Development

**Development **
as.....d Nanotechnology is the engineering of atomically precise structures, and ultimately, molecular machines. The prefix //nano// refers to the scale

of these constructions. A nanometer is one-billionth of a meter, the width of about five carbon atoms nestled side by side. The machine comprising

many thousands of molecule-sized mechanical parts (resembling macroscale gears, bearings, and rachets). It will need motors to make things move,

manipulator arms or mechanical legs for dexterity and mobility. It will have a power supply for energy, sensors to guide its actions, and an onboard

computer to control its behavior. The nanorobot would travel through the bloodstream and would have to be smaller than the red blood cells (Freitas, 2010).

a.....sd Nanomedicine has been devoted toward improving health care. It has the potential to cure diseases and repair tissues by manipulating individual

cells. Current drug delivering systems had limited effects and long treatments were required. Now with nanomedicine, drug delivery device called

Nanocarriers. Nanocarriers are able to increase therapeutic activity while it decrease side effects. There are several types of nanocarriers being used

as a drug delivery devices, they are known as: polymeric micelles, liposomes, and dendrimers.

__ Drug Delivery __
Using engineered nanodevices and nanostructures, Nanomedicine is the repair, construction and

monitoring the control of human biological systems at the molecular level. Drugs with narrow therapeutic

indexes create a major challenge for pharmaceutical scientists. The application of Nanotechnology for the

delivery system of such drugs can hopefully eliminate this dilemia. Currently, in Nanotechnology, there are

different types of drug delivery systems that are most likely to have the highest impact. The United States Department of Education

has patented a drug delivery system.

__Disease detection__
In 2009, Toronto researchers developed an inexpensive microchip sensible enough to detect the severity

and the type of the diseases. A new method of cell manipulation doesn't require the attachment of labels to the

cells and no need for labor preparation. With this method it's able to sort and move cells, which allow greater efficiency

in disease detection. In today's methodology in processing blood work, it may take hours or even days to complete.

The reason is that the concentration of the diseased cells in a blood sample could be so low that it will take a long time for them to bump into the

sensor. For example, in the early stage of cancer there could be one tumor cell for every billion healthy cells; making it difficult to detect.

__Disease Treatment__
In just a few decades, nanomedicine will probably be the main method to tackle any disease, from a sore throat

to cancer. This treatment is non-toxic and biodegradable, which can increase the effectiveness of fighting cancer.

Compared to chemotherapy the new method is more effective, increases maximum dose, decreases toxicity, and

enhances the ability to target cancer cells.

Nanotechnology is the study of controlling devices on a molecular

level. Nanotechnology is the basis of nanomedicine, and

nanomedicine has been developing at a very fast pace

since a lot of countries are interested and anxious to see how far

can this technology really reach. In the year 2000, there was a

huge improvement with nanotechnology concerning the biological

part with the development of low friction carbon nanotubes and

the nano tweezers. The Carbon nanotubes are one of most

promising materials for nanomedicine, since it can help for drug

deliveries.
