Abstract: The present invention provides a scanning probe microscope cantilever comprising a support portion, a lever portion extended from the support portion, and a needle projecting out of a first surface of the cantilever in the vicinity of a free end of the lever portion. From a second surface of the cantilever opposite the first surface, a bore extends through the needle to an aperture formed at a tip of the needle. To the tip of the needle, a substantially globular particle is attached. A method of scanning a sample surface comprises creating relative cantilever motion substantially toward the sample such that the particle experiences a contact force with the sample, illuminating a top surface of the cantilever with laser light such that a portion of the laser light passes through the hollow needle and is emitted from the aperture onto the particle, and detecting scattered light from the sample.
