will be used for the purpose of maintaining and protecting the human body
against pathogen

There is no technology for the treatment of AIDS. Some of
the drugs of specific composition are given to the patients depending on the
intensity of the disease. The drugs using nowadays are able to increase the
lifetime to a few years only. To make the treatment more specific, we use the
nanodevices that use nanosensors to sense the AIDS infected WBC’s. In this we
are using nanorobots to get back the HIV infected WBC’s. By doing so constant
levels of WBC’s are maintained in the blood stream.
In India more than 50 lakhs of people are
infected by this dreaded disease and it constitutes 10% of the total infected.
We are doing research on this paper and we hope that this theoretical approach
can be made practical in the near future, so that the killer disease AIDS could
also be made in control on the hands of Human with the emerging new technology
like NANOTECHONOLOGY which has a Bi o-medical Application.
Nano is one billionth of one. Now we have
the so NANOTECHNOLOGY called microprocessors and microarray technology that
would reach the nano level within a few decades, we suppose. Some call this
technology to be nanotechnology and some others name it the molecular nanotechnology,
to be specific.
REASONS FOR APPLYING
NANOTECH TO BIOLOGICAL SYSTEMS
Most animal cells are 10,000 to 20,000
nanometers in diameter. This means that nanoscale devices (having at least one
dimension less than 100 nanometers) can enter cells and the organelles inside
them to interact with DNA and proteins. Tools developed through nanotechnology
may be able to detect disease in a very small amount of cells or tissue. They
may also be able to enter and monitor cells within a living body.
Miniaturization will allow the tools for many different tests to be situated
together on the same small device. This means that nanotechnology could make it
possible to run many diagnostic tests simultaneously with more sensitivity. In
general, nanotechnology may offer a faster and more efficient means for us to
do much of what we do now
NANOMEDICINE
The emerging field of nanorobotics is aimed
at overcoming the shortcomings present in the traditional way of treatment of
patients. Our bodies are filled with intricate, active molecular
structures. When those structures are damaged, health suffers. Modern medicine
can affect the work of the body in many ways, but from a molecular viewpoint it
remains crude. Molecular manufacturing can construct a range of medical
instruments and devices with greater abilities. The human body can be seen as a
workyard, construction site and battleground form molecular machines. It works
remarkably well; using systems so complex that medical science still doesn’t
understand many of them.
BIOMEDICAL APPILICATIONS OF
NANOROBOTS
The enormous potential in the biomedical
capabilities of nanorobots and the imprecision and side effects of medical
treatments today make nanorobots very desirable. But today, in this
revolutionary era we propose for nanomedical robots, since they will have no
difficulty in identifying the target site cells even at the very early stages
which cannot be done in the traditional treatment and will ultimately be able
to track them down and destroy them wherever they may be growing. By having
these Robots, we can refine the treatment of diseases by using biomedical,
nanotechnological engineering.
WHAT IS A MEDICINAL
NANOROBOT
?
According
to current theories, nanorobots will possess at least rudimentary two-way
communication; will respond to acoustic signals; and will be able to receive
power or even re-programming instructions from an external source via sound
waves. A network of special stationary nanorobots might be strategically
positioned throughout the body, logging each active nanorobot as it passes,
then reporting those results, allowing an interface to keep track of all of the
devices in the body.
A doctor could not only monitor a patient’s progress but change the instructions of the nanorobots in vivo to progress to another stage of healing. When the task is completed, the nanorobots would be flushed from the body.

Nanorobot
performing operations on blood cells
Nanorobotic phagocytes called microbivores
could patrol the bloodstream, seeking out and digesting unwanted pathogens
including bacteria, viruses or fungi. Each nanorobot could
completely destroy one pathogen in just 30 seconds - about 100 times faster
than natural leukocytes or macrophages - releasing a harmless effluent of amino
acids, mononucleotides, fatty acids and sugars. No matter that a bacterium has
acquired multiple drug resistance to antibiotics or to any other traditional
treatment. The microbivore will eat it anyway, achieving complete clearance of
even the most severe septicemic infections in minutes to hours, as compared to
weeks or even months for antibiotic-assisted natural phagocytic defenses,
without increasing the risk of sepsis or septic shock. Related nanorobots could
be programmed to recognize and digest the cancer cells and to clear circulatory
obstructions within a minute in order to rescue stroke patients from ischemic
damage.
More sophisticated medical nanorobots will be
able to intervene at the cellular level, performing surgery within cells.
Physician-controlled nanorobots could extract existing chromosomes from a
diseased cell and insert newly manufactured ones in their place, a process
called chromosome replacement therapy. This would allow a permanent cure of any
pre-existing genetic disease, and permit cancerous cells to be reprogrammed to
a healthy state.
