Researchers around the world have been investigating the benefits of using nanoparticles in the treatment and destruction of cancerous tumor cells. These treatments have included delivering targeted medicine with nanorobots as well as trying to destroy individual tumor cells with the use of nanoparticles. Researchers at the University of Cincinnati have experimented with the use of electromagnetically-heated iron-oxide nanoparticles to destroy individual tumor cells and found that an increase of tumor-cell temperature of only ten degrees was enough to destroy the cells. This is especially beneficial in leaving healthy cells undamaged as they are more resilient to the rise in temperature.
After conducting experiments, the University of Cincinnati research group found that a polyacrylic acid (PAA) coating over the iron-oxide particles was most efficient at heating up to the proper temperature in order to destroy the tumor cells most efficiently while leaving healthy cells unscathed.
