-
1:11 - 1:12Jack Andraka: So there I am.
-
1:12 - 1:15No, that was the entire talk, bye.
-
1:16 - 1:19We have been talking a lot
about this thing called cancer. -
1:19 - 1:22It's really near and dear to all of us.
-
1:22 - 1:26But, imagine a world without cancer.
-
1:26 - 1:32What if there was a sensor
that was like a diabetes test strip -
1:32 - 1:37that could detect cancer
for less than 3 cents in 5 minutes. -
1:37 - 1:43Imagine a 168 times faster,
over 26,000 times less expensive, -
1:43 - 1:46and over 400 times more sensitive.
-
1:46 - 1:49Well, I created such a strip.
-
1:50 - 1:52Basically, I was motivated to do this
-
1:52 - 1:57because I had a close family member
that passed due to pancreatic cancer. -
1:58 - 2:01It's a really devastating disease.
It's the death sentence basically. -
2:01 - 2:03You can see that, after 5 years,
-
2:03 - 2:08only 5.5 percent of people
who are initially diagnosed, will survive. -
2:08 - 2:10That is a staggering statistics.
-
2:10 - 2:14Why as a society
that is so technologically advanced -- -
2:14 - 2:17should this statistic be acceptable to us.
-
2:17 - 2:21So, then, I got really interested
and I started doing a bit of research. -
2:22 - 2:24What I found is that there are
these certain proteins. -
2:24 - 2:27They are found in your blood
at higher concentrations -
2:27 - 2:29when you have pancreatic cancer.
-
2:29 - 2:32I was looking at one, called mesothelin.
-
2:32 - 2:38It's highly overexpressed by pancreatic cancer
as well as [at] the early stages. -
2:38 - 2:43Where, if you can find it in those stages,
then it has close to a 100% survival rate -
2:43 - 2:45rather than 5.5%.
-
2:46 - 2:49But, also a main problem
with our current diagnostic test -
2:49 - 2:53for pancreatic cancer --
it's grossly inaccurate. -
2:53 - 2:56It diagnoses like, for example,
inflamation of your pancreas. -
2:57 - 2:59That to me is unacceptable.
-
2:59 - 3:03A 70% sensitivity
and less than that for specificity -- -
3:03 - 3:06[Which] means it gives
tons of false positives and false negatives. -
3:07 - 3:10So then, through these really cool things
called carbon nanotubes -- -
3:12 - 3:15They are the superheros
of material science. -
3:15 - 3:19There are these atom-thick tube of carbon
and they have these fantastic properties. -
3:19 - 3:21So, I am super interested in that.
-
3:21 - 3:26I began formulating an idea
in unlikely place, biology class. -
3:26 - 3:30We were learning about antibodies
which are basically lock and key molecules -
3:30 - 3:33that bind specifically
to a certain protein. -
3:33 - 3:36In this case,
the cancer biomarker, mesothelin. -
3:36 - 3:38Then, I had an idea.
I was reading this paper -
3:38 - 3:42in biology class
-- about carbon nanotubes -- -
3:42 - 3:45I knew about this protein, mesothelin,
and we were learning about antibodies. -
3:45 - 3:48It is kind of like a connect-the-dots puzzle
where you form a draft -
3:48 - 3:50where in this case it is like a sensor.
-
3:51 - 3:53So, here is the idea I came up with.
-
3:53 - 3:57You have a network of the single walled
carbon nanotubes and antibodies. -
3:57 - 4:00What happens is --
when you put a blood sample -
4:00 - 4:03that contains that target protein in it
on this network, -
4:03 - 4:08that protein will go into the network
and form a larger molecule with that antibody. -
4:08 - 4:11This causes an electrical change
in the sensor. -
4:12 - 4:16I can actually measure this
with a 50 dollar ohmmeter from Home Depot. -
4:16 - 4:20And it is really easy to produce.
-
4:20 - 4:22All you do is to create
uniform dispersion out of these. -
4:22 - 4:26You mix it up with
these carbon nanotubes and this antibody. -
4:27 - 4:29You just dip stick that is
like a piece of filter paper. -
4:29 - 4:31It's really, really simple.
-
4:31 - 4:33Then, you dry it
and you use it for a certain time. -
4:33 - 4:35That's not that hard.
-
4:35 - 4:38You just measure it
with this 50 dollar ohmmeter. -
4:38 - 4:41It requires less than a sixth
of the drop of blood. -
4:41 - 4:44It is a tiny prick to your finger.
