摘要
A general high-throughput screening (HTS) process using an atomic force microscope (AFM) to detect and measure molecular recognition events. The AFM is used to measure changes in molecular complex height, friction, shape, elasticity or any other relevant parameters that report a molecular recognition event. In addition, the force involved in molecular recognition and bonding is directly measured using the technique of force spectroscopy. In one embodiment, a flow chamber is used to introduce molecules and assay their effect on a molecular interaction occurring between molecules on the AFM probe and a surface. In some cases the surface may be an introduced microparticle. In a second embodiment, the sample is a solid phase array of molecules that is interrogated by a functionalized AFM probe, and the effects of introduced agents at each molecular address in the array is measured by force spectroscopy.
