Detecting cancerous tumors before they’re visible to the human eye


yeah he talked about storing the library of
congress in a device the size of a sugar cube making materials that are stronger
than steel and a fraction of the weight and being able to detect cancerous tumors
before they’re visible to the human eye what’s what’s really exciting today is
that we have both the nanomaterials part you know such as particles and devices
that are enabling us to really resolve cancer at the level of small numbers of
cells sometimes it’s been said single cells
but we are working to do this much better than ever before we have the
materials do this the materials we’re using are much much brighter much
brighter and enable us to really get down and see a few cells and then
coupled with the device which has the ability now to resolve these small
numbers of cells in a way that was not realized in the past uniting
these technologies together to do a much better job of picking up small
metastases in tissues is truly an exciting area and we are all working
towards that goal so the patient outcomes will be further improved in the
future diagnosing and detecting cancer at this very early stage is really the
single best path towards surviving the disease solid tumors which are
developing in the body are shedding cells into a blood circulation
levels of the circulating tumor cells can be prognostic of the stage of the
disease nanotechnology-based devices which are now being developed allow for
capture and interrogation of circulating tumor cells from blood sample in ex vivo
environment with incredibly high accuracy the trouble is that one milliliter of
blood may contain less than hundred of tumor cells while it carries several
millions of white blood cells and even billions of red blood cells so imagine
how sensitive and specific the capture technique needs to be in order to fish
out tumor cells from this complex mixture yet newly designed nano devices are
actually capable of identifying few or even one tumor cell in the blood sample
of the patient
