The atomic force microscope (AFM), the workhorse of scanning probe microscopes, has become even more versatile. Anneliese Raab, Wenhai Han, Dirk Badt, Sandra Smith-Gill, Stuart Lindsay, Hansgeorg Schindler, and Peter Hinterdorfer have demonstrated that the AFM, in the dynamic force mode, can use antibodies as a probe. Dynamic force microscopy uses a magnetized tip that is oscillated in an alternating magnetic field as the tip scans the surface. This provides a very gentile interaction that can be recorded as a high resolution topographic image. Raab et al., showed that more information can be obtained from the specimen.
