Chemistry is all around us
It impacts everything we can see, touch, smell and taste. The programs of the Department will prepare you to understand,investigate and apply the principles of chemistry to a wide variety of careers from the study of the environment, to solving criminal cases, to working in a chemically related business, to using chemistry to understand biological systems and processes, to preparing for a career as a research chemist.
Our faculty provide teaching and research expertise in all major areas of Chemistry
The Department offers weekly seminars by faculty from departments throughout the United States and beyond describing the latest advances in their fields.

" Paper-Based Microfluidic Biosensors for Molecular Diagnostics "
Paper, as a ubiquitous material in everyday life, has been reinvented into low-cost yet effective microfluidic platforms for bioanalysis. In this seminar, I will present our recent research on developing new types of paper-based biosensing platforms for molecular diagnosis of life-threatening diseases. The research has been focused on designing new paper devices, investigating advanced detection mechanisms, integrating functional biosensing nanomaterials, and optimizing analytical performance. These efforts have enabled unique features of these diagnostic platforms, including low material and manufacturing costs, superior analytical performance, simplified device operation, and excellent user-friendliness. The paper-based platforms I will discuss include: (i) a shape memory polymer (SMP) actuated microfluidic platform for autonomous enzyme-linked immunosorbent assays (ELISA); (ii) an electrochemical biosensor array for multiplexed diagnosis of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) co-infection; and (iii) a zinc oxide nanowire (ZnO NW) biosensor for ultrasensitive detection of glucose and HIV protein biomarkers. Our ongoing efforts on clinical sample testing of these platforms will also be briefly introduced.
Xinyu Liu is an assistant professor in the Department of Mechanical Engineering at McGill University, and also holds positions of the Canada Research Chair in Microfluidics and BioMEMS and the Chwang-Seto Faculty Scholar. He received his M.Eng. and B.Eng. degrees in mechanical engineering from Harbin Institute of Technology, China, in 2002 and 2004, respectively; and his Ph.D. degree in mechanical engineering from the University of Toronto, Canada, in 2009. Prior to joining McGill in 2011, he was a NSERC Postdoctoral Research Fellow in the Department of Chemistry and Chemical Biology at Harvard University. At McGill, he directs the Biomedical Microsystems Laboratory, with research focused on microfluidic and lab-on-a-chip technologies for applications such as molecular diagnostics, environmental analysis, and cell/organism manipulation. Dr. Liu received the Star in Global Health Award from Grand Challenge Canada, Douglas R. Colton Medal for Research Excellence from CMC Microsystems, and seven best paper awards at major engineering and biomedical conferences.He is a co-inventor of 12 US/PCT patents (issued or pending) on microsystem technologies.
