Patent number: RE43117Abstract: The invention is an apparatus and method including hardware and software, which allows collecting and analyzing data to obtain information about mechanical properties of soft materials in a much faster way. The apparatus can be used as a stand-alone deice or an add-on to the existing AFM device. The apparatus allows collecting dynamical measurements using a set of multiple frequencies of interest at once, in one measurement instead of sequential, one frequency in a time; measurements.Type: GrantFiled: May 9, 2011Date of Patent: January 17, 2012Assignee: Clarkson UniversityInventor: Igor Sokolov
