  • Peakforce photothermal-based detection of IR nanoabsorption
    Patent number: 10520426
    Abstract: An apparatus and method of performing photothermal chemical nanoidentification of a sample includes positioning a tip of a probe at a region of interest of the sample, with the tip-sample separation being less than about 10 nm. Then, IR electromagnetic energy having a selected frequency, ?, is directed towards the tip. Using PFT mode AFM operation, absorption of the energy at the region of interest is identified. Calorimetry may also be performed with the photothermal PFT system.
    Type: Grant
    Filed: August 1, 2017
    Date of Patent: December 31, 2019
    Assignee: Bruker Nano, Inc.
    Inventors: Gregory O. Andreev, Chanmin Su
