“…Biswick et al [27] also intercalate an active agent, caffeic acid, into ZLH nanocomposite as sunscreen material. Caffeic acid was chosen due to its high potential as a material for cosmetic applications and its low stability against UV and oxygen irradiation [117][118][119]. The finding of slow release for caffeic acid-zinc basic salt (CA-ZBS) shows a fast release in the first 20 min, which is due to small amounts of anions adsorbed on the surface of the inorganic matrix and to anions intercalated close to the edges of the crystals, followed by slow release with time.…”

Zinc Layered hydroxide (ZLH) is a layered material easily synthesized with a structure identical to brucite-like material. Due to the exchangeable anions in the interlayer compensating for the positive charge of a brucite-type layer, ZLH provides a wide application in many fields. This review focuses on the properties and method of synthesis of ZLH by giving an overview of intercalated guest anion in the interlayer of ZLH. The further discussion involved the application of intercalated guest anion in zinc layered hydroxide layer and its properties as a sensitizer, controlled release biomedical, and agriculture to provide the scientific community for research and development by giving current findings. This brief review also presents the success of anion intercalation for controlled release along with the kinetic model involved, which increases the bioavailability and effectiveness of the nanocomposite on its target. It shows the development of research on ZLH nanocomposites toward the sustainability of human life and the environment. This study implies that it is a source of knowledge for researchers about zinc-layered hydroxide materials involving synthesis methods and their application to produce more beneficial nanomaterials.

“…Nevertheless, the main drawback of these materials is their rigidity and low deformation capability (reported elongation at break was around 2%), limiting the surface adaptability during application. In the same line Arruda Fernandez et al summarizes the advantages to combine the properties of bacterian cellulose with phenolic compounds to prevent the UV-induced skin damage [27]. Moreover, particularly employing cholinium gallate in combination with silk fibroin Gomez et al reported the preparation of sponges with antioxidant and anti-inflammatory features to be in tissue engineering strategies due to the benefits of the phenolic compound.…”

Polyphenol Iongel Patches with Antimicrobial, Antioxidant and Anti-Inflammatory Properties

There is an actual need for developing materials for wound healing applications with anti-inflammatory, antioxidant, or antibacterial properties in order to improve the healing performance. In this work, we report the preparation and characterization of soft and bioactive iongel materials for patches, based on polymeric poly(vinyl alcohol) (PVA) and four ionic liquids containing the cholinium cation and different phenolic acid anions, namely cholinium salicylate ([Ch][Sal]), cholinium gallate ([Ch][Ga]), cholinium vanillate ([Ch][Van]), and cholinium caffeate ([Ch][Caff]). Within the iongels, the phenolic motif in the ionic liquids plays a dual role, acting as a PVA crosslinker and a bioactive compound. The obtained iongels are flexible, elastic, ionic conducting, and thermoreversible materials. Moreover, the iongels demonstrated high biocompatibility, non-hemolytic activity, and non-agglutination in mice blood, which are key-sought material specifications in wound healing applications. All the iongels have shown antibacterial properties, being PVA-[Ch][Sal], the one with higher inhibition halo for Escherichia Coli. The iongels also revealed high values of antioxidant activity due to the presence of the polyphenol, with the PVA-[Ch][Van] iongel having the highest activity. Finally, the iongels show a decrease in NO production in LPS-stimulated macrophages, with the PVA-[Ch][Sal] iongel displaying the best anti-inflammatory activity (>63% at 200 µg/mL).
