Imagine a simple blood test that could detect cancer so early that it’s quite curable. What a reassurance to a cancer surgery patient whose test confirms no residual cancer throughout his body!
Researchers developed a drug that may stop the spread of cancer cells, but needed to develop a process for introducing the drug without damaging healthy tissues. The scientists turned to nanoparticles, objects so small that 800 of them could fit in the width of a human hair. These tiny particles can deliver the drug directly to cancer cells without damaging healthy cells.
