Abstract: A method of measuring dissociation of the biomolecular bonds in one or multiple sample wells using super-resolution force spectroscopy (SURFS). SURFS utilizes precise ultrasound radiation to exert an acoustic radiation force on the biomolecular bonds labeled with magnetic particles. The force-induced dissociation of the protein bonds labeled with magnetic particles may be measured as a reduced magnetic signal by a magnetic sensor. The force resolution allows for differentiating biomolecular bonds with an extremely high level of precision. The biomolecular bonds include protein-protein, protein-nucleic acid, nucleic acid-nucleic acid, small molecule-protein, and small molecule-nucleic acid interactions.

Abstract: There is provided an apodizing wedge structure for a LIPUS treatment head. The LIPUS treatment head includes a low-volume fraction piezoelectric composite disc. The apodizing wedge structure includes an annular body for contacting a surface of the piezoelectric disc, the annular body including an inner perimeter having an inner thickness and an outer perimeter having an outer thickness. The annular body includes an inclined surface forming a continuous slope extending from the inner perimeter to the outer perimeter, the inner thickness being smaller than the outer thickness. The apodizing wedge is configured to change an apparent thickness of the piezoelectric disc with respect to resonant properties of the piezoelectric disc when the apodizing wedge structure is in acoustic communication with the piezoelectric disc, thereby allowing the LIPUS treatment head to generate a uniform near field. LIPUS treatment heads and ultrasonic transducers including such an apodizing wedge structure are also provided.

Abstract: An ultrasonic stepping motor device for generating ultra-fine single droplet includes a valve housing, a valve core, and a spring. The valve core and the spring are installed inside the valve housing, and the valve core abuts against a liquid inlet of the valve housing under an elastic force of the spring. The valve housing is connected with a injector through a catheter, and the catheter is driven for linear operation by the inverse piezoelectric effect of piezoelectric ceramics through an ultrasonic linear motor. A right end of the catheter is equipped with a rubber piston, and the rubber piston is arranged in a cavity of the injector and matched with the injector. Since the piezoelectric vibrator driven catheter can produce nano feed length, and the volume of droplets overflowed each time can reach micron level, which can meet the requirements of producing micro droplets.

Abstract: Provided is a piezoelectric module capable of attempting further miniaturization. In the piezoelectric module, a resonance point is excluded from a frequency band of a transmitted signal to avoid shortening of a signal transmission distance, thereby attempting improvement in stability of communication. In addition, since a resonance space is not provided, further miniaturization may be easily attempted.
