Read moreBy combining a nanoparticle made of a polymer produced by a slime mold with a cancer targeting agent and two therapeutic antisense nucleic acids, an international team of researchers has created a new type of nanoparticle that accumulates in brain tumors when injected into mice. Laboratory tests also demonstrated that this multifunctional nanoparticle stops malignant glial cells from producing two proteins that these cells need to grow.
