your question doesnt make sense… but nanotechnology is on the nanoscale, manipulating materials at this level is a hope for the future of science to create better, smaller and more efficient technology. Im sure i read in multiple websites that the household computer with all its specs can be made to be the size of a bacteria. But nanotechnology is a broad feild,

if your looking at advantages check out..

and also disadvantages i can only think of the ‘grey goo’ thoery, which is totally stupid, but go for your life,

en.wikipedia.org/wiki/Grey_goo

but if you wanna understand the basics of it at the atomic level check these out..

www.nanotech-now.com/basics.htm

www.crnano.org/basics.htm

bear in mind the date of the websites as future ambitions may be slightly unrealistic by todays standard, or nanotechnology may have developed since then. best of luck.

How does Nanotechnology or Drugs in General find specific Target Areas?

Question by laptoprabbit: How does Nanotechnology or Drugs in General find specific Target Areas?
I’m wondering, for example, you take medicine for a painful kidney (this is just for instance). How does the medicine know exactly where to go? Let’s take this a step further and pretend we are dealing with nanotechnology. How would the nanos (basically, really small particles) know where to deposit the drugs to the kidney? Is there some sort of chemical reaction going on, and if so, how and what? Thanks, and please tell me the source.

Answer by Mapleaf11
There are certain biological formations that can help deliver drugs or genetic materials to cells–liposomes, for instance, have medicine or genetic material encapsulated in them, and they can either be absorbed into a cell or join with the cell membrane to release their cargo. Also, dendrimers are tree-like protein polymer structures that form “pockets” within them, and the medicine or genetic material is deposited into the pockets and delivered directly to the tumor or organ that needs them. These treatments are specifically targeted at the necessary cells, similar to radiation or chemotherapy in cancer treatment. They would be injected or delivered directly to the site. I would say that a source to start with would be the book we used as our beginning textbook in my nano program. It includes many other sources for continuing research into the subject.
