The development of nanotechnology has great relevance to the future of healthy longevity; at its simplest, aging is a matter of atoms and molecules being out of place. As our ability to control the building blocks of matter improves, so too will medicine improve in leaps and bounds. Here is an interesting discussion from Nanowerk - experts in the field looking ahead to what is to come: " One of the beautiful things about biology is that biology functions at many different length scales, and all of those length scales are working together to make the being functional. So if you think about down to the molecular scale, to DNA and coding and genetic information, to protein that the genetic information codes, to tissues that it builds up to functional levels - you know, human beings walking around - it's pretty fascinating to think about how all that works together. But it is all basically encoded in these molecules within cells. ... I think the impact of nanoscience in medicine is going to grow dramatically over the next 10 to 20 years, especially in the field of regenerative medicine. Another thing that I am hopeful about is that we will be able to hijack the brilliant mechanisms of biology to construct for us functional non-biological nanosystems. ... one area that's absolutely ripe for incredible advances is the life sciences and medicine, where aggregations of individual nanodevices to create nanosystems will allow us to embrace, rather than run away from, the complexity of biological systems and will give us the tools, I believe, to understand and engineer biological circuitry, which as the root of systems biology and ultimately, I think, will give a technological foundation for personalized medicine. ... I believe that the broad umbrella of nanoscience is rapidly dissolving the traditional barriers between [disciplines], and maybe wiring them a bit together with the idea that now people are thinking about atoms and materials as arbitrary forms, not in the historical sense. Physicists are now using biological systems, and biologists are exploiting solid state devices and microfluidic devices within a myriad of research efforts. People are thinking much more broadly than in the past [and] I think it's the discoveries in science that are driving this direction. When I look at the students who are entering the university system, they're highly motivated by the idea of breaking down the normal barriers and focusing on the new scientific opportunities that emerge."
