  • Publication number: 20240230520
    Abstract: A tip-enhanced spectroscopy may include a substrate on which liquid containing an analyte is to be positioned, a tip extending from a fixed end to a free end adjacent to a location for the analyte, and a vibration source configured to harmonically vibrate the tip based on a preset natural frequency. The preset natural frequency may be a natural frequency of a tuning fork.

  • Publication number: 20120102601
    Abstract: Disclosed herein is a scanning probe microscope having an improved structure to precisely control a distance between a scanning probe and a surface of a sample. The scanning probe microscope includes a sample stage having a support structure on which a sample to be measured is placed and generating vibration, and a scanning probe not attached to the sample stage but independently constituted and scanning a surface of the sample placed on the sample stage and vibrated by the sample stage.

  • Patent number: 8087093
    Abstract: Provided is a mechanically-coupled tuning fork-scanning probe vibrating system, the system including: a tuning fork vibrating due to an AC voltage applied thereto; a scanning probe attached to a side of the tuning fork and vibrating due to the tuning fork; and a contact member contacting a side surface of the scanning probe and adjusting a position of a contact point at which the contact member contacts with the scanning probe, to vary a natural frequency of a combination body in which the tuning fork and the scanning probe are combined with each other.
