I'm going to write here a little summary of the book "Bionanotechnology: Lessons from Nature" writen by David S. Goodsell. This is an assignment for my major in Bioinformatics in the University of New Orleans. I hope you will enjoy it ;) Please, report any error to correct it. I'm learning and it will be very useful for me :D 

Nanotechnology is the ability to construct any kind of machine with a known and predefined number of atoms, instead of the traditional machines which have an arbitrary number of them. To do this, one idea is to construct an "assembler", a machine capable of making another machines. This machine was supposed to be the great new advance, with it the "2-weeks revolotion" would be possible. This is, if you have a machine able to construct another machines in a very short time you can do whatever you want. But nowadays this is far from our possibilities. That is why the bionanotechnology is important.Biology already has implemented an extraordinary number of nanomachines and has tested them during millions of years within an evolution process. This tests are much more optimized than any test we can make. In each single cell it is a really big number of nanomachines working, and they actually create another nanomachines. So nature has already created those assemblers we are looking for. Using that machines to create our own machines is bionanotechnology.Nanotechnology is a pretty new science. It began with the alchemists, then continued with the chemistry and in the 20th century it has been improved by nuclear physics.In the other hand biology began to play with molecules so the biotechnology started. If we join this two sciences we have a good way to manipulate individual atoms to create everything we can imagine.Thanks to this we can create specific nanomachines to work in many different fields, but the most important is medicine.
