Now from the Boston Museum of Science, Sci-tech today on NECN.

Now in Sci-tech today a device that could make cancer testing more available worldwide. It’s called the Nuclear Magnetic Resonance System and it’s actually been around for decades, so what’s new? A Harvard researcher has found a way to shrink it from 250 pounds to this device which weighs less than a quarter of a pound. Nano technology correspondent Alex Fiorentino joins us live from the Museum of Science in Boston.

 

Welcome Alex, how could this device help fight cancer?


-Well, Chad this is a device that detects cancer in the blood, so tumors release certain cancer markers into the blood and by detecting them we can do a much better job of diagnosing and monitoring cancer. So unfortunately the techniques we use to do this test can be pretty inconvenient so they often involve a laboratory equipment that’s very expensive and isn’t available to everyone. So for today what we are looking at is a different way of testing the blood for cancer called Nuclear Magnetic Resonance or NMR. And basically what NMR use is it’s like a MRI scan, excepting instead of scanning the whole body, you are only scanning a tiny sample of someone’s blood.


-All right, so this is based on a MRI scan but those aren't exactly cheap or convenient, how is this NMR different?


-Ur, well, in many cases actually not that much different so I have a picture here of an actual commercial MRI machine and you can see that it is pretty bulky device and it's also quite expensive, so this really doesn’t help make this testing more available to people. However, so, what we are talking about here is a scientist’s name, Nan , who’s an electronic engineer from Harvard University, and Nason saw the real problem with these big MRI devices was the giant magnet inside that. So there are two main components in every MRI machine, a magnet which poses on your blood sample with a magnetic field and a transceiver which zaps the sample and receives back the signals to detect what’s in the sample. So normally the magnet is by far the biggest and most expensive piece of an MRI machine and so a real MRI magnet would be many, many times bigger than this, and it would weight hundreds of pounds.

 But Nan and his adviser Donhe Kim realized that these big expensive magnets really won’t necessary, a tiny magnet would work just as well, you’ll just need the other component, the transceiver to be sensible enough. So Nan went to work on this, he is an electrical engineer so he completely redesigned the MR transceiver and within a few months he created this which is basically the same device, it’s got a magnet and a transceiver, but this is 1200 times smaller, 150 times more sensitive and 1400 times cheaper than a commercial MR machine.


-Well, that’s pretty amazing, so it just reworking the transceiver that allow it to shrink that device down to what you just showed us.


-Yeah, Pardon me, Chad.


-Yeah, go ahead.


-I was just gonna say that… So, shrinking that down was a huge part what made this possible, but also Doctor, Excuse me, Nan, borrowed a technique from some other researchers at Harvard, and that was to add magnetic nano particles to the blood samples so to explain why exactly who’d wanna do that. Let’s take a look at this model I have right here, so imagine that this red area is your blood sample and you’d add to it these magnetic nano particles, although in reality the magnetic nano particles are hundreds of thousands times smaller than this, but if there is no evidence of cancer in your blood sample then the nano particles just scattered around. But if you do have a cancer marker present in the blood then the nano particles are attracted to it, they stick to it and they form this cluster around it. This cluster is very, very easy to detect using an NMR . So what we done here is make this test much more sensitive, instead of trying find this one little cancer marker, you are able to find a big magnetic cluster that’s surrounding it.

Now from the Boston Museum of Science Scitech today on NECN. Well in Scitech today a device could make cancer testing more available worldwide. It’s called nuclear magnetic resonance system. And it’s actually has been around for decades. So what’s new? A Harvard researcher has found a way to shrink it in 215 pounds to this device which weight less than a quarter of a pound.

* technology correspondent N..T..joins us this live from the Museum of Science in Boston.

Welcome T..how could this device help bite cancer?

Well, *. This device will check the cancer in the blood, so tumors release certain tumor marks in the blood. By detecting them we can do a much better job in diagnosing and monitoring cancer. So unfortunately the techniques we used to do this test can be pretty inconvenient, so they often involve a laboratory equipment. It’s very expensive and isn’t available for everyone. So today what we’ve look at it’s a different way for detecting the blood cancer called nuclear magnetic resonance or NMR. And basically NMR is like a MRI scan.it’s not like setting up a scam in your whole body, you’re only scanning a sample of someone’s blood..

