An aspect of nanotechnology that can be improved?
Question by Farrah A: An aspect of nanotechnology that can be improved?
I have to write a research paper on an aspect of the field i am going into that could be changed or somehow..improved. For example..if i was going into nursing i would write about the different needles used. What are some aspects of nanotechnology that can be improved? i just need somewhere to start, because my mind is so broad on this subject.

Under the heading of containment.
It is well known that small pollutant particles present serious health dangers. They come from natural sources e.g. fire and volcanoes, and from man made sources e.g. cars, trucks, planes. Photocopy toner is dangerous to inhale.
Any manufactured nonoparticles need to be controlled for use in the environment for which they were intended. a) If they reproduce – in the future – then that must be tightly controlled!
New, fragile designs may be needed for medical remediation. Subtleties fo scale have surfaced showing that the way natural cells work have a lot to teach us. Viscosity is a major factor at nanoscales.
Nanoparticles may need to communicate with each other and with a central control supervisor…

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.

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.

Viruses are nanotechnology (how a virus works)
Download high quality version here: www.megaupload.com There are many methods of corrupting human DNA, starting with EMF, vaccinations and ending with GM foods. Viruses are artificial nanotechnology (which does not necessarily mean MAN-MADE) created especially for this purpose. According to recent studies 32% of human genome consists of the information encoded by virus-like elements and transposons. Viruses are non-living microscopic particles that attack healthy cells within living things. They do not have the characteristics of living things and incapable to metabolize. Viruses are not alive, so they do not have a need for food like living organisms. Viruses do not have an organized cell structure. They are so light that they can float in the air or water, be passed on to other organisms if touched, and fit anywhere. Viruses invade the cells of both plants and animals. They reproduce inside healthy cells causing diseases that are hard to treat. Viruses can not reproduce by themselves like bacteria or cells. They must attach themselves to the cell membrane of animals, or cell wall of plants and inject a part of their DNA into the cells of the host organism.. They do this by using a hollow tube structure to puncture the cell wall/membrane and pass its DNA into the cell. New virus cells are incubated inside the invaded cell. Once the virus DNA reproduces itself inside the cell, it uses the natural process of osmosis to leave the cell. These new virus cells attach to other …
