• Summary

HOW MANY PEOPLE DIE FROM CANCER IN THE WORLD EACH YEAR ?

• Approximately 7.6 million people die from cancer each year (according to an article titled "ACS Report Focuses on Global Cancer Toll" which was published by the American Cancer Society-2012)

• Viet Nam: -240.000 – 250.000 people are being cancer-150.000 new each year-75.000 dead (2010 )

Nanoparticles

-Most animal cells are 10,000 to 20,000 nanometers in diameter. nanoscale devices (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.

Nanoshell absorbs heat

− Nanoshells have metallic outer layer and silica core− Selectively attracted to cancer shells either through a

phenomena called enhanced permeation retention or due to some molecules coated on the shells

− The nanoshells are heated with an external energy source killing the cancer cells

- quantum dots to antibodies that guided them to prostate tumor sites in living mice, where they clumped together and were visible using a simple mercury lamp.

APPLICATIONS AND PROMISES

• Cantilevers Can Make Cancer Tests Faster and More Efficient

• Kill the cancer cells without affect to other cells

• Can deliver more of the active ingredient and control more precisely how quickly it is released compared with current leading cancer drugs.

• Cancer treatment by grammar rays(US) : 15.000 – 25.000 USD ((300.000.000 – 500.000.000 vnd)

• Many new drug treatments cost nearly $100,000 a year

• $93,000 for vacxin which can adds four months' survival, on average, for men with incurable prostate tumors.

POTENTIALS

• More cheaper than the traditional methods ( drug ,vacxin , UV ….)

• Low effect to the body (compare with Chemotherapy, Radiation Therapy…)

• Cancer treatment (until now) : tumor's natural recruitment of monocytes, Liver Cancer Treatment, Lung Cancer Treatment, Vaginal Cancer Treatment , Leukemia Treatment Overview….

• Bright futures in uses

CHALENGES

• Nanostructures can be so small that the body may clear them too rapidly for them to be effective in detection or imaging.

• Larger nanoparticles may accumulate in vital organs, creating a toxicity problem.

• Difficult to approximate amount of nanopartiles

• Cytotoxic Effect
