Recently, I read an article from Nature about a new system of techniques that enabled folding of DNA to create virtually any type of shapes or patterns. Currently they are only capable of bending DNAs into two dimensional shapes. They are working on techniques to generate 3 dimensional shapes.
These shapes much much smaller and cheaper than what has been done by other techniques in nano-structure designing because most of the structure is generated by self-assembling. Mass production of nano structures are now possible because, you dont have to move everything into place unit by unit any more. Just cut the strands and “drop them in the test tube” and tada! you have lots of nano-structures floating around.
I am not an expert of DNAs or nanostructures, but this one caught my imagination. The articles on the web describes the future of this technique in creating nanobreadboards and other devices.
I don’t know the future, but imagine the possibilities of designing nano-mouse-trap or a trap-door-cage that can trap a virus or a prion into a lot of steric hinderance, thus prevent it from interacting with anything. The trap can be designed for just one virus or a class of viruses. That will be an end to fears of a flu pandemic. Drug research and development will be lot cheaper and quicker because mutated viruses will also get traped in the same nano-structure and all one has to do to trap a new virus is modify the generic-trapdoor-framework. People will virtually disease free, living longer.
Even deeper into the future, we may have structures capable of storing information, storing probed data in some format using some nano-mechanical-dexterity or traped molecules (eg: cynocobalamin means 1, folic acid means 0) or qbits stored in embedded quantum dots.
We will send these structures near every neuron to measure its state and encode them into these quantum dots they carry. Using some advanced nuclear magnetic resonance these states will be measured and transfered to a super complex turing machine that can emulate your brain. That will be good alterego till you pull the plug.
Big Words. Pure Nonsense.
