More on anticancer drug delivery using nanoparticles

I just came across an article in http://www.medicalnewstoday.com which goes over the use of  use of gold nanoparticles carrying drug molecules to target and treat cancer cells, something that was already presented in this post last February. This confirms that scientist keep foreseeing nanotechnology as new treatment against cancer, which might also replace radiation, chemotherapy, etc... in a near future.

In the study presented, the researchers used a single-stranded DNA aptamer called AS1411 which does two jobs. The first is to bind with the "shuttle" protein nucleolin, which is over-expressed in cancer cells and present inside the cell and on the cell surface. The second job is, once it is released from the nanostar, is to act as the drug itself. The results were quite more than satisfactory, as scientist observed death and decline in cancer cell population, exactly the intended objective.
