Micro-Nano Systems

Our devices, tools, and solutions are getting smaller.

Micro and nano systems research focuses on the fabrication and integration of nanometer scale structures and devices.

Micro, nano, and molecular-scale systems are at the core of emerging technologies and solutions in health, digital and manufacturing sectors, such as in lab on chip diagnostics, micro-machining, additive manufacturing, solar energy capture, advanced nano-scale materials science and microlectricomechanical systems in razor thin devices.

With groups working on cutting edge nano-materials, microelectronics, microfluidics, and the fascinating effects of changing material properties at the atomic scale, McMaster Engineering is a world leader in the field, with some of the best researchers and institutes.