So this based on MRI scan, although exactly it’s cheaper and convenient. How was this and MRI different?

So in many cases actually they are not different. So I have a picture here of actually commercial MRI machine and you can see it’s a pretty *device. It’s also quite expensive. So this doesn’t help the testing quite more available. However, so so what we’re talking about here. er it’s a scientist name N.S..who’s a electrical engineer from Harvard University and N..S..saw this real problem with big and *was a giant magnet inside of it. So he made two components a MRI machine--a magent was pull on your sample with magnetic field and the transceiver with detecting the sample and receive bad signal to detect what’s in them. So normally the magnet is by far the biggest and the most expensive in MRI machine. So a really magnet would be many many bigger times than this and it weighs
hundreds of pounds. But N’s advisor *realized that this big expensive wasn’t necessary. A tiny one was just as well. You would need just another component, a transceiver to be sensible enough. So he went to work on it. He was an electrical engineer, so he completely redesign the MRI transceiver and within a few months he created this which is a basic same device --- a magnet and a transceiver. But this is 1200 times smaller, 115 times more sensitive and 400 times cheaper than commercial MRI machine.


Oh, that’s pretty amazing. So he’s just reworking the tranceiver that allow them to shrink that device to you just show to us?

Yes. Pardon. (主持人的名字)
Go ahead.

I just want to say that triming down was a huge part of made this possible.and doctor N.. borrowed techniques from some other researchers at Harvard and he added that magnetic particles to this blood samples. So I want to explain why he do that. Let’s take a look at this model I have it here. so imagine that it’s ready, it’s your bloody example. And you add this magnetic particles although in reality, magnetic particles are hundreds thousands smaller than this. But if there’s no evidence of cancer in your blood, then the magnetic particles are scattered around, but if you do have a cancer marker present in the blood, then the particles are tracking to them,stick to it and they form a cluster around. This cluster is very very easy to detect, using NMR. So what we’ve done here to make this test much more sensitive. It’s trying to find this one more a little cancer marker. You’re able to find a big magnetic cluster that sourrounding them.
All right, that’s a fascinating stuff. Thanks for joining us on this live today from the Museum of Science.

Thanks for having me a chance.

Now the technology correspondent Alex F joins us live from the Museum of Science Boston. Welcome Alex, how could this device help fight cancer?

We'll check. This is device that detects cancer in the blood. So tumors release certain cancer markers into the blood, and by detecting them we can do much better job of diagnosing and monitoring cancer. So unfortunately the techniques we used do this task can be pretty inconvenient. So they often involve a laboratory equipment that is very expensive and isn't available to everyone. So for today what we are looking at is a different way of testing blood for cancer called nuclear magnetic Resonance, or NMR. Basically what NMR is is if you have NMR scan except instead of scanning the whole body, you're only scanning a tiny sample of someone's blood.

All right, this is based on NMR scan, but those are exactly cheaper and convenient, how is this NMR different?

Well in making it's actually not that much different. So I have a picture here of actual commercial NMR machine and you can see that's pretty bulky device and it's also quite expensive. So this really doesn't help make this testing more available to people. However, so, what we are talking about here is a scientist named Nang Sun who is an electric engineer from Harvard University and Nang Sun saw the real problem with this big NMR device was the giant magnet inside them. So there are two main components that every NMR machine: a magnet which pulls your blood sample with magnetic field and transceiver which zaps the sample and receives back signals to detect what's in the  sample. So normally the magnet is by far the biggest and most expensive piece of NMR machine and so the real NMR magnet would be many many times bigger than this and would weigh hundreds of pounds. But Nang and his advisor, D realize that this big expensive magnet is really not necessary, a tiny magnet would work just as well. You would just need other component, transceiver to be sensitive enough. So not went to work on this is electric engineer, so he completely redesigns the NMR transceiver and within a few months, he created this, which is basically the same device magnet and transceiver, but this is 1200 times smaller and 150 times more sensitive and 1400 times cheaper than commercial NMR machine.

