Jack Andraka is not your ordinary
teenager. Instead of hanging out with friends or watching TV, Andraka prefers
working in a lab, looking for a new way to detect cancer.
The crazy thing
is, he actually did! At just 16 Andraka has created a new tool to detect
pancreatic cancer in its early stages that he says is cheaper, less intrusive
and better at detecting cancer than our current method. Anadraka’s test can fit
in your backpack. He told us that his breakthrough hinges on a material called
carbon nanotubes.
"They’re these long thin pipes of
carbon, they’re an atom thick and .150 the diameter of your hair. However
despite this they have these incredible properties, they are kind of like the
superhero material of science. For example: they are stronger than steel, they
can also transfer electricity better than copper. They have all these
applications. Then we have these things called antibodies; antibody is a type
of molecule that only reacts to one specific protein. In this case the protein
would be a cancer biomarker called mesothelin that circulates your bloodstream
at very high levels when you have these different types of cancers, like
pancreatic, ovarian and lung cancer. So you have this circulating mesothelin in
your bloodstream and I want to detect that.
Essentially what I do is weave
these antibodies into a network of carbon nanotubes so that you have a network
that reacts with one specific protein. Due to the properties of carbon
nanotubes, when the reaction happens, the network would change its electrical
properties based on the amount of protein present. I would measure that change
with a $50 meter I got from Home Depot and essentially I would be able to
detect cancer…and potentially any disease ranging from HIV/AIDS to Alzheimer’s."
Andraka
says " his test improves on the original pancreatic cancer test in a number of
ways.
Unlike our current pancreatic
cancer test which costs $800 per test and misses 30% of all cancers, my test
cost three cents, takes five minutes to run, doesn’t require specialized training
and it’s a lot smaller than the current test. Here are some statistics: it is
168 times faster, over 2600 times less expensive, and over 400 times more
extensive than our current standard of detection."
Andraka’s
innovation has turned him into something of a celebrity. He’s won a major
scientific award, given a TED Talk, and met some pretty interesting people.
Andraka says one of his highlights: ”It was really cool going to the State of
the Union and being able to talk to Obama. I only got to talk to him for like
five minutes, but it was insanely cool to talk to the world leader of democracy
about your science fair project.” During their conversation, President Obama
didn’t treat Andraka like a teenager but asked him about his experience trying
to get his test approved by the government regulatory agencies.
Andraka
expects that his test will be used in medical centers within the next two to
five years, after it receives approval from the Food and Drug Administration,
US.
