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.

Nanotechnology Introduces Nanorobots (reproduction)

Nanotechnology Introduces Nanorobots (reproduction)

Nanotechnology’s invention of nanorobots is theoretical microscopic devices that calculated on the scale of nanometers (1 nm equals one millionth of a millimeter). When fully realized from the hypothetical stage, they would work at the atomic, molecular and cellular level to perform tasks in both the medical and industrial fields that have heretofore been the stuff of science fiction.

In past generations some body identified with cancer may be offered a new option to chemotherapy (the traditional cure of radiation, which kills not just cancer cells but healthy human cells too, causing hair loss, exhaustion, sickness, depression, and a host of other symptoms as well). A doctor enthusiastic towards nanomedicine would give the patient an injection of a particular kind of nanorobot, which would seek out cancer cells and tear down them, dismissing the disease at the source, leaving healthy cells unharmed. The amount of the adversity to the patient will fundamentally be a stab to the arm. A person experiencing a nanorobotic treatment can hope to have no alertness of the molecular devices working inside them, other than fast betterment of their health.

Nanomedicine’s nanorobots are actually very tiny that they could with no trouble pass through the human body. Nanotechnology scientists report the external of a nanorobot would probable are constructed of carbon atoms in a diamondoid structure as of its motionless properties and other strength. Super-smooth surfaces would further lessen the possibility of activating the body’s resistant system, permitting the nanorobots to go about their business without hindrance. Glucose or natural body sugars and oxygen may be a foundation for force, and the nanorobot would have other biochemical or molecular parts depending on its task.

According to present theories, nanorobots would possess as a minimum basic two-way communication; would respond to acoustic signals; and would as well be able to get power or even re-programming instructions from an outside source via sound waves. A system of particular stationary nanorobots may be deliberately placed all through the body, logging every active nanorobot as it passes, and then reporting those results, permitting an line to keep pace of all of the devices in the body.

Working with materials that are a thousandth the diameter of a human hair, nanotechnology can be used in a number of industries. What are the most promising nano projects in Russia? Will the development of nanotechnology help turn Russia into a hi-tech giant? Well be talking about it with Aleksandr Losyukov, the Deputy General Director for International Co-operation at the Russian Corporation of Nanotechnologies
