Patent Number: 
Section: abstract

Manipulators for handling micron-scale samples, methods for making probes for the manipulators, and methods for using the manipulators are provided. An exemplary manipulator includes a probe, a probe holder, and a mechanical positioner. The probe includes an electrically conductive surface, a proximal end and a distal end where the distal end has a truncated conical shape with a generally flat face, and a bore extending from the proximal end to the face. The probe holder engages the proximal end and includes an inlet in fluid communication with the bore and with a source of sub-ambient pressure. An exemplary microscopy inspection method includes forming a free-standing membrane, positioning the probe of the manipulator proximate to the membrane, drawing the membrane to the face by drawing a vacuum through the bore, placing the membrane on a sample support, and inspecting the membrane with a microscope.
