Cancer develops when abnormal cells in the body begin to grow and spread very fast. These bad cancer cells are often not that different from healthy cells, which makes cancer treatment difficult. Most cancer treatments kill some of the healthy cells along with the bad cells, making patients sick. What if you could design a treatment that would only target the cancer cells and leave the healthy cells untouched? Nanotechnology may one day make this possible.
While nanotechnology is not yet used to treat diseases, many new technologies are being tested. Scientists have many ideas about how nanoparticles might be used to combat diseases.
