In the daily introductions today, I found out that the whole concept of nanotechnology is not new at all. It has dated back all the way to Leonardo Da Vinci’s time, in which we would perform dissections on dead human bodies, which was not really done at his time.
The formation of movies regarding nanotechnology started in 1966, in the film, Fantastic Journey. After the daily introduction, a guest speaker named Leonard Rome lectured on nano medicine. He mentioned that electronic noise would become future sensors of abnormal metabolites in breath. Quantum dots are clusters of semi-conductor materials, which admit light at a very specific angle by their size. Their movements are visible in live cells.
In his lecture, he also brought up that tumors have large gaps in them, like leaky blood vessels. Basically, nano medicine will use engineering molecular systems and molecular knowledge of the human body to maintain and improve health as a whole. A short break was then given before Hilary Godwin, specializing in nano toxicology, started her speech. Nothing is safe. An overdose of almost anything can kill you, even if all you did was drink an intense amount of water. Nano silver use in regulation is controversial, because it has an unknown, possibly bad effect to the environment. On the good side, it helps ward and kill off bacteria.
A good example was a video she had shown to us talking about nano silver socks, and how they were effective and did their job.
