Metal-phenolic networks (MPNs), which comprise supramolecular amorphous networks formed by interlinking polyphenols with metal ions, garner escalating interest within the realm of nanomedicine. Presently, a comprehensive synthesis of the cumulative research advancements and utilizations of MPNs in nanomedicine remains absent. Thus, this review endeavors to firstly delineate the characteristic polyphenols, metal ions, and their intricate interaction modalities within MPNs. Subsequently, it elucidates the merits and demerits of diverse synthesis methodologies employed for MPNs, alongside exploring their potential functional attributes. Furthermore, it consolidates the diverse applications of MPNs across various nanomedical domains encompassing tumor therapy, antimicrobial interventions, medical imaging, among others. Moreover, a meticulous exposition of the journey of MPNs from their ingress into the human body to eventual excretion is provided. Lastly, the persistent challenges and promising avenues pertaining to MPNs are delineated. Hence, this review offering a comprehensive exposition on the current advancements of MPNs in nanomedicine, consequently offering indirect insights into their potential clinical implementation.

Probiotic powder using a single protective method during freeze-drying is insufficient vitality because it lacks adequate protection. Here we developed a protection strategy through biointerfacial phenolic self-assembly to enhance the protection of excipients for probiotics to address existing challenges during freeze-drying. This strategy could strengthen the connections of excipients and phenolic protective layers containing hydroxyl groups with water molecules, improving the hydration layer's preservation and shielding bacteria from damage.

Injectable hydrogels hold promise for drug delivery and biomedical applications but often lack multifunctional properties such as antibacterial activity, self-adhesion, and controlled drug release. This study developed a multifunctional gelatin-based hydrogel using modified cassava starch waste (CSW) and a metal-phenolic complex from spent coffee grounds (ex-SCG). The CSW was used to prepare aldehyde starch (DAS), while ferric ions formed metal-ligand bonds with phenolic compounds extracted from ex-SCG.

Cancer immunotherapy is the most promising method for tumor therapy, while ferroptosis could activate the immunogenicity of cancer and strengthen the cellular immune response. However, limited by the complex tumor microenvironment, the abundant glutathione (GSH) and low reactive oxygen species (ROS) seriously weaken ferroptosis and the immune response. Herein, the authors report photothermal metal-phenolic networks (MPNs) supplied with buthionine sulfoximine (BSO) by reducing levels of GSH and then trapping the tumor cells in the ferroptosis and immunotherapy cascade loop to eliminate colorectal cancer (CRC).

Hypoxia, a prevalent characteristic of solid tumors, substantially impairs the efficacy of cancer treatments. However, there are no feasible clinical approaches for treating hypoxic tumors. Here, we develop metal-phenolic networks (CuGI) utilizing the natural glycolysis inhibitor (epigallocatechin gallate) and the essential metal element in the human body (copper ions), specifically targeting and annihilating hypoxic cancer cells.

Metal-phenolic networks (MPNs) integrated with functionalized cellulose nanofibers present a promising platform for stabilizing oxidation-sensitive compounds. Here, a novel antioxidant pickering emulsion system utilizing MPN-decorated carboxyl-functionalized pulp cellulose nanofibers (MPN-PCNF) is demonstrated. The system exhibits exceptional interfacial stability through synergistic effects of MPN coating and alkyl functionalization, validated by DLVO theoretical modeling and rheological characterization.
