Professor, Chemistry

Research interests: functional DNA, biosensors, nanozymes, and biointerface chemistry


Over the past six years, Professor Juewen Liu has published over 200 research papers on DNA/lipid-based sensors and functional materials with a total citation number close to two thousand.

Liu is a leader in the field of bionanotechnology. His lab employs DNA, liposomes, hydrogels, and various inorganic nanoparticles as building blocks to construct functional nanomaterials for analytical and biomedical applications. He is also interested in the biotechnology of combinatorial DNA aptamer selection.

Liu joined the Department of Chemistry at the University of Waterloo in July 2009. Prior to his current appointment at University of Waterloo, he worked for two years as a postdoctoral fellow at the Center for Micro-Engineered Materials in the University of New Mexico, and the Advanced Materials Laboratory in Sandia National Labs, where he developed a novel drug delivery vehicle based on mesoporous silica nanoparticle supported phospholipid bilayers. He is currently interested in selection of functional DNA molecules for catalysis and molecular recognition, enzyme mimics using nanomaterials (nanozymes), adsorption of DNA and lipids on various nanoscale surfaces, and biosensor development.
