Healing Stones – Part 3: More Targeted Cancer Therapy

All that glitters is not gold.  Sometimes it is cancer. How about gold-plated cancer? We can do that now, or more technically: gold nanoparticles infused with an antibody called cetuximab attach to growth factors (EGFR) expressed on the surface of some cancer cells.  In other words, bind just the right antibodies to gold nanoparticles, inject them into tissue, and cancer cells will be covered with gold. Ok, … Continue reading Healing Stones – Part 3: More Targeted Cancer Therapy

Healing Stones – Part 2: Targeted Cancer Therapy

How do you get a nano-robot to target and kill just cancer cells but leave healthy cells alone? Think like a suicide bomber: Carry a concealed mass killing weapon like a bomb, Act and look like you belong, Get into the enemy’s site, and Blow it up. Nanotechnology for medicine does not necessarily mean robotic machinery. On the nanometer scale, the mechanism is more like … Continue reading Healing Stones – Part 2: Targeted Cancer Therapy
