Researchers from two
institutions, Brown University and the University of Akron are leading the way
in developing breast implants that deter or even detect
cancer cells. These advancements might have a huge impact on women who
have had breast cancer or those with a history of the disease in their family.
Biomedical scientists at
Brown University have published results in the journal, Nanotechnology,
documenting their creation of an implant with a microscopic
"bed-of-nails" surface that prevents cancer cells from dwelling and
thriving.
"It's a surface
that's hospitable to healthy breast cells and less so for cancerous breast
cells," said lead researcher, Thomas Webster. "This is like a
bed-of-nails surface to them."
Webster and Lijuan Zhang,
a chemistry graduate student, tested various types of raised surface implants
and discovered that those with microscopic "pimples" measuring
23-nanometers each were most successful in helping healthy cells to grow. As a
point of reference, a nanometer is 1/50,000th the width of a human hair. After
just one day, this surface yielded 15 percent more healthy endothelial breast
cells compared to a normal surface in tests. Researchers hope human trials
using this technology will begin within five years.
