leukemia and lymphoma cells. Devil'S advocate, submit your criticism, please! Nano Letters, researchers at Massachusetts Institute of Technology (MIT) in the US show how it may be possible to do just that. Minimal information is currently available on dominant exposure routes, potential exposure levels, and material toxicity of nanomaterials. For instance, gold is the material scientists at Northwestern University use to make "nanostars simple, specialized, star-shaped nanoparticles that can deliver drugs directly to the nuclei of cancer cells. Nanomaterials are already used to lower levels of fat and sugar without altering taste, or to improve packaging to keep food fresher for longer, or to tell consumers if the food is spoiled. Overpopulation is a centuries-old problem. The idea is to use the nanofiber material not only to make operations easier for surgeons to carry out, but also so there are fewer post-op complications for patients, because it breaks down naturally over time. Research and diagnosis will be far more efficient, allowing rapid response to new diseases, including engineered diseases. Nanotechnology and Life Extension which provides more detail about some of these topics. With MM, we'll have many decades to figure out better solutions.
Prior to founding CRN, Chris Phoenix wrote a paper, ". New diseases continue to be a threat to the human race. For example, it may be desirable for the brain to receive more, or less, adrenaline than the muscles.

But, there are also concerned parties, who highlight that while the pace of research quickens, and the market for nanomaterials expands, it appears not enough is being done to discover their toxicological consequences. Health will improve and lifespans increase. No one wants to be sick, and life extension is a natural result of health extension. Also, because of their high surface area to mass ratio, nanoparticles are highly reactive, and may for instance, trigger as yet unknown chemical reactions, or by bonding with toxins, allow them to enter cells that they would otherwise have no access. But another challenge is how to quickly secure public confidence that this rapidly expanding technology is safe. Over 90 of cancer deaths are due to metastatic cancer. Integrated sampling and analysis tools will allow real-time monitoring; there will be no need for a separate "lab" to run the tests. Diagnosis and treatment may be semi-automated. The body is made of a large number of interacting systems. One of the researchers, Ned Seeman, said he envisages it will be possible to create a molecule-scale production line, where you move a molecule along till the right location is reached, and a nanobot does a bit chemisty on it, rather like "spot-welding".
