The quest for earlier and more effective cancer diagnoses has lead researchers to explore various avenues, with liquid biopsies becoming a particularly compelling area of study. While circulating tumor DNA (ctDNA) has gained meaningful traction, circulating tumor cells (CTCs) – the actual living cancer cells traveling in the bloodstream – offer a richer understanding of a patient’s disease.
the challenge with CTCs has always been their rarity. Unlike ctDNA, which can be amplified for analysis, the number of CTCs found in a typical blood draw is ofen limited. But now, scientists at the K. N. Toosi University of Technology in Tehran, Iran, have developed a groundbreaking technology that promises to change the game.
“We combined machine learning algorithms with data-driven modeling and computational data to fine-tune a system for optimal recovery rates and cell separation rates,” explains Naser Naserifar, co-researcher on the project. “Our system achieves 100% recovery at optimal conditions,with significant reductions in energy consumption through precise control of acoustic pressures and flow rates.”
This innovative method, published in the journal Physics of Fluids, utilizes standing surface acoustic waves (SSAWs) to separate CTCs from the overwhelming majority of red blood cells within a microfluidic channel. The researchers strategically designed the channel’s geometry and applied dualized pressure acoustic fields, creating a targeted environment that effectively isolates CTCs.
“We have produced an advanced, lab-on-chip platform that enables real-time, energy-efficient, and highly accurate cell separation,” states Afshin Kouhkord, another co-author of the study. “The technology promises to improve CTC separation efficiency and open new possibilities for earlier and more effective cancer diagnosis.”
The implications of this technology extend far beyond improved cancer diagnosis. The potential for portable,lab-on-chip diagnostic devices opens the door for real-time cancer detection and monitoring. Moreover, the system’s ability to generate detailed cell interaction data provides invaluable insights into tumor cell behavior and migration – key factors in understanding how cancer spreads.
“The integration of Multiphysics Finite Element Method and multivariate surrogate modeling… generate datasets that predict the performance of the proposed acoustic micro-electro-mechanical system in explaining the cell migration phenomena,” the researchers wrote. “This innovative approach in laboratory-on-chip technology paves the way for personalized medicine, real-time molecular analysis, and point-of-care diagnostics.”
While further research is needed to refine the system for large-scale applications and diverse cancer types, this breakthrough represents a significant leap forward in the field of cancer diagnostics. By leveraging machine learning and advanced acoustics,researchers are paving the way for personalized medicine and more effective cancer treatment strategies.

Harnessing Sound Waves for Cancer detection: An Exclusive Interview
In a groundbreaking growth in the fight against cancer, scientists have devised a new method for detecting circulating tumor cells (CTCs) using sound waves. Dr. Afshin Kouhkord, a co-author of the groundbreaking study published in the journal *Physics of Fluids*, spoke exclusively with Archyde to shed light on this revolutionary technology.
Archyde: Dr. Kouhkord, your recent research highlights a new approach to detecting CTCs using acoustic waves. Could you explain the fundamental concept behind this innovation?
Dr. Kouhkord: Certainly. Traditionally, identifying CTCs from blood samples has been challenging due to thier scarcity. Our method utilizes standing surface acoustic waves (SSAWs) to selectively isolate CTCs from other blood cells. Essentially, we manipulate sound waves within a microfluidic channel designed with specific geometry, creating pressure gradients that efficiently separate CTCs.
Archyde: that’s interesting.What are the advantages of using acoustic waves over existing CTC detection techniques?
Dr.Kouhkord: Traditional techniques often involve complicated procedures or expensive reagents. Our method boasts several advantages, including its efficiency, affordability, and the ability to analyze cells in real-time. By precisely controlling acoustic pressures and flow rates, we achieve 100% recovery of CTCs in optimal conditions while minimizing energy consumption. Furthermore, we can capture valuable data about the interaction between CTCs and sound waves, offering insights into their behavior.
Archyde: Could you elaborate on the role of machine learning in your research?
Dr. Kouhkord: Machine learning algorithms played a crucial role in optimizing the acoustic microfluidic chip’s design. Through computational modeling, we fine-tuned various parameters to ensure precise separation rates. We used datasets generated from the Multiphysics Finite Element Method and multivariate surrogate modeling to predict the performance of our acoustic system.
Archyde: The implications of your research are immense. Where do you see this technology impacting cancer diagnostics and treatment in the future?
Dr. Kouhkord: Imagine portable,lab-on-a-chip devices enabling immediate cancer detection at the point of care.Our technology can pave the way for real-time monitoring of cancer progression, personalized treatment strategies, and deeper understanding of tumor behavior. imagine earlier diagnosis leading to better patient outcomes!
Archyde: Your work truly opens doors to personalized and proactive healthcare. One crucial question for the future: How soon do you anticipate widespread implementation of this technology?
Dr. Kouhkord: While further research is needed to refine the technology and adapt it for diverse cancer types, the groundwork is laid. Clinical trials are essential for validating the effectiveness in diverse patient populations. Based on current progress, I anticipate seeing wider clinical applications within 5-10 years, transforming the landscape of cancer care.
The potential for ultrasound-based CTC separation technology to revolutionize cancer diagnostics and pave the way for personalized medicine is truly remarkable. We eagerly anticipate witnessing the positive impact of Dr. Kouhkord’s groundbreaking work.
