Dr. Duan received his B.S. and M.S. degrees from Fudan University in Chemistry and Macromolecular Sciences. He completed his PhD in Physical Chemistry at Max Planck Institute of Colloids and Interfaces and Postdam University in 2005. After that, he moved to the Department of Biomedical Engineering at Emory University and Georgia Institute of Technology for his postdoctoral training. Before joining the School of Chemical and Biomedical Engineering as a Nanyang Assistant Professor in 2009, he was an Assistant Professor (research track) in Biomedical Engineering at Emory University. He was promoted to Associate Professor with tenure in 2015 and to Professor in 2020.
His current research focuses on understanding surface/interface properties of microscale and nanoscale colloidal particles to achieve tailored optical, electronic, magnetic, catalytic, and structural properties, and exploring their biomedical and environmental applications. He is particularly interested in new chemistry towards nanostructures with structurally integrated inorganic nanocrystals and polymers and new approaches towards well-defined multifunctional assemblies of nanoscale building blocks. The key research topics in his lab include: Plasmonics and Surface-Enhanced Optical Properties; Interfacial Assembly of Colloidal Particles; In Vitro Diagnostics; Detection and Treatment of Antimicrobial Resistance; Controlled Delivery of Biologics.

US 2019/0366733 A1: A Process For Isotropic Structural Colour Printing And An Apparatus For Detecting A Target Substance In The Gaseous Phase (2021)
Abstract: According to the present disclosure, an isotropic structural colour printing process is provided. The process comprising (a) providing an ink composition comprising ink particles (such as polymeric particles (e.g. polystyrene), metal-organic frameworks (MOFs) (e.g. ZIF-8)) in a liquid reagent; and (b) depositing the ink composition onto a surface of a substrate (e.g. anodic aluminium oxide membrane, photo papers). Due to capillary action and/or absorption of the liquid reagent, the ink particles form an amorphous arrangement of structures that lead to isotropic structural colour. In the preferred embodiment, the ink particles may further be coated with a catechol group (such as polydopamine). An apparatus for detecting a target substance in the gaseous phase, wherein the apparatus comprises a nanostructure capable of exhibiting a change in isotropic structural colour when one or more molecules of the target substance are entrapped as an indication that the target substance is present, is also provided.

US 2017/0304796 A1: Method For Preparing A Magnetic Chain Structure (2021)
Abstract: A method for preparing a magnetic chain structure is provided. The method comprises providing a plurality of magnetic particles; dispersing the plurality of magnetic particles in a solution comprising a dopamine-based material to form a reaction mixture; applying a magnetic field across the reaction mixture to align the magnetic particles in the reaction mixture; and polymerizing the dopamine-based material on the aligned magnetic particles to obtain the magnetic chain structure. A magnetic chain structure prepared by the method is also provided.
