Investigators at Northwestern University have found that packing small interfering RNA (siRNA) molecules onto the surface of a gold nanoparticle can protect siRNAs from degradation and increase their ability to regulate genes involved in cancer. As a result of this discovery, cancer researchers have at their disposal a relatively straightforward method of delivering these potent gene-regulating agents into targeted cells.
