Story highlights Scientists in the U.S. are applying nanotechnology research to the battle against cancer and Ebola Man-made nanostructures would attach themselves to viruses or cancerous cells, nullifying them Nanostructured surfaces are already in use for medical conditions and implants, reducing the risk of infection <\/p>\n
From targeted remedies such as monoclonal antibodies to surgery, cancer has still managed to elude a treatment that discretely and separately attacks it alone. <\/p>\n
Nanotechnologies, however - the manipulation of matter at a molecular and even atomic scale to penetrate living cells -- are holding out the promise of opening a new front against deadly conditions from cancer to Ebola. <\/p>\n
According to Dr Thomas Webster, the chair of chemical engineering at Northeastern University in Boston, research into medical nanotechnology is gaining pace and the medical establishment is starting to sit up and pay attention. <\/p>\n
At the core of the technology is the ability to attach drugs, and in some cases metals and minerals, to nanoparticles that would then bind themselves to life threatening cancer cells or viruses. <\/p>\n
In one study, Dr Webster's team is developing methods to attach gold nanoparticles to cancer cells. <\/p>\n
Infrared light would then heat up the nanoparticles, killing the cancer cells with heat but leaving the healthy cells alive to do their job. <\/p>\n
\"This technology has been studied for the better part of a decade, but we're looking at ways of making it better,\" Dr Webster told CNN. \"One that we've created in the lab we've called 'nanostars.' <\/p>\n
\"A star shape has a lot more surface area, so they can kill cancer cells faster than a nanosphere because they heat up faster. <\/p>\n
\"Even if it's carrying a drug, a star has a lot more surface area on which to attach it -- it's got a different morphology.\" <\/p>\n