-
4:44 - 4:48What you have to do for detecting a disease
such as pancreatic cancer [is] -- -
4:48 - 4:51when a protein is overexpressed
you have to set a cutoff level. -
4:51 - 4:55If it's above this, then,
it's at an abnormally high level. -
4:55 - 4:58If't is below that, then,
it's kind of normal and you are OK. -
4:58 - 5:01So, I choose mine
as 10 nano grams per mL. -
5:01 - 5:03A nano gram is a tiny amount.
-
5:03 - 5:06Think it of as one billionth.
-
5:06 - 5:09So, pretty small.
-
5:11 - 5:15Then, essentially what I did is, I had to test
whether my sensor was actualy working. -
5:16 - 5:19I took about 100 patients
-
5:19 - 5:23who had pancreatic cancer
ranging in its stage. -
5:23 - 5:26You can see they are all above this 20 ng.
-
5:26 - 5:28That's well above the 10 ng per mL cutoff.
-
5:28 - 5:30So, I had a 100 percent sensitivity.
-
5:31 - 5:34Them, I had negative cancer samples,
healthy patients. -
5:34 - 5:37People who did not have pancreatic cancer,
maybe some other condition. -
5:37 - 5:40Those are all below 10 ng for mL.
-
5:40 - 5:44That means that is not giving any false positives
or any false negatives. -
5:44 - 5:47That means a 100% accuracy
as [its] diagnosis. -
5:47 - 5:50This has the potential
to save thusands of lives, -
5:50 - 5:53reshaping how we think of
cancer diagnostics. -
5:54 - 5:58In addition to this, what happens is this --
also I found we could look at -
5:58 - 6:01how effective a chemotherapeutic treatment
or a regimen -
6:01 - 6:03as well as how effective your surgery is.
-
6:03 - 6:05You can see it here that
-
6:05 - 6:09for each of different chemotherapeutic drugs
-- I tested five on mouse models -- -
6:09 - 6:12they all have different levels of mesothelin.
-
6:12 - 6:15So, you could effectively see how effective
your cancer drug treatment is. -
6:15 - 6:17You could look at
drug resistance, for example. -
6:18 - 6:24With this, I have created a sensor
that can detect pancreatic cancer. -
6:24 - 6:28It is very simple. It is very rapid
-- taking 5 minutes for 3 cents. -
6:28 - 6:31It's non invasible.
It's sensitive and selective. -
6:31 - 6:35But in addition, compared to the current gold standard
of pancreatic cancer detection, -
6:35 - 6:37it is a 168 times faster,
-
6:37 - 6:42over 26,000 times less expensive
and over 400 times more sensitive. -
6:42 - 6:45That is not actually, including --
that you need specific practice -
6:45 - 6:48like a university training
in order to conduct that gold standard, -
6:48 - 6:54as well as it requires this expensive bulky machine
to read this thing called ELISA. -
6:54 - 6:57Whilst mine, it's a 50 dollar ohmmeter
from Home Depot. -
6:57 - 7:00Also, the protein I am detecting,
called mesothelin, -
7:00 - 7:03it is overexpressed
in both ovarian and lung cancer. -
7:03 - 7:06Through this sensor, [that] is a generic sensor
for those two cancers, -
7:06 - 7:12but also implications are that certain protein
is found in 40 different types of cancer. -
7:12 - 7:15This sensor, is detecting
nearly every form of cancer. -
7:16 - 7:18This has limitless applications.
-
7:18 - 7:22What happens is you just change
this antibody in the sensor, -
7:22 - 7:24you can detect anything, any protein.
-
7:24 - 7:26That means other forms of cancer,
other diseases -
7:26 - 7:30such as E Coli, Rotavirus, Salmonella,
and those HIV, AIDS. -
7:30 - 7:34All those cancers and diseases
are plague us. -
7:34 - 7:38Thusands, millions, billions of lives
can be saved with this technology. -
7:38 - 7:41Also, it can look at
how effective our treatment is. -
7:41 - 7:44So, this will reshape
how we think of medicine. -
7:44 - 7:47We will now have
a simple diabetic test strip -
7:47 - 7:50that can detect your disease
in 5 minutes for 3 cents, -
7:50 - 7:56but also tell you how to optimally
cure the disease and treat it. -
7:56 - 8:01And, so --
Oh, two slides are missing. -
8:02 - 8:05My final conclusion,
what I am leaving you with, -
8:05 - 8:08is that I am not the only one
who can do this. -
8:08 - 8:10Anyone can.
-
8:10 - 8:12It just took me 200 emails
and a bunch of hardwork to do it, -
8:12 - 8:15but that is a different story.
-
8:15 - 8:17But, you just have to ask yourself.
-
8:17 - 8:20Imagine a world -- or what if --
-
8:20 - 8:24you can become like me and hopefully
have a very happy running up to a stage. -
8:24 - 8:26Thank you.
-
8:26 - 8:28(Applause)
