“…[83][84][85] In particular, traces of norfloxacin in milk were identified through the inclusion of the drug into the β-CD cavity in β-CD/AgNPs previously obtained using β-CD as a reducing agent. 86 The formation of the norfloxacin/β-CD inclusion complex was demonstrated by theoretical and experimental analyses, 87 and its proximity to the nanoparticle surface induced relevant changes in the spectral properties of the β-CD/AgNPs. In the presence of norfloxacin, the surface plasmon resonance band of the β-CD/AgNPs solution shifts from 410 to 405 nm, and a decrease in the absorbance intensity can be observed.…”

The association between cyclodextrins (CDs) and silver nanoparticles (AgNPs) has been successfully exploited in a large number of applications. Generally, CDs act as stabilizers, however, their reactivity as reducing agents can be directly involved in the synthesis of AgNPs. Herein, the most recent results regarding AgNPs prepared by chemical reduction from native α-, β-and γ-cyclodextrins are reported. The behavior of CDs in host-guest inclusion complexes onto the metal surface, and the effects on the AgNPs properties have also been examined. Unlike β-CD/AgNPs and γ-CD/AgNPs, additional reducing agents were required for the investigated α-CD/AgNPs.

The culture filtrate of Hypocrea lixii GGRK4 played a vital role as a reducing and stabilizing agent in the mycosynthesis of silver nanoparticles (AgNPs) using silver nitrate (AgNO3). The extracellular extract derived from fungi emerged as a noteworthy option for synthesizing AgNPs due to its potential composition of metabolites, including enzymes and other bioactive substances. Hence, the presence of a dark brown color serves as a key indicator for the biosynthesis of AgNPs through the reduction of Ag (I) ions to Ag by the fungal culture filtrate. To facilitate the synthesis of AgNPs, a combination of hybrid technologies, specifically the “one factor at a time” approach and statistical tools such as response surface methodology, was used using a face-centered central composite design (FCCCD). Utilizing a modified CX medium with pH of 5.02 supported the fungi synthesizing AgNPs at a temperature of 30°C. The multi-efficient AgNPs were characterized through various techniques, including UV–visible spectrophotometry, zeta size and potential analysis using a zeta size analyzer, transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and fluorescence spectroscopy. The biosynthesized AgNPs have significant associated functional groups, revealed by FTIR analysis. TEM histogram analysis showed that these multi-efficient AgNPs have a size of 17.34 nm. Similarly, they have emission and excitation spectra of 450 nm and 390 nm, respectively, revealed by fluorescence spectrum analysis. Compared to the standard, the biosynthesized AgNPs have significant antibacterial and free radical scavenging properties and dye degradation capability. Additionally, the half-maximal inhibitory concentration (IC50) value was found statistically significant based on t-test analysis. Finally, the biosynthesized AgNPs could be used in potential applications encompassing ecofriendly degradation, antimicrobial activity, and therapeutic applications, such as free radical scavenging properties.

“…Norfloxacin (NFX) in milk increases human resistance to the drugs and threatens public health. Qiu et al proposed a sensitive method for NFX determination based on SERS using β-CD functionalized AgNPs (β-CD-AgNPs) as substrates [ 101 ]. Due to the unique steric size and hydrophilicity of β-CD on the surface of AgNPs, NFX can be captured selectively by weak interactions such as hydrogen bonding interaction and electrostatic interaction.…”

Food safety issues are a major threat to public health and have attracted much attention. Therefore, exploring accurate, efficient, sensitive, and economical detection methods is necessary to ensure consumers’ health. In this regard, cyclodextrins (CDs) are promising candidates because they are nontoxic and noncaloric. The main body of CDs is a ring structure with hydrophobic cavity and hydrophilic exterior wall. Due to the above characteristics, CDs can encapsulate small guest molecules into their cavities, enhance their stability, avoid agglomeration and oxidation, and, at the same time, interact through hydrogen bonding and electrostatic interactions. Additionally, they can selectively capture the target molecules to be detected and improve the sensitivity of food detection. This review highlights recent advances in CD inclusion technology in food safety analysis, covering various applications from small molecule and heavy metal sensing to amino acid and microbial sensing. Finally, challenges and prospects for CDs and their derivatives are presented. The current review can provide a reference and guidance for current research on CDs in the food industry and may inspire breakthroughs in this field.
