Carbon Nanotubes: Now in fluorescent form

by on Jun.22, 2011, under Articles, Science

Fluorescent Nanotubes Enhance Mouse Imaging [Kurzweil AI]

So in the past we’ve learned that Carbon Nanotubes can be used to deliver drugs into the body quickly, or possibly even a targeted fashion. Now we can paint them fluorescent and inject them into the body and be able to track and image their progress with greater depth an accuracy than standard biocompatible dyes.

This means we can both deliver drugs and watch them get delivered in real-time. An amazing step in medicine.

Okay peoples. That is my backlog of Carbon Nanotube news. So things will be slower now as the sudden explosion of discoveries seems to have tampered off to about once a week, rather than once a day. But as you can see, Carbon Nanotubes will be a savior and our destruction! All shall love and despair!
