Nanoparticles in form of tiny spheres and rods of gold are useful tools in modern medicine. They have been incorporated into miniature drug-delivery systems to control blood clotting, and they are also the main components of cancer diagnostic devices and as nanomedicine (gold nanorods) for treating malignant tumors. The gold spheres are sticky, so gold nanoparticles can be engineered to attract specific biomolecules so that they could boost up amount of protein produced during in-vitro translation. Gold nanosphere-DNA complex is designed to bind to a specific m-RNA molecule, which will be translated into a specific protein. Gold nanosphere-DNA complex can help in determining protein function by observing cell behavior; when the protein has been removed or can also stop the production of harmful proteins. Gold nanoparticles are cellular nanomedicine showing promising results in cancer therapy.
