The research, which was conducted on mice, demonstrates how these tiny nanomachines are propelled by urea present in urine and precisely target the tumor, attacking it with a radioisotope carried on their surface.
Bladder cancer has one of the highest incidence rates in the world and ranks as the fourth most common tumor in men. Despite its relatively low mortality rate, nearly half of bladder tumors resurface within 5 years, requiring ongoing patient monitoring. Frequent hospital visits and the need for repeat treatments contribute to making this type of cancer one of the most expensive to cure.
While current treatments involving direct drug administration into the bladder show good survival rates, their therapeutic efficacy remains low. A promising alternative involves the use of nanoparticles capable of delivering therapeutic agents directly to the tumor. In particular, nanorobots—nanoparticles endowed with the ability to self-propel within the body—are noteworthy.
