The greatest problem with traditional cancer treatments is lack of specificity. Treatments such as radiation therapy and chemotherapy kill healthy cells along with tumor cells, causing negative side effects in patients (1). Scientists believe that nanotechnology-based treatments can solve the issue of specificity. Nanoparticles used to treat cancer are approximately...
