Bionanotechnology is a branch of nanotechnology which uses biological starting materials, utilises biological design or fabrication principles or is applied in medicine or biotechnology. 

Bionanotechnology has become an exciting field of research and an area of technology development, especially since the length scale nanotechnology can access more and more coincides with the length scale of basic biological structures and fundamental biological components.

The Bionanotechnology group at NTNU was started in 2006 as part of the NTNU NanoLab initiative, an effort to bring several branches of nanotechnology together in one lab.

The research team is part of Biophysics and Medical Technology. We work on the interactions between biological systems and nanostructured surfaces the characterisation of selected biopolymer-based nanostructures and their application in materials or structure fabrication.
