“…On account of their facile synthesis, high chemical stability, and easy surface functionalization, the AuNPs have become important building blocks for novel hybrid nanomaterials. ,, In parallel, macrocyclic hosts (cyclodextrins, calixarenes, cucurbiturils, etc.) possess unique and sizetunable cavity structures and exhibit special properties. − On the basis of host–guest interactions, they have been well-applied for self-assembly, drug/gene delivery, separation, sensing, etc. ,, Recently, researchers are pushing ahead to synthesize and assemble the hybrid nanomaterials of metal NPs and macrocycles (cyclodextrins, , calixarenes, − and cucurbiturils). Integration of AuNPs and macrocyclic hosts significantly combines and enhances the merits and characteristics of the two component parts, including the optical, electronic, and catalytic performances of AuNPs and supramolecular recognition capability of the macrocyclic hosts, expanding their potential technological applications such as sensors, drug delivery, and catalysis. , …”

A novel, green, one-pot synthesis of gold nanoparticles (AuNPs) was obtained by the redox reaction between AuCl 4 − and hydroxylatopillar[5]arene (HP5) in aqueous solution with the aid of OH − at room temperature without the need of a traditional harsh reducing agent such as NaBH 4 , N 2 H 4 , etc. Monodisperse AuNPs with a uniform diameter of ∼5.0 nm are fabricated via the proposed one-step colloidal synthesis route by using HP5 as both reducing agent and stabilizer, while AuNPs cannot be effectively protected by noncyclic monomers of HP5. The FTIR, 13 C NMR, and XPS studies demonstrated that the hydroxy groups in HP5 reduce Au 3+ into Au 0 , which leads to nucleation, growth, and formation of AuNPs, and the hydroxy groups themselves are oxidized to carboxyl groups. It is surprising that the HP5 functionalized AuNPs can self-assemble and form multiple well-defined architectures, including vesicles, like nanotubes, and one-/two-dimensional (1D/2D) nanostructures without the need of a guest mediator. The selfassembly mechanism was also studied. Moreover, the prepared HP5@AuNPs could be employed as not only scaffolds but energy acceptors for turn-on fluorescence sensing based on a competitive host−guest interaction. In addition, the AuNPs exhibited very excellent catalytic activity for the reduction of 4-nitrophenol (4-NP). We believe that the versatile HP5@AuNPs could be potentially used in the field of self-assembly, sensing, and catalysis.

“…So AgNPs are often designed for colorimetric sensing systems. Moreover, the determination of analytes with AgNPs can be carried out with the naked eye without the need for sophisticated equipment and complex procedures [45]. However, the disadvantage of this AgNPs-based colorimetric sensor is poor sensitivity due to its susceptibility to surface oxidation, so surface functionalization plays an important role in enhancing the stability and analytical application of AgNPs [36].…”

Colorimetric sensors-based silver nanoparticles (AgNPs) are very interesting to be studied and developed because of the simplicity and ease in the principle of detection. It does not require sophisticated and affordable tools but still has high sensitivity. The coefficient extinction of AgNPs is relatively higher than AuNPs of the same size, making the sensitivity of AgNPs higher than AuNPs. The principle of detection is based on the aggregation of nanoparticles with analytes that causes shifting in Localized Surface Plasmon Resonance (LSPR) to a larger wavelength, commonly called a bathochromic shift or redshift. It is a favorite phenomenon because it is more easily observed with naked eyes. This sensor shows a good analytic performance with high sensitivity due to strong LSPR and good strategies that selectively bring interaction between analytes and AgNPs. AgNPs are characterized using UV-Visible (Ultra Violet-Visible), TEM (Transmission Electron Microscope), FTIR (Fourier Transform Infrared), and DLS (Dynamic Light Scattering), and many analytes have been detected with this sensor successfully. This article discusses several important parameters in increasing the sensitivity of AgNPs colorimetric sensors. Finally, it can be used as guidelines in the development of methods in the future.

“…Presence of a large flexible hydrophobic cavity in sulfonatocalix [6]arene CA-12 opens the possibility of complexation with fluorescent ligands. Such double functionality opens the possibility of making three-component systems in which a fluorescent ligand acts as a bridge between cyclophane-modified silver nanoparticles [43]. A highly sensitive H 2 PO 4…”

Silver nanoparticles (AgNPs) are an attractive alternative to plasmonic gold nanoparticles. The relative cheapness and redox stability determine the growing interest of researchers in obtaining selective plasmonic and electrochemical (bio)sensors based on silver nanoparticles. The controlled synthesis of metal nanoparticles of a defined morphology is a nontrivial task, important for such fields as biochemistry, catalysis, biosensors and microelectronics. Cyclophanes are well known for their great receptor properties and are of particular interest in the creation of metal nanoparticles due to a variety of cyclophane 3D structures and unique redox abilities. Silver ion-based supramolecular assemblies are attractive due to the possibility of reduction by “soft” reducing agents as well as being accessible precursors for silver nanoparticles of predefined morphology, which are promising for implementation in plasmonic sensors. For this purpose, the chemistry of cyclophanes offers a whole arsenal of approaches: exocyclic ion coordination, association, stabilization of the growth centers of metal nanoparticles, as well as in reduction of silver ions. Thus, this review presents the recent advances in the synthesis and stabilization of Ag (0) nanoparticles based on self-assembly of associates with Ag (I) ions with the participation of bulk platforms of cyclophanes (resorcin[4]arenes, (thia)calix[n]arenes, pillar[n]arenes).
