Metal-Phenolic NetworksMPNScience Figure 1 Polyphenol Assembly 

Polyphenols, these plant-derived natural products, were traditionally referred to as vegetable tannins, due to their original use in the industrial process of tanning to convert animal hide into leather. The possibility to exploring the unique physicochemical and biological properties of polyphenols can serve as an important source of inspiration in the search for new and improved materials. A library of functional metal-phenolic network (MPN) nanostructured films and capsules was reported which is based on the coordination between a phenolic ligand and a range of metal ions. Furthermore, the polyphenol-based particle functionalization was discoved by Dr. Guo to facilitate an interfacial molecular interaction-induced self-assembly process. This allowed for the generation of a highly versatile and effective methodology to prepare a large variety of superstructures assembled from a wide range of building blocks. This method displayed significant versatilities of sizes, shapes, microstructures, and compositions as building blocks. The generic nature of this method led to a large family of modularly assembled superstructures including core-satellite, hollow, hierarchically organized supraparticles, and inorganic-biological hybrids. In functional aspects, the polyphenol-based materials were tailored for biosythesis, seawater uranium extraction, advanced drug delivery, positron emission tomography (PET), magnetic resonance imaging (MRI), catalysis, electromagnetic (EM) applications, etc.
