Could Electronically Controlled Drugs Reduce Adverse Effects? (CNET)
Could electronically controlled drugs reduce side effects? | Cutting Edge - CNET News:
In the realm of oncology this could have especially dramatic ramifications.
Excerpt:
"Reporting in the journal ACS Nano, researchers led by Dr. Xinyan Tracy Cui at the University of Pittsburgh say their new approach allows them to electronically control the release of very specific amounts of drugs to certain parts of the body. To do this, they incorporated extremely thin nanosheets of graphene oxide that were loaded with the anti-inflammatory drug dexamethasone into a polymer scaffold that conducts electricity. By zapping the nanosheets with an electric current, they were able to release the drug -- using the thickness of the sheets to control how much drug was being carried, and the number and magnitude of zaps to control how much of the drug was released."
