A team of scientists from Caltech Universityin the United States, he achieved one of the most exciting innovations in medicine: microrobots thinner than a human hair which could revolutionize the cancer treatment. Using 3D printersthese tiny robots have the ability to precisely deliver drugs directly to tumor cells, offering a much more efficient and less invasive treatment.
As small as they are efficient
with alone 30 microns thickthese robots were designed with an incredible ability to withstand extreme conditions. They can survive stomach acidan environment that would destroy many other types of technology. After completing their mission, the microrobots leave the body naturallybeing eliminated through urine. This ability to be removed without the need for external intervention is a significant advantage, as minimizes risks to the patient.
Another fascinating aspect of these robots is their ability to transform from solid to liquid and vice versa. This change of state allows microrobots adapt to different conditions inside the body, as blood flow or tumor structurewhich increases its effectiveness and versatility in treatment.
Targeted and controlled drugs
Wei Gaoprincipal investigator of the project, explained the enormous potential of this technology. “Instead of putting a drug into the body and letting it spread everywhere, we can now drive our microrobots directly to the tumor site and release the drug in a controlled and efficient way. We believe this is a very promising platform for drug delivery and precision . surgery.
Gao points out that this progress could become a platform to administer not only medications, but also more complex therapies or even perform precision surgical procedures. Furthermore, he added that, “looking to the future, we may evaluate the use of this robot as a platform to deliver different types of therapeutic payloads or agents for different conditions.”
Testing on mice: a promising first step
The research team has already carried out tests on mice, where a significant reduction in the size of bladder tumors. These results are encouraging and demonstrate the potential of the technology in real biological environments. Although it has only been tested in rodents, Gao and his team’s goal is to take this technology beyond preclinical studies: “In the long term, we hope to test it in humans.”
The future of medicine
This progress stands out not only for the technological innovation it represents, but also for its focus personalization of treatment. Cancer, as a disease, varies greatly between different people and different types of cancer. A standard treatment may not be equally effective for everyone, but microrobots offer the possibility of creating personalized, health-based therapies specific needs of each patient. This represents a step forward towards more precise, less invasive and much more targeted medicine.
