Localization of single avidin-biotin interactions using simultaneous topography and molecular recognition imaging
Sprache des Titels:
Two-for-one: The authors discuss a powerful new tool that, in a single dynamic force microscopy scan, maps the topography of a surface and simultaneously recognizes specific target sites (see figure). Topography and recognition images correlated nicely at a lateral resolution of a few nanometers. This clever technique has great potential for a broad range of applications involving the detection of particular binding sites in native biological systems.
