INTRODUCTION:
AIDS:
Acquired Immunodeficiency Syndrome (AIDS), human viral disease that ravages the immune
system, undermining the body’s ability to defend itself from infection and disease. Caused by the human
immunodeficiency virus (HIV), AIDS leaves an infected person vulnerable to opportunistic infections.
Such infections are harmless in healthy people, but in those whose immune systems have been greatly
weakened, they can prove fatal. Our paper aims at the removal of the virus to from the RNA of the body
using the nanorobots.
HIV : Human Immunodeficiency Virus
The human immunodeficiency virus (HIV), which causes acquired immunodeficiency
syndrome (AIDS), principally attacks CD4 T-cells, a vital part of the human immune system. As a
result, the body’s ability to resist opportunistic viral, bacterial, fungal, protozoal, and other infection
is greatly weakened. Pneumocystis carinii pneumonia is the leading cause of death among people
with HIV infection, but the incidence of certain types of cancers such as B-cell lymphomas and
Kaposi’s sarcoma is also increased. Neurological complications and dramatic weight loss, or
“wasting,” are characteristic of endstage HIV disease (AIDS). HIV can be transmitted sexually;
through contact with contaminated blood, tissue, or needles; and from mother to child during birth or
breastfeeding. Full-blown symptoms of AIDS may not develop for more than 10 years after infection.
Anti-HIV using Nanotech
NANOTECHNOLOGY:
Nano is one billionth of one. Now we have the so-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 as well as 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.
