Recent Advances of Metal–Polyphenol Coordination Polymers for Biomedical Applications

Abstract

Nanomedicine has provided cutting-edge technologies and innovative methods for modern biomedical research, offering unprecedented opportunities to tackle crucial biomedical issues. Nanomaterials with unique structures and properties can integrate multiple functions to achieve more precise diagnosis and treatment, making up for the shortcomings of traditional treatment methods. Among them, metal–polyphenol coordination polymers (MPCPs), composed of metal ions and phenolic ligands, are considered as ideal nanoplatforms for disease diagnosis and treatment. Recently, MPCPs have been extensively investigated in the field of biomedicine due to their facile synthesis, adjustable structures, and excellent biocompatibility, as well as pH-responsiveness. In this review, the classification of various MPCPs and their fabrication strategies are firstly summarized. Then, their significant achievements in the biomedical field such as biosensing, drug delivery, bioimaging, tumor therapy, and antibacterial applications are highlighted. Finally, the main limitations and outlooks regarding MPCPs are discussed.

Chromaticity of Gromwell, Cape Jasmine Dyeing, and Effects of Zinc Oxide/Polyphenol Treatment with Copper Mordanting for UV Protection

“…Ultraviolet (UV) radiation exposure can cause skin aging and inflammation due to the damage to collagen, hyaluronic acid, and protein [1][2][3][4]. Some functional fabrics can protect the skin exposed to UV rays by absorbing, transmitting, and reflecting UV light.…”

“…Since the global ozone crisis, ultraviolet (UV) radiation exposure has posed the threat of skin aging, inflammation, and severe damage to collagen, hyaluronic acid, and protein [1][2][3][4]. In a highly developed chemical industry, skin protection by covering functional fabrics results from the control of UV exposure by absorbing, transmitting, and reflecting UV light.…”

“…The improvement in UV protection could be attributed to the fact that a large amount of ZnO and polyphenols from plant extracts were adsorbed onto inherently hollow cotton fibers, leading to UV absorption. The metal-polyphenolic coordination materials can result in synergistic effects on antioxidants and antiaging against the broad ranges of UV light, with tannins acting as organic UV absorbers and ZnO acting as inorganic UV blockers [3].…”
