00:00:07;16 , 00:00:10;07 , What if we could screen for thousands of diseases

00:00:10;07 , 00:00:13;18 , all at once...with just a single drop of blood

00:00:16;09 , 00:00:19;02 , What if we could search out and destroy cancer cells

00:00:19;02 , 00:00:22;19 , without surgery or chemotherapy?

00:00:26;24 , 00:00:29;14 , What if we could restore eyesight by injecting

00:00:29;14 , 00:00:31;13 , tiny particles that help the body

00:00:31;13 , 00:00:33;06 , repair injured nerves?

00:00:37;14 , 00:00:39;16 , These scenarios may seem far-fetched

00:00:39;16 , 00:00:41;13 , but they are among the long term goals

00:00:41;13 , 00:00:45;11 , of researchers working in the new field of nanomedicine.

00:00:46;24 , 00:00:49;09 , But what is nanomedicine?

00:00:49;09 , 00:00:51;13 , Nanomedicine is the application of

00:00:51;13 , 00:00:53;23 , nanotechnology to medicine.

00:00:55;03 , 00:00:57;29 , Nanotechnology is the science of the small,

00:00:57;29 , 00:01:00;20 , the science, and now these days, also the

00:01:00;20 , 00:01:03;20 , engineering and applications of very small structures.

00:01:03;20 , 00:01:05;19 , It's kind of like a giant game of Lego

00:01:05;19 , 00:01:08;01 , only it is very small and the building blocks

00:01:08;01 , 00:01:09;28 , are molecules and atoms.

00:01:10;02 , 00:01:12;02 , If you look in biology

00:01:12;02 , 00:01:13;29 , most of the components of your cells

00:01:13;29 , 00:01:17;16 , and all of your proteins are all nanoscale objects.

00:01:19;09 , 00:01:21;19 , So what doctors need are tiny tools

00:01:21;19 , 00:01:23;14 , that can work with fantastic precision

00:01:23;14 , 00:01:24;28 , at the nanoscale

00:01:24;28 , 00:01:28;12 , the size of the smallest working parts of our bodies

00:01:30;07 , 00:01:32;15 , Nanotechnology has created so many

00:01:32;15 , 00:01:36;23 , materials with really unique and distinctive features.

00:01:36;23 , 00:01:39;17 , It gives us a new toolbox to try and address

00:01:39;17 , 00:01:41;19 , many unmet medical needs.

00:01:41;21 , 00:01:44;13 , How do you bring the drug to the right place?

00:01:44;13 , 00:01:46;19 , How do you avoid the biological barriers?

00:01:46;19 , 00:01:49;25 , These are problems that are very well-suited for a solution

00:01:49;25 , 00:01:52;01 , that is a teamwork solution.

00:01:53;04 , 00:01:55;10 , Hundreds of teams of researchers

00:01:55;10 , 00:01:58;18 , are exploring exciting new ways to better diagnose

00:01:58;18 , 00:02:01;16 , and treat disease through nanomedicine.

00:02:02;05 , 00:02:04;18 , Each new technique will need to go through

00:02:04;18 , 00:02:07;18 , years of testing to ensure that it will work

00:02:07;18 , 00:02:09;05 , and that it will be safe.

00:02:10;06 , 00:02:13;16 , I think that nanomedicine is going to bring us

00:02:13;16 , 00:02:16;03 , a number of really significant breakthroughs

00:02:16;03 , 00:02:17;17 , in the coming years.

00:02:17;17 , 00:02:19;14 , It's also going to allow us to evolve

00:02:19;14 , 00:02:21;05 , some of the current technologies

00:02:21;05 , 00:02:23;09 , into things that work a little bit better.

00:02:23;09 , 00:02:25;26 , If it is one of many ways, that's also very exciting

00:02:25;26 , 00:02:29;01 , because the bottom line is that we want people to be well.
