Small robots direct drugs to specific areas of the body; understand

The configuration and composition of these microrobots enable the biocompatibility of hydrogels

Robot small can assist in the distribution of medicines in specific areas of body. They are microspherical structures produced by a hydrogel known as poly(ethylene glycol) diacrylate.

The configuration and composition of these microrobots enable the biocompatibility of hydrogels. The manufacturing process also allows the ball to deliver the medicine to a specific location in the body. In other words: targeted therapies.

Gao, one of the study’s authors, explains that: “Instead of putting a medicine into the body and letting it spread everywhere, we can now drive our microrobots directly to the tumor site and release the medicine in a controlled and efficient way.”

The team was able to produce microstructures around 30 microns in diameter. To be clear, it is equivalent to the diameter of a human hair. The microrobots, in their final version, incorporate magnetic nanoparticles and therapeutic drugs into the external structure of the spheres.

See how it works:

Furthermore, the institute’s note informs that magnetic nanoparticles allow researchers to guide robots towards a specific point, using an external magnetic field. “When the robots reach their goal, they stay in that location and the medicine passively spreads outward,” the team explains.

The final step in the evolution was to test microrobots as a tool for administering medicines to mice suffering from bladder tumors. The scientists found that four doses given over 21 days were more effective at shrinking tumors than a non-robot-administered therapy.

This is a tactic that has received a lot of attention in recent years: small robots that deliver drugs directly to the affected organ.
