The researchers at North Western University have developed a new device that has the advantages of nanodiamond and the new device could be useful for delivering cancer drugs directly to the desired spots. The device uses a microfilm device for treating cancer cells in the localized regions, where certain cancer cells remain after surgical removal of the tumor.

Dr Ho led the research that has experimentally demonstrated the use of the device for releasing chemotherapeutic drug doxorubician for over a period in consistent manner. The device is as a part of surgery can be implanted in the localized region, from where the tumor is being removed.

Researcher embedded drug carrying nanodiamonds in the FDA approved polymer parylene, as the surface area of the nanodiamonds is much larger and therefore large amount of the drug can be loaded through the device. After loading the chemotherapeutic agent doxorubician, the researchers found that the drug was slowly and consistently released for one month.

In absence of nanodiamonds, researchers found that all the drug was released on the same day and therefore the presence of the nanodiamonds made the device useful and effective in controlled cancer treatment. The other advantages of nanodiamonds is that these are useful for delivering any types of chemotherapeutic drugs and at the same time, these can easily be suspended in water also, which is one of the essential properties required for a good drug delivery device.
