The treatments used to treat cancer patients eliminate the tumors, but they frequently have unfavorable side effects on the patients as well. However, a new study examined how gold nanoparticles can dispense cancer drugs with not only great accuracy but might also significantly reduce the chance of negative side-effects that are typically observed with cancer drug treatments. The work was published in ACS Applied Materials & Interfaces.An illustration of the study’s gold nanoparticle drug delivery technology.
