Nanotechnology is being developed to more effectively treat cancer. Researchers are engineering nanoparticles that can locate and map tumors, carry drug payloads to destroy cancer cells, and potentially be used for imaging and treating tumors in humans. One hybrid nanoparticle under development contains magnetic, fluorescent, and drug components to home in on cancer cells, be seen on MRI, and deliver anti-cancer drugs. The potential of these nanoparticles for cancer treatment is high but researchers are cautious about timelines. Aging is also an area of research, with the goal of developing techniques to remove harmful free radicals that accumulate and cause cellular damage over time. Some believe that with further research and funding, the technology may exist to live indefinitely by preventing biological aging processes.
