A novel class of engineered nanoparticles that can aim, image and destroy tumor cells could be a potential way to deal with cancer. This system contains gold nanoparticles with branching polymers called dendrimers that sprout off the nanoparticle's surface. The particles could be used to launch a multiprong attack against tumors. The dendrimer arms can carry a number of different molecules, including molecules that target cancer cells, fluorescent imaging agents, and drugs that slow down or kill the cells. The aim is to bind this material to, knock out the oncogene without harming anything else. The researchers are yet experimenting on animals to know the results.

Finally the researcher say gold nanoparticle enveloped in treelike polymer branches could act as a multipurpose tool for fighting cancer.
