Seeing is believing - Nanoscale Imaging of Biological, Chemical, and Physical Processes
Biologists, chemists and physicists lack tools to observe the ubiquitous processes in liquids with nanoscale resolution. Our work aims at developing novel tools based on micro and nanofabricated devices for high resolution imaging with light and electron microscopes to provide new insights into biological, physical and chemical processes.
One part of our work is to develop systems for in-situ TEM studies of nanoscale processes. We work on gas phase reactions on microfabricated heaters and novel chips systems to image processes in liquids. Another part of our work is exploring interactions between cells and nanostructures. We are developing focused ion beam milling combined with scanning electron microscopy to provide 3D images of cells based on standard and cryogenic fixation methods.
Student projects
It is always possible to do a student project within these research areas. We have posted several suggestions for student projects in the DTU database

Ongoing Research Projects:
FTP Sapere Aude project Liquid EM on Imaging nanoscale processes in liquids with electron microscopes (1.1.12-31.12.16).
Environmental electron microscopy methods have been developed for mainly studying gas phase reactions, but live imaging of processes in the liquid phase is lagging behind. We are developing microfluidic system with thin membrane windows that are transparent to the electron beam in SEM and TEM. Combining these windows with the diverse functionality of microfluidic chip systems makes it possible to obtain electron microscopic images with nanoscale resolution in liquids to study numerous processes under controlled conditions, such as biological, chemical and electrochemical processes.
