CANCER CELLS ONLY
ANCHOR LEAD: NEW TECHNOLOGY MAY HELP TARGET CANCER CELLS PRECISELY BUT LEAVE NORMAL NEIGHBORS ALONE, ELIZABETH TRACEY REPORTS
Can a technology known as a nanowire, developed by Andre Levchenko and colleagues at Johns Hopkins, finally deliver on the idea that somehow cancer cells can be preferentially killed but normal ones nearby left alone? Levchenko comments.
LEVCHENKO: There are some interesting potential applications in terms of delivery of the drug in the human body for example. We don’t think that it will be very easy to manipulate the wires just through the blood vessels, trying to guide them through the body to the organ of interest but we think we can have a vehicle that would be loaded with these wires and that would be a particle that we could bring the wires towards lets say a tumor and then locally we can release them and then within a tumor we can manipulate them and ultimately use them to deliver a drug and also affect a tumor in other ways. :30
The technology already works well in the lab and is providing much information on cellular communication, Levchenko says. At Johns Hopkins, I’m Elizabeth Tracey.
