combination spheres for targeting of liver tumors

Protein spheres, containing both anti-cancer drugs and magnetic particles, can be introduced by a catheter and released to surrounding the liver tumor. These “combination spheres” are designed to be deliberately large so that they will obstruct blood flow bringing nutrients to the tumor.

In addition, under an alternating magnetic field, the magnetic particles will heat up to specifically kill the tumor cells. The anti-cancer medication will be released locally, concentrating in the area of the tumor and avoiding toxicity to the rest of the body.