That's pretty much amazing. So he's just reworking the transceiver that a lot of shrink that device down, you just showed us.

Pardon me. (Yeah, go head.) I'm just gonna say that so tricking that down was a huge part of what made this possible. But also doctor Nang borrowed technique from some other researchers at Harvard and that was to add magnetic nano particles to blood samples, so to explain why exactly who want to do that, let's take a look at this model I have right here. So imagine that this red area is you blood sample and you add to it these magnetic nano particles although in reality the magnetic nano particles are hundreds of thousands of times smaller than this. But if there is no evidence of cancer in your blood sample then the nano particles just scatter around but you do have a cancer marker present in your blood, then the nano particles are attracted to and stick to it and form this cluster around. This cluster is very very easy to detect use NMR. So what we've done is to make this test much more sensitive. Instead of trying to find this one little cancer marker, you are able to find them big magnetic cluster that's surrounding it.

All right, Alex, that's fascinating staff. Alex F, thanks for joining us live today from the Museum of Science.

A Harvard researcher
has found the way to shrink it from 250 pounds to this device which weights less than a quarter of a pound. Nano technology correspondent Alex Fiorentino joins us live from the Museum of Science in Boston.

Welcome Alex, how could this device help fight cancer?

Well, Chad this is a device that detects cancer in the blood, so tumors released certain cancer markers into the blood and by detecting them we can do much better job of diagnosing and monitoring cancer. So unfortunately the techniques we use to do this test can be pretty inconvenient. So they often involve a laboratory the equipment thats very expensive and isnt available to everyone. So for today what we are looking for a different way of testing the blood for cancer called nuclear magnetic resonance or NMR. And basically what NMR use is its like a MRI scan, excepting instead of scanning the whole body, you are only scanning a tiny sample of someones blood.

All right, so this based on a MRI scan but those arent exactly cheap or convenient. How was this NMR different?

Well, in many cases actually not that much different, so I have picture here of an actually commercial NMR machine and you can see it's really portable/ bulky device, so it's also quiet expensive. so this really doesnt help make this testing more available to people. However, what we are talking about here is a scientists name Nan sun. Whos electronic engineering in Harvard university, and Nan son saw the really problem with these big MRI devices was the giant magnetic inside that.



So there are two main components in every MRI machine, a magnet which poses on your blood example with magnetic field and transceiver which zaps the example and we receives back the signals to detect whats in the sample. So normally the magnet was by far biggest and most expensive piece of an MRI machine and so the real MRI magnet would be many, many times bigger, would weight hundreds pounds.




But Nan and his adviser Donhe Kim realize that
these big expensive magnets really won
t necessary, a tiny magnet would work just as well. Youll need just another component, be transceiver to be sensitive enough. So Nan went to work on this, he is an electrical engineering, so he completely redesigned the MR transceiver, and with a few months, he created this which is basically the same device, its got a magnet and a transceiver. But this is 1200 times smaller and 150 times more sensitive and 1400 times cheaper than commercial MR machine.

Well, thats pretty amazing, so it just reworking the transceiver that allow it to shrink that device down to what you just show to us.

Yeah, Pardon me, Chad.



Yeah, go ahead.


I was just gotta say that. So shrinking that down was a huge part what made this possible? But also doctor,
Excuse me, Nan, borrowed a technique from some researchers in Harvard. and that was to add magnetic nano particles to blood samples. so to explain why
exactly who
d do that. Lets take a look this model I have right here, so imagine that this red area is your blood sample and youd add to it these magnetic nano particles, although in reality, magnetic nano particles are hundreds of thousands times smaller than this, but if there are no evidence of cancer in your blood sample then nano particles just scattered around.


But if you do have a cancer mark
er in blood then the nano particles are attracted to it. They stick to it and they form this cluster around it. This cluster is very, very easy to * detect using NMR. So what we done here is make testing much more sensitive, instead of trying to find this one litter cancer marker, you are able to find a bigger magnetic cluster that's surrounding it.

All right, Alex thats a fascinating stuff. Alex Fiorentino thanks for joining us.
