“…Tea polyphenols are hydrophilic, biocompatible, and biodegradable, and can function as both reducing and capping agents for metal NPs. Tea polyphenols have been used as reducing agents for the fabrication of Ag [15,20,21] or Au NPs [22][23][24] using Ag + or AuCl 4 − as raw materials, respectively. For example, Moulton et al prepared Ag NPs using tea extracts at room temperature.…”

Polyphenols, the phenolic hydroxyl group-containing organic molecules, are widely found in natural plants and have shown beneficial effects on human health. Recently, polyphenol-containing nanoparticles have attracted extensive research attention due to their antioxidation property, anticancer activity, and universal adherent affinity, and thus have shown great promise in the preparation, stabilization, and modification of multifunctional nanoassemblies for bioimaging, therapeutic delivery, and other biomedical applications. Additionally, the metal−polyphenol networks, formed by the coordination interactions between polyphenols and metal ions, have been used to prepare an important class of polyphenol-containing nanoparticles for surface modification, bioimaging, drug delivery, and disease treatments. By focusing on the interactions between polyphenols and different materials (e.g., metal ions, inorganic materials, polymers, proteins, and nucleic acids), a comprehensive review on the synthesis and properties of the polyphenol-containing nanoparticles is provided. Moreover, the remarkable versatility of polyphenol-containing nanoparticles in different biomedical applications, including biodetection, multimodal bioimaging, protein and gene delivery, bone repair, antibiosis, and cancer theranostics is also demonstrated. Finally, the challenges faced by future research regarding the polyphenol-containing nanoparticles are discussed.

“…TA was used to stabilize collagen chains via hydrogen bonding and hydrophobic interactions and protect the collagen structures from enzymatic degradation. − TA can also cross-link DNA via interactions with phosphate groups or PEG via hydrogen bonds, forming a mucoadhesive and biodegradable hydrogel for biomedical applications. In addition, TA was used as a polyanion component in Layer-by-Layer (LbL) particle or film formulations − or to modify the surface of inorganic NPs such as gold, − cobalt ferrite, and silica . However, TA has not been fully investigated as a reactive layer for surface modification of polymeric NPs.…”

Polymeric nanoparticles (NPs) are decorated with various types of molecules to control their functions and interactions with specific cells. We previously used polydopamine (pD) to prime-coat poly(lactic-co-glycolic acid) (PLGA) NPs and conjugated functional ligands onto the NPs via the pD coating. In this study, we report tannic acid (TA) as an alternative prime coating that is functionally comparable to pD but does not have drawbacks of pD such as optical properties and interference of ligand characterization. TA forms a stable and optically inert coating on PLGA NPs, which can accommodate albumin, chitosan, and folate-terminated polyethylene glycol to control the cell-NP interactions. Moreover, TA coating allows for surface loading of polycyclic planar aromatic compounds. TA is a promising reactive intermediate for surface functionalization of polymeric NPs.

“…Likewise, tannic acid stabilized/coated gold nanoparticles are prepared by mixing a chloroauric acid solution with tannic acid. Herein, tannic acid functions as a stabilizer but also allows the reduction of Au 3+ to form Au nanoparticles [ 65 , 67 ]. Furthermore, it is shown that tannin–gold hybrid materials cannot solely be produced using hydrolyzable tannins but also in a similar manner in a one-pot approach by using the condensed bayberry tannin [ 68 ].…”

Tannin-Based Hybrid Materials and Their Applications: A Review

et al. 2020

View full text Add to dashboard Cite

Tannins are eco-friendly, bio-sourced, natural, and highly reactive polyphenols. In the past decades, the understanding of their versatile properties has grown substantially alongside a continuously broadening of the tannins’ application scope. In particular, recently, tannins have been increasingly investigated for their interaction with other species in order to obtain tannin-based hybrid systems that feature advanced and/or novel properties. Furthermore, in virtue of the tannins’ chemistry and their high reactivity, they either physicochemically or physically interact with a wide variety of different compounds, including metals and ceramics, as well as a number of organic species. Such hybrid or hybrid-like systems allow the preparation of various advanced nanomaterials, featuring improved performances compared to the current ones. Consequently, these diverse-shaped materials have potential use in wastewater treatment or catalysis, as well as in some novel fields such as UV-shielding, functional food packaging, and biomedicine. Since these kinds of tannin-based hybrids represent an emerging field, thus far no comprehensive overview concerning their potential as functional chemical building blocks is available. Hence, this review aims to provide a structured summary of the current state of research regarding tannin-based hybrids, detailed findings on the chemical mechanisms as well as their fields of application.
