Mapping local interaction forces by AFM
Mapping local interaction forces by AFM Introduction The AFM combines a very sharp sensor, which can be positioned in all three dimensions with an accuracy of order Ångstrøm, with an ultrasensitive force [...] When combining force measurements and positioning the tip laterally on the sample interaction forces can be mapped locally (6), which has been applied to measure local electrostatic interactions (7) or local [...] occurred! Code: 20230721182329d12521f3 Colloidal Forces In AFM all forces known from colloidal physics can be present. Always present are van der Waals forces, which are in most cases attractive and on the
