Purpose of the Study:

• To investigate the effects of low-frequency ultrasound on erythrocyte aggregation.
• To develop and validate a model for ultrasound-induced erythrocyte behavior.
• To explore the therapeutic potential of a patented low-frequency ultrasound transducer.

Main Methods:

• Development of a mathematical model for erythrocyte aggregation under acoustic waves.
• Utilizing a patented low-frequency ultrasound transducer generating traveling acoustic waves.
• Statistical analysis using the t-test to confirm ultrasound's effect on erythrocyte aggregation.

Main Results:

• Demonstrated rapid movement of erythrocytes towards acoustic wave nodes.
• Quantified erythrocyte dissociation rates under shear forces.
• Confirmed statistically significant effect of low-frequency ultrasound intensity on erythrocyte aggregation.

Conclusions:

• Low-frequency ultrasound, via traveling acoustic waves, can disrupt erythrocyte aggregates.
• The patented technique is presumed safe for in vivo therapeutic applications.
• Potential applications include improved microcirculation, plaque disruption, tumor treatment, drug encapsulation, and diabetic foot ulcer therapy.
