Nanorobot with hidden weapon kills cancer cells
Researchers at Karolinska Institutet have developed nanorobots that kill cancer cells in mice. The robot’s weapon is hidden in a nanostructure and is exposed only in the tumour microenvironment, sparing healthy cells. The study is published in the journal Nature Nanotechnology.

The researchers also plan to investigate whether it is possible to make the nanorobot more targeted by placing proteins or peptides on its surface that specifically bind to certain types of cancer. ”A DNA Robotic Switch with Regulated Autonomous Display of Cytotoxic Ligand Nanopatterns”, Yang Wang, Igor Baars, Ieva Berzina, Iris Rocamonde-Lago, Boxuan Shen, Yunshi Yang, Marco Lolaico, Janine Waldvogel, Ioanna Smyrlaki, Keying Zhu, Robert A Harris, Björn Högberg, Nature Nanotechnology, online 1 July 2024, doi: 10.1038/s41565-024-01676-4.
