Soft and Hard materials, drug delivery and controlled release

Associate Professor Chun-Xia Zhao's research focuses on the development of biomolecule-templating technology and microfluidic platform technology for making novel bio-inspired functional materials for applications in drug delivery and controlled release. Her research discoveries have led to four patented technologies. The biomolecule-templating technology she co-invented opens a new strategy for fabricating next-generation core-shell materials in a sustainable and biocompatible way. Her breakthrough microfluidic mass transfer control technology offers a facile but unique approach for turning single emulsions into complex emulsions using only a simple T-junction microfluidic device. Based on these two technologies, her group has developed facile and scalable methods for producing libraries of multifunctional materials for drug delivery and controlled release, and has been developing tissue chips to evaluate these systems with the ultimate goal of accelerating their clinical translation. Current areas of focus include multifunctional nanomaterials for targeted drug delivery, bioinspired silica capsules for controlled release, and in vivo mimicking tissue chips for screening and evaluating nanomaterials.

Associate Professor Chun-Xia Zhao is an Australian Research Council (ARC) Future Fellow and Group leader at Australian Institute for Bioengineering and Nanotechnology at The University of Queensland, Australia. She leads a research team with a focus on bio-inspired engineering and microfluidics. She has been focusing on innovative research as evidenced by her four patents. Associate Professor Zhao’s research has attracted more than $2.7 M in research funding since 2011, including four Australian Research Council projects as the lead investigator, two national prestigious fellowship (Australian Postdoctoral Fellowship and ARC Future Fellowship), and seven UQ grants. Associate Professor Zhao has been recognised for scientific excellence with a 2016 UQ Foundation Research Excellence Award. She has built extensive collaborations with scientists at top universities such as Harvard University, Cornell University, etc. She was invited to visit Harvard University as a Fellow of the School of Engineering and Applied Science. She also serves as the Editor-in-Chief, Editorial Board member for several journals. 

Industry Engagement

Associate Professor Zhao has been active in patent applications to transfer her research into practical applications, as evidenced by her four patents.
