Tomorrow – Researchers at the University of Toronto have successfully developed micro-robots to study the human cell, which could lead to new hopes and a new cancer treatment technique, or even better information on resistance to chemotherapy.
A team of researchers from the University of Toronto in Canada has created a group of micromagnetic clamps that can implant a small robot inside the human cell with extreme precision.
The robot takes the form of a tiny pill and can be used to study the properties of cancer cells, which could pave the way for many possibilities for diagnosis and treatment of the disease.
Sue Sun and her team at the University of Toronto's Faculty of Engineering have been producing nanoparticles for nearly 20 years, which can perform various measurements of the cell, offering scientific benefits in areas such as artificial insemination, medicine personal, etc.
"Until now, the robot has explored the external structure of the cell and is now trying to probe the inside of the cell," said Su-Sun, a researcher at Suo Sun.
System
The team has succeeded in designing a robotic system capable of analyzing the cellular structures beneath the lenses of the electron microscope, which requires freezing, drying and cutting into small pieces.
Other research teams use techniques such as laser and sound waves to study cells. The technique involved the use of six magnetic poles placed at different locations around the microscope slide, said researcher Xian Wang, involved in the study.
The diameter of the robotic bean is 700 nm, about 100 times the diameter of the human hair, which allows it to be implanted in the cancer cell.
Once the cell is implanted in the cell, Wang is driven by an algorithm that controls the electrical current of the magnetic poles surrounding the microscope. The magnetic field is formed by three-dimensional shapes that move the grain in the desired direction in the cell.
"Imagine if you could use a whole swarm of robotic granules to kill a cancerous tumor by blocking the blood vessels that feed it, or destroy it directly by mechanical amputation," he said.
He added that this technique would allow the treatment of tumor tumors resistant to chemotherapy and radiation.
