New innovations in nanomedicine may be coming your way soon!

It’s amazing the innovations happening in labs around the world right now.  Very soon we may have treatments for many more cancers that use nanoscale vehicles to deliver chemotherapy directly to tumors sparing healthy cells.  These drug vehicles are 200 times smaller than a red blood cell.  According to Scientific American’s April 2015 issue, labs at the University of Tokyo are researching several versions of nanodrug vehicles and are completing the final stages of clinical trials.  It is expected that research development speed will escalate in the next 5 years showing rapid growth in this exciting field.

The particles used to make up these drugs are cloaked in a variety of ways.  One way is they are made to “blend” in with the normal body tissues and therefore do not alert the immune system as a foreign body thus triggering their degradation.  They can also be constructed in a way to resist degradation by the bodies’ enzymes creating a longer life, thus allowing more of the chemotherapeutic agent to attack the cancer.  Some nanodrugs are created to be soft and flexibile allowing them to enter cancer tumors more readily and then degrade in the more acidic environment of the tumor where the chemotherapy drugs are released and are needed exclusively.  Other scientists are attaching cancer protein antibodies to these nanovehicles so that they are attracted to the cancer cells making delivery of their drugs very target specific.

This growing field of medicine could soon be the dominant way in which we fight cancer.  If you or someone you know is fighting cancer do your research and find out all the ways your cancer is being treated, your cancer may be the one where this therapy is being used!
