They manage to reduce the size of a bladder tumor by 90% using nanorobots: “They float in our body” – Catalonia

The study reached reduce bladder tumors by 90% using nanorobots. The study was carried out on mice and was led by the Institute of Bioengineering of Catalonia (IBEC) and CIC biomaGUNE in collaboration with the Institute of Biomedical Research of Barcelona and the Autonomous University of Barcelona.

This work opens the door to new treatments for this type of cancer that reduce hospitalization time, meaning lower costs and greater patient comfort.

Current treatments that involve injecting drugs directly into the bladder have demonstrated good survival rates but low therapeutic efficacy.

“Nanorobots are nanoparticles that can move independently inside the body.” Samuel Sanchez from IBEC explains: “Imagine nanoparticles that are self-propelled, can move, float, and then float in the urea that is in our urine and even in the bladder, and they are so effective that in one injection we are able to reduce more than 90% of the tumor size.”

How tall is the nanorobot?

Sanchez explains that “those of us who Their diameter is 300 or 400 nanometers, which is about 1000 times smaller than the diameter of a human hair.more or less to have an idea or double the size of the virus”

Now a study published in the journal Nature Nanotechnology shows how the research team reduced the prevalence of bladder tumors in mice by 90% by administering a single dose of urea-powered nanorobots.

How many medications can they carry?

This is exactly the key change we made a couple of years ago. A robot can’t carry much, but if you launch swarms of nanobots, millions of nanobots, they can do something.” – concludes the IBES researcher.

Researchers are now studying whether tumors come back after treatment.
