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.
