensitive in the detection of the vast majority of illegal food additives, they rely on time-consuming, labor-intensive procedures that depend on expensive instruments. Thus, efficient and rapid identification of poisonous, illegal additives in food is a crucial task in analytical chemistry. Recently, in this context, gold nanoparticles (GNPs) have attracted considerable attention because of their optical, electronic, catalytic, and chemical properties. Their excellent properties have facilitated the widespread use of GNPs in different sensors. This review covers the two most common GNP-based sensors with colorimetric and electrochemical responses, which have proven to be effective in the detection of illegal additives. The GNP-based sensors comply with the requirement of modern analysis, such as high selectivity, sensitivity, simplicity, rapidity, and portability. Thus, they have great potential as powerful sensing tools for food safety screening. This review elucidates the utility and advances of GNP-based colorimetric and electrochemical sensors for the detection of illegal additives in the food industry and in the supervision of food quality and safety. Additionally, an outlook of the trends and future development of research on these sensors is provided.

“…Because cyclophane has multiple active sites and a unique cavity structure, it can selectively recognize guest molecules or ions [ 25 , 26 , 27 , 28 , 29 , 30 ]. It also has many properties such as optical properties, catalytic activity and drug activity [ 31 , 32 ], which gives it broad application prospects in the fields of chemical battery [ 33 , 34 ], electrochemical sensor [ 35 ], biomedical, [ 31 ] material science [ 36 ] and so on.…”

This paper reviews the most stable conformation of crystalline three-dimensional cyclophane (CP) achieved by self-assembling based on changing the type of aromatic compound or regulating the type and number of bridging groups. [3n]cyclophanes (CPs) were reported to form supramolecular compounds with bind organic, inorganic anions, or neutral molecules selectively. [3n]cyclophanes ([3n]CPs) have stronger donor capability relative to compound [2n]cyclophanes ([2n]CPs), and it is expected to be a new type of electron donor for the progress of fresh electron conductive materials. The synthesis, conformational behavior, and properties of crystalline multi-bridge rings are summarized and discussed.
