Research Areas


Prof. Guo initiated a series of pioneering research on polyphenol-based multifunctional materials and interfacial self-assembly, encompassing more than 60 peer-reviewed publications in a range of high-impact journals, including Science, Nature Nanotech., Energy Environ. Sci., Angewandte Chem. Int. Ed., Adv. Mater., Chem. Sci., etc (more information on the Publication page). Prof. Guo explored the use of polyphenols on particle self-assembly for the generation of superstructures and inorganic-biological hybrids. These parts of works have been published in Science and Nature Nanotech. as highlighted articles. In 2014, he reported the library of metal-phenolic networks (MPNs) materials, which represent the establishment of novel multifunctional materials based on polyphenols. This part of the work has been published in Angew. Chem. Int. Ed. as the front cover and draw broad attention in the material filed. Prof. Guo's works have been reported by more than 20 international scientific media, including F1000 (Exceptional), EurekAlert!, Harvard Gazette, ChemViews Magazine,, IDI-Online, etc.


Our mission: use bio-building blocks to create materials 

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 were reported which is based on the coordination between a phenolic ligand and a range of metal ions. Furthermore, the polyphenol-based particle functionalization was discovered by Prof. 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 biosynthesis, seawater uranium extraction, advanced drug delivery, positron emission tomography (PET), magnetic resonance imaging (MRI), catalysis, electromagnetic (EM) applications, etc.
