A quick check-up shows there's cause for healthy optimism, though. Let's look at some people making progress.
There's a company encapsulating nanoparticles of the active ingredient in a proven cancer-fighting drug in microspheres, helping eliminate sever allergic reactions many patients have to the drug. Another lab is working on temperature-activated coatings for cancer drugs. The coating shields the drug at normal body temperature. When the compound reaches the treatment site, a slight rise in body temperature breaks down the coating, releasing the active drug. Another study is working with magnetism as the "release agent." They link drugs to nano-particles of iron oxide, then use a magnetic force that causes the iron to warm slightly, releasing the treatment.
There's even a university group working on making nano-diamonds a cancer-fighter's best friend. Clusters of diamonds carry chemotherapy drugs, but shield the drug from interaction with normal cells which they can damage.
