| 0:00:11 | researcher michael sailor hopes that finding a low particles in this file the light up |
|---|
| 0:00:16 | in the dark what they make treating cancer using your data on the cover |
|---|
| 0:00:21 | first i got a lighter they got a glow a second as a gotta find |
|---|
| 0:00:25 | that you |
|---|
| 0:00:26 | i didn't reply of c and everything and that it is can see three girls |
|---|
| 0:00:32 | what has been inari |
|---|
| 0:00:34 | and three of us have to answer |
|---|
| 0:00:37 | maggie and lydia both diagnosed and treated for breast cancer talk about the issues an |
|---|
| 0:00:43 | image mine words you have cancer |
|---|
| 0:00:47 | grammars effectively |
|---|
| 0:00:49 | but they would like nothing the matter what kind of the enhanced what the one |
|---|
| 0:00:55 | used to |
|---|
| 0:00:55 | that is languishing for me to make a decision did you feel create a few |
|---|
| 0:01:00 | tears |
|---|
| 0:01:01 | a you have eight invited you feel the prior as you have it is not |
|---|
| 0:01:07 | so |
|---|
| 0:01:08 | and not show everything and everything twenty four seven |
|---|
| 0:01:14 | at the university of california san diego sailors working to dramatically change those images a |
|---|
| 0:01:21 | cancerous treated |
|---|
| 0:01:22 | his request create at all particles that travel through the bloodstream latch on to cancers |
|---|
| 0:01:28 | in their early stages and destroyed |
|---|
| 0:01:31 | ideally you like to find the tumour when it's just one cell level a single |
|---|
| 0:01:35 | cell of the cancerous tumour that's just starting to form |
|---|
| 0:01:39 | we can do that now |
|---|
| 0:01:41 | but one of the really long term goals of nanotechnology is to be able to |
|---|
| 0:01:45 | do that |
|---|
| 0:01:46 | whatsoever has done for the past twenty years is figure a way to make their |
|---|
| 0:01:50 | low particles seek and destroy certain cancers in mice |
|---|
| 0:01:54 | the end of stuff has been key for my research program |
|---|
| 0:01:58 | because seventeen years ago received funding from the national science foundation c or wasn't thinking |
|---|
| 0:02:04 | he has trying to figure out how to make an apart |
|---|
| 0:02:09 | we didn't think about but in the body we just no well we can take |
|---|
| 0:02:12 | visible silicon chips break them up and making and of particles adam |
|---|
| 0:02:15 | what i silica |
|---|
| 0:02:17 | because silicon can degrade in the body so far most byproducts so we really like |
|---|
| 0:02:22 | to have an anal structure that once it gets into the body and does something |
|---|
| 0:02:25 | then it goes away |
|---|
| 0:02:27 | what's evolved is a recipe for making nontoxic narrow particles first take the silicon wafer |
|---|
| 0:02:33 | same used to make computer chips and generate induced by using an electrochemical back |
|---|
| 0:02:40 | punches tiny holes in the way for each ten thousand times smaller than the diameter |
|---|
| 0:02:45 | of human here |
|---|
| 0:02:47 | those holes are small but they're not so small that you can't loaded drug |
|---|
| 0:02:51 | into those force what they are very small silicon sponges but the not that small |
|---|
| 0:02:58 | there are still pretty big |
|---|
| 0:02:59 | the next step is to turn the spongy waivers in the narrow particles |
|---|
| 0:03:03 | so we have here is an ultrasonic bath |
|---|
| 0:03:07 | basically a jury cleaner |
|---|
| 0:03:09 | ultrasonic sound waves break up the silicon sponges and the smaller and smaller pieces |
|---|
| 0:03:14 | these are quite you know structures these are still that microns scale we keep doing |
|---|
| 0:03:19 | this process for valley hours these things would be small enough that we can inject |
|---|
| 0:03:22 | them inside the body |
|---|
| 0:03:23 | particles are also chemically coded to that of fluorescent well |
|---|
| 0:03:29 | i want them to get into the body swim around inside the body find the |
|---|
| 0:03:32 | tumour and then global and then allow us to be able to image |
|---|
| 0:03:36 | today that all particles injected in mice are successfully helping researchers find certain cancers sailor |
|---|
| 0:03:43 | hopes five to ten years as materials not be proved safe and effective for |
|---|
| 0:03:50 | so that's one of the goals of nanotechnology you can build these vessels that can |
|---|
| 0:03:54 | hold |
|---|
| 0:03:55 | a drug that would normally be very toxic the body |
|---|
| 0:03:59 | and in fact it's very toxic the tumour to |
|---|
| 0:04:02 | and it holds that drive pizza from getting out until it finds the tumour and |
|---|
| 0:04:06 | then it opens up and let's about |
|---|
| 0:04:08 | what keeps it we're going but are zeros are dying every day and i get |
|---|
| 0:04:14 | letters i'm dying cancer my wife assigning cancer my son design can see my nephew |
|---|
| 0:04:19 | was dying of cancer can help us because but also i saw fixed point theorem |
|---|
| 0:04:25 | steam |
|---|
| 0:04:26 | future site is importance stress or having the personal interaction with the with a an |
|---|
| 0:04:33 | old friend who who's you know husband died of cancer now on actually your mother |
|---|
| 0:04:38 | in law has got cancer and now she's afraid that are daughters gonna have the |
|---|
| 0:04:42 | same cancer "'cause" you know some generic can indication there |
|---|
| 0:04:47 | you know |
|---|
| 0:04:50 | you do you can do you can see survivor i really detection is fine |
|---|
| 0:04:57 | unless anything have to remove that the sooner that they you know the timetables the |
|---|
| 0:05:03 | better quality of life would you take the target |
|---|
| 0:05:07 | since that answers the mis |
|---|
| 0:05:12 | size nation and prosper |
