Researchers from Binghamton University, along with collaborators from North Carolina State University, Harvard Medical School, and Duke University, have made a groundbreaking discovery in particle manipulation within liquid droplets using ultrasound waves. This innovative technique has the potential to revolutionize various fields, particularly in biomedical testing and drug development.
Assistant Professor Yuyang Gu, a key figure in this research, envisions a future where their findings pave the way for cutting-edge technologies that can significantly impact the medical and pharmaceutical industries. This discovery stems from a deep understanding of the physics behind manipulating particles suspended in liquid using ultrasound waves.
The team’s research, recently published in the journal Science Advances, sheds light on the intricate process of inducing spin in liquid droplets by generating ultrasound waves on a piezoelectric substrate. This phenomenon causes the fluid within the droplet to circulate in a helical pattern, ultimately concentrating particles at the droplet’s center.
Gu and his colleague, Assistant Professor Chuyi Chen, have been at the forefront of this research, delving into the complexities of the system to unlock its full potential. By fine-tuning parameters such as surface tension, droplet size, and ultrasound wave characteristics, they can control the movement and concentration of particles within the droplet more precisely.
Aside from its immediate applications in biomedical testing and drug development, this novel technique also presents an opportunity to explore fundamental questions in physics, drawing parallels to natural systems and microscopic phenomena. The vortex created within the spinning droplet mirrors patterns observed in nature, offering insights into quantum physics and electron behavior.
Looking ahead, Gu and his collaborators are eager to expand the scope of their research. They aim to explore the effects of different parameters on the system by experimenting with droplets of varying sizes and configurations. By scaling up the technology to create arrays of spinning droplets, they envision a future where multiple droplets can work in tandem, enhancing the efficiency and practicality of the technique.
As this cutting-edge research continues to evolve, the team remains committed to pushing the boundaries of what is possible with ultrasound wave manipulation in liquid droplets. Their work not only opens up new avenues for technological advancements but also contributes to a deeper understanding of the underlying physics governing these intricate systems.
