“…The obtained nanoparticles were tested as fluorescent probes for dual-metal ions. 105 The affinity of the γ-CD rim for the silver surface was confirmed by the presence of the -OH stretching vibration displaced at 3443 cm -1 in the FT-IR spectrum. The SPR band at about 410 nm, and the TEM images, indicated the existence of spherical nanoparticles.…”

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.

In recent studies, researchers have been dedicated to the synthesis of silver nanoparticles (AgNPs) that can be adjusted in size, owing to their unique physical and chemical properties. In this study, AgNPs with well‐defined and stable characteristics are successfully functionalized with Gallic acid (GA) within a polymer matrix consisting of polyvinyl alcohol/β‐cyclodextrin polymeric biofilms (BFs) using a casting approach. To evaluate the particle size, functional groups, and crystallinity of the AgNPs, various techniques including UV, FT‐IR, TEM, and XRD are employed. The prepared BF films (BFs) are comprehensively analyzed for mechanical strength, color ratio, swelling ratio, surface morphology, elemental ratio, thermal behavior, and water wettability using stress–strain analysis, spectrophotometer color lab, SEM, EDAX, TGA, and contact angle techniques. Furthermore, the antimicrobial properties of the BFs are also investigated, along with their antioxidant activity assessed through the DPPH radical assay. The multifunctional BFs exhibited promising potential as antimicrobial agents for food preservation.
