Left panel: (A) The scheme of experimental setup (a) and force distribution on a glass particle treated with the laser beam generated by OT (b–d)32; (B) Transmitted light microscopy image presenting AFM cantilever before (a) and after (b) glass particle attachment.. Right panel: (C) The image of experimental setup with the scheme showing the course of the OT laser beam and the optical path of the microscope. I—bright field illumination, II—sample, II.1—AFM cantilever with colloidal probe II.2—OT laser beam, III—trapping objective, IV—OT laser source, V—OT main shutter, VI—camera.
