Atomic force microscopy detects differences in the surface brush of normal and cancerous cells


Using an atomic force microscope (AFM), researchers at Clarkson University in New York have found that normal cells have “brushes” of one length on their surface while cancerous cells have two brush lengths that have very different densities to the brushes on normal cells. Cancer and normal cells may therefore interact very differently with nanoparticles ; according Igor Sokolov, one of the authors of the study, “this phenomenon could be used for cancer detection and potential treatment through drug delivery“.
