Micro-Robot Created by Israeli Researchers to Navigate and Capture Cells
Israeli researchers from Tel Aviv University have developed a micro-robot the size of a single biological cell that uses both electricity and magnetic fields to navigate and capture cells. This groundbreaking development opens up a range of potential applications in various fields. Inspired by naturally occurring “swimmers” like bacteria and sperm, the researchers created a micro-robot with the ability to move autonomously or under the control of an operator.
Advantages of Using Magnetic Fields and Electricity
The researchers chose to use a magnetic field to propel the micro-robot, also known as a micro-motor, due to its numerous advantages. Unlike fuel-powered propulsion methods or direct contact with body tissues, the magnetic field method is fuel-free, accurate in steering, and can function in a wide range of temperatures and solution conductivities. While electrically powered micro-motors offer benefits like selective cargo loading, transport, and release, as well as the ability to deform cells, they can be less effective in environments with high electrical conductivity. By combining the two propulsion systems, the researchers found a way to overcome these limitations.
Demonstration of Capabilities
Once assembled, the hybrid propulsion system proved its capabilities in capturing various types of cells. The micro-robot successfully captured a single red blood cell, cancer cells, and a bacterium. This demonstration showcased the micro-robot’s ability to distinguish between healthy cells, cells damaged by drugs, dying cells undergoing apoptosis, and more. The captured cells can then be moved to an external instrument for further analysis.
Additional Advantages and Potential Applications
The hybrid micro-robot also has the capability to capture non-labeled cells by sensing their status, a feat not accomplished previously. The researchers believe that this innovative technology has the potential to revolutionize several areas, including medical diagnosis at the single cell level, delivering drugs or genes into cells, genetic editing, targeted drug delivery within the body, environmental cleanup, drug development, and even creating a “laboratory on a particle.”
Future Prospects
Although the testing was conducted outside the human body, the researchers are optimistic about testing the hybrid micro-robot inside living organisms (in vivo) soon. With its vast potential, this technology could have far-reaching implications in various fields. The study detailing the micro-robot’s development and capabilities was published in the journal Advanced Science.
