Using a biodegradable polymer produced by a slime mold, a team of investigators from Cedars-Sinai Medical Center has created a multifunctional nanoparticle that attacks a key pathway involved in breast cancer in two different ways. Tests using animals with human breast tumors showed that the new nanoparticle produced a 90% reduction in tumor growth.
