Bionano Lab, University of Guelph

Bionanolab at the School of Engineering, University of Guelph is focused on studying the nanoscale aspects of biological systems through instrumentation and nano-scale imaging tools. Our group fosters interdisciplinary approach to research in studies covering diverse topics of food, agricultural, and biomedical systems.

Our Laboratory

Bionano lab is located at the Thornbrough Building, School of Engineering of the University of Guelph. The lab is a multidisciplinary facility with a wide range of tools and instruments providing collaborative workspaces for nanoscale engineering research. The lab is configured for optical imaging, atomic force microscopy imaging, and microfluidics.

Our Projects

Our research interests include design, development and optimization of devices, tools, methodologies, and processes using nanoscale science and engineering for biological and agricultural systems. Research topics in the 'bio-nano' theme is a symbiosis of ideas from diverse fields, and calls for synergistic collaboration between engineers, chemists, biologists, physicists and other experts. In this broader context, we pursue research topics across multiple disciplines.


The primary goal is to introduce students to the role of nanoscience and nanotechnology advances and research as applied to biological systems, and prepare a diverse set of students for their future studies and career. Fostering critical thinking, facilitating the acquisition of life-long learning skills and preparing students to function effectively are the expected outcomes of Professor Suresh's teaching.
