▎ 摘　　要

NOVELTY - Nanocomposite comprises graphene oxide-grafted polymer loaded with a medical active ingredient at 72 degrees C, where the medical active ingredient is released at a rate of more than 50% at low critical solution temperature (LCST) or at released at a rate of less than 25% at less than LCST. USE - The nanocomposite is useful for delivering an anti-cancer drug i.e. camptothecin (all claimed) to tumor cell of a target i.e. human body. ADVANTAGE - The water-soluble nanocomposite efficiently delivers the drug with excellent bio-solubility and stability to the site of the target in a controlled manner with reduced side effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing nanocomposite, comprising grafting polymer with graphene oxide.
