researcher michael sailor hopes that finding a low particles in this file the light up
in the dark what they make treating cancer using your data on the cover
first i got a lighter they got a glow a second as a gotta find
that you
i didn't reply of c and everything and that it is can see three girls
what has been inari
and three of us have to answer
maggie and lydia both diagnosed and treated for breast cancer talk about the issues an
image mine words you have cancer
grammars effectively
but they would like nothing the matter what kind of the enhanced what the one
used to
that is languishing for me to make a decision did you feel create a few
tears
a you have eight invited you feel the prior as you have it is not
so
and not show everything and everything twenty four seven
at the university of california san diego sailors working to dramatically change those images a
cancerous treated
his request create at all particles that travel through the bloodstream latch on to cancers
in their early stages and destroyed
ideally you like to find the tumour when it's just one cell level a single
cell of the cancerous tumour that's just starting to form
we can do that now
but one of the really long term goals of nanotechnology is to be able to
do that
whatsoever has done for the past twenty years is figure a way to make their
low particles seek and destroy certain cancers in mice
the end of stuff has been key for my research program
because seventeen years ago received funding from the national science foundation c or wasn't thinking
he has trying to figure out how to make an apart
we didn't think about but in the body we just no well we can take
visible silicon chips break them up and making and of particles adam
what i silica
because silicon can degrade in the body so far most byproducts so we really like
to have an anal structure that once it gets into the body and does something
then it goes away
what's evolved is a recipe for making nontoxic narrow particles first take the silicon wafer
same used to make computer chips and generate induced by using an electrochemical back
punches tiny holes in the way for each ten thousand times smaller than the diameter
of human here
those holes are small but they're not so small that you can't loaded drug
into those force what they are very small silicon sponges but the not that small
there are still pretty big
the next step is to turn the spongy waivers in the narrow particles
so we have here is an ultrasonic bath
basically a jury cleaner
ultrasonic sound waves break up the silicon sponges and the smaller and smaller pieces
these are quite you know structures these are still that microns scale we keep doing
this process for valley hours these things would be small enough that we can inject
them inside the body
particles are also chemically coded to that of fluorescent well
i want them to get into the body swim around inside the body find the
tumour and then global and then allow us to be able to image
today that all particles injected in mice are successfully helping researchers find certain cancers sailor
hopes five to ten years as materials not be proved safe and effective for
so that's one of the goals of nanotechnology you can build these vessels that can
hold
a drug that would normally be very toxic the body
and in fact it's very toxic the tumour to
and it holds that drive pizza from getting out until it finds the tumour and
then it opens up and let's about
what keeps it we're going but are zeros are dying every day and i get
letters i'm dying cancer my wife assigning cancer my son design can see my nephew
was dying of cancer can help us because but also i saw fixed point theorem
steam
future site is importance stress or having the personal interaction with the with a an
old friend who who's you know husband died of cancer now on actually your mother
in law has got cancer and now she's afraid that are daughters gonna have the
same cancer "'cause" you know some generic can indication there
you know
you do you can do you can see survivor i really detection is fine
unless anything have to remove that the sooner that they you know the timetables the
better quality of life would you take the target
since that answers the mis
