Our lab (hogberglab.net) at the Karolinska Institute (ki.se) in Stockholm is working in the field of bioengineering. We use DNA nanotechnology to develop applications and methods that employ this technology for biological and medical research. As an example, we have recently published a method where DNA origami is used to probe receptor activation based on nanoscale separation between ligand in a breast cancer cell-line (Nature Methods 11, p. 841 (2014)).
